Kyosho Twin Force 4WD EP Monster Truck Kit

[StevePond]

http://www.rccaraction.com/pics/kyosho/kyoc0103.jpg

It appears Kyosho is ready to release an electric-powered version of the Mad Force monster truck. Little is known about the new truck, but the "Twin Force" implies that it will be powered by a pair of electric motors. This truck includes the same bold and distinctive Mad Force truck body with new decal graphics, and it appears new tires and wheels will be included, altough we're just going be appearances. The kit is listed as being available in late January.

Thanks to Brian for reminding us to post this information. ;)

[The_In_Kid]

wonder if it will crawl well?

[DCLXVI]

Probably not...the Mad Force uses 2-link suspension with some kind of torsion bar...from what I've heard from the Mad Force owners are that the suspension doesn't allow for that much articulation...

[Tamiya4ever]

Another truck to ad to my list of goodies for 2004. :D

[Tamiya4ever]

Were did that picture come from? :confused:

[atm92484_3]

That thing should have no trouble taking brushless power with the 1/8 scale drivetrain. Looks good.

[4wdmt]

kewl, thanks Steve for posting the Twin Force here. its only a matter of time now and more info will be available for this new MT.

if T-Maxx has an E-Maxx cousin, now the Mad Force has the Twin Force, very cool indeed. i hope HPI will release an E powered savage.

the good thing is - its a kit and the hop ups of the mad force / mad armor will fit this TF. added bonus points.

TH listed it for $299. i hope the price will still go down.

Tamiya4ever, check the "just announced" items of TH, youll see the same pics.

No, just changing the powertrain isn't going to help. It only gets barley a soda can of articulation, which is horrible for its size.

[BCat125]

I hope they didnt set it up as two motors on one spur gear because with two gear boxes it could have the same hop-up ability of the clodbuster.

[BriS]

I found it on Towerhobbies web site.

[BriS]

I hope they didnt set it up as two motors on one spur gear because with two gear boxes it could have the same hop-up ability of the clodbuster.

But if they did set it up with the 2 motors on 1 spur gear it might have the 3-speed set the Madforce has. :D

[metalry101]

Maybe it's just me, but don't the E-Maxx and the TXT-1 both have enormous hop-up potential? They both run a tranny w/ 2 motors feeding one spur. No you can't change the whole truck's configuration, but then what's the point of Kyosho or Tamiya releasing a truck anyways? So people can grab the axles and trannies?

Maxxcrazy~
The drivetrain can handle the power of BL, he didn't say anything about the suspension's flex.

Anyways, I'm hoping this truck kicks some ass. It'd be nice for my E-Maxx to have some competition. Also, I totally agree that HPI should make an electric Savage. I'd have to get both if they made them. I've already got an E-Maxx that's nicely modified.

[Tamiya4ever]

DOH!!! Ok. I know that it will take the nitro MF hopups with ease, I am wondering if the tranny is still chain driven and will it still have the 3 speeds.

[DCLXVI]

metalry, the TXT-1 is more than just usefull axles...the TXT-1 stock is as if not even more capable than most mod clods out there...

[Preston]

How many degrees of articulation does the TXT-1 have stock?

[Frapechino]

wel from those pics looks like motors on one spur... looks pretty good...

[BCat125]

Well i guess it really doesnt need to be a dual gear box truck, which it isnt judging fron thr pics). The chassis is already like an aftermarket one anyway. It doesnt seem like a good racing truck however because it looks very top heavy and looks like it is built to do wheelies. I guess ill have to wait until it comes out to judge it though.

[4wdmt]

thanks unobjectionable for the link. wow, 2 - 550 motors and 1 spur. i just hope they used 32p on their pinion so that i can interchange me E and TXT pinions, more gearing options. i also hope those battery holders can accomodate 7 cells.

can anyone comment with the steering set up of the mad force? its a carry over on this twin force also.

[Tamiya4ever]

It looks like the battery packs are mounted one on each side of the chassis.

YES YES YES, HPI so needs to make an electric Savage made to take advantage of the new brushless motors.

[4wdmt]

yup, it looks like the battery compartments are on both sides. but it seems its only designed to holds 6 cell stick packs. i hope there is still more options.

[metalry101]

DCLXVI~
Totally agree on the TXT-1. I meant the Clod and Jug. They were worthless piles except for the trannies and axles. But hell yes, the TXT-1 is an extremely capable truck right out of the box.

Unobjectionable~
Don't start the real monster truck BS. My E-Maxx is just as much of a "real" monster truck as a TXT-1.

[JohnnyShore]

As far as "Real" monster trucks go, I'm betting that within the next 10 years, you'll see full scale monster trucks running at least an independant front suspension.

At a Monster Jam show my club ran R/C's in last year at the Metrodome, a couple guys got a chance to talk with Dennis Anderson, and he said they've already been researching it. He looked over one of the T-Maxx's and commented "I wonder how far our big ones could fly if they had the suspension your little ones have?". A LOT farther.

I can't wait for the time to come...sure, solid axle might be "real" for now, but the "soon to come" evolution of the full scale trucks will show what a true performance gain independant suspension can provide.

I've owned an ESP modded Juggernaut, which I wisely traded in for an E-Maxx...I'd rather pull my E-Maxx by a shoe string than run the Jugg.

I'm eager to learn what the motors/esc are like out of the Twin Force...they could be an upgrade or at least another electrical option for our E-Maxxs. Besides, that's all I'd ever consider using from a Kyosho vehicle anyway.

I personally think they're 1/10th scale vehicles and Monster Trucks are junk (the MEGA FORCE is a prime example of that), and I don't know what niche they're trying to fill with this Twin Force...it will NEVER run with an E-Maxx on the track, and I doubt it will even make a good crawler. They must have a lot of left over parts from all the unsold Mad Forces, and decided to throw some batteries at it and see what happens.

I must be having a bad day...sorry to rant on about it...it's just my opinion...take it or leave it I guess.

Later...

Bigfoot has already jumped a 727!! I can't imagine something that weighs 10,000 lbs jumping much farther. :)

WOW! What a nice find! That's another "want" to the 2004 list.:D

I suppose you could shoot a monster truck into space by hanging it off of the shuttle, but the landing would be pretty rough! Ha!

[R3VoLuTiOn]

not if u get those imex guys to make real 1:1 scale jumbo tires for it:D those would be massive.

[BriS]

Here is an updated picture and more info.
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGAJ3&P=7

[BCat125]

Wow looks awesome. I cant wait to see one of these things run in person. It looks like it could be a pretty good rock crawler if it was set up right.

[JohnnyShore]

"REQUIRES: Radio: 2-channel with 1 standard servo, and 1 high-torque servo forsteering
Radio Batteries:
Speed Control: Electronic, capable of handling dual motors
Battery: Two 6-cell 7.2V flat packs with standard connector
Charger: AC/DC timed or peak for 6-cell battery
Paint:
Misc. Items: Building and track equipment"


:eek: Ouch...$299 without any electronics and I have to supply an ESC that can handle dual motors?!?! No thank you.

You're looking at at least $90-$100 for a Super Rooster or EVX, and another $50-$300 for a radio system. I was thinking maybe for $300-$350 including electronics I'd consider one, just as something to beat the snot out of. Unless that price comes down, I predict it's gonna be a major flop.

I do understand that a lot of people want to put their own electronics in these trucks, and I have an FM in my E-Maxx, but there are a lot of people that buy Monster Trucks because they're RTR, and that's where these companies are making their bread and butter.

I'll be keepin' my E-Maxx, thanks.

Later.

[Performance RC]

It comes with 550 motors. They got teh good tires on it now.

But what is this?

Radio: 2-channel with 1 standard servo, and 1 high-torque servo for steering


Why do you need 2 servos?

Battery: Two 6-cell 7.2V flat packs with standard connector

Its going to need an EVX

[4wdmt]

i think the standard servo is for the mechanical speed control IF it is included in this KIT. i also do think its a little bit pricey without the electronics. i hope the price will still go down.

[BriS]

I know it is not as good of a deal as an E-maxx, but it is cheaper than a TXT-1. We'll have to see what it is like when it comes out. Maybe the other servo is to shift the trans if it has more than 1 speed, but I guess that would require a 3 channel radio.

[Tamiya4ever]

Could be a typo :D

[samyman]

nice monster truck, solid axle rocks.not good for racing,unless you got a so low cg.but good for real scale rock crawling.

[4wdmt]

check out the "paint scheme" this mt has at tower hobbies picture - its wicked!

[Hairball]

I'm guessing no one has any off body pics yet?

I've got a Mad Force, so I'm really interested in this Twin Force thing... :)

[RrR]

My USA-1(electric) beats E-maxxies at my track all day long.The only time I was beat was by a Brushless Maxx.

[guver]

Could this thing have the 3-speed trans?

[DCLXVI]

I'd be interessted to know if it is going to be using the Magnetic Mayhems or if Kyosho are planning to relese another 550 motor...

[BCat125]

Those motors shown on the website dont look like magnetic meyhams. They say X speed on them.

[DCLXVI]

That is true...interessting...hope they will have different winding than the MM...on the other hand, it is probably 14,4 volt motors...

Question...how much of your USA-1 is stock? I'm betting you've got the stock gearboxes filled with Thorp gears and outdrives, a Sassy Chassis, and aftermarket suspension and shocks, right? So really, it's probably not a "true" USA-1 anymore...no stock USA-1 would ever be able to run with a stock E-Maxx. I suppose they COULD be made competitive with enough $$ and time, but what can't?

95% of winning races is driving ability in my opinion, which is why I can beat most of the guys at my local off road track running their souped up 2.5 t-maxx's with my old .15 pro t-maxx.

Unfortunately for about 2 months I did own a Hi-Rider Corvette (2wd USA-1) back in the early 90's, and the stock dogbones only last about 10 runs before the little nubs wear off, and let's not talk about the stock suspension. At that time my Dad had an old Royal Crusher, and he'd whoop me like a red headed step child on the 4th of july!

Seriously though, I'm glad you find enjoyment in running your truck...as said earlier in the forum, beauty is in the eye of the beholder. There isn't much that's more fun that beating people with old and "outdated" equipment. Makes'em feel real bad!

Hey, next time your in the Twin Cities area, e-mail me and bring your "USA-1" up to my club's track, and we'll run'em and see what happens!

Later!

[RrR]

My USA-1 is all stock but the chassis,EVX and MonsterMaxx motors

[huasze]

obviously a truck with the evx(which belongs to the e-maxx!) and faster motors like monster maxx ones would beat stock e-maxxes in speed! with a rolls-royce airplane engine, a car made in Siberia could outrun a Ferrari anyday!

[JohnnyShore]

You got a pic of your USA-1 you can post on here?

I seriously can't imagine how the stock drivetrain can hold up to 14.4volts and Monster Maxxes.....you must have to replace the bones and drive cups every other day....

[TweakedTad]

I broke every stock bone I ever put in my a-1 without even trying. I like my A-1's but they are very weak trucks wish they had spent more time on them would have been a nice truck.

I hope the Twin Force is alot stronger. I will find out soon enough.

Tad Then you had some thing wrong.The A-1 is a hard truck to work on right.:)

[TweakedTad]

I find it funny that you are the only person I have ever read about that doesn't break the stock bones.

As far as mine being wrong I don't belive it was. I built the truck sat it on the ground pulled the trigger it snapped one on each end. I built aluminum ones then striped the outter axles. I am not bashing the A-1 but it is far from a good truck stock it takes alot of work to make it worth having.

Tad

[BriS]

RrR, do you have your tires glued? How high of gearing are you running. The stock axles are JUNK. They twist up and break way too easy. I have multiple broken stock dogbones laying around from before I switched over the the Traxxas stampede shafts. And that is from running the stock Magnetic Mayhems and 6 - cells. I love my USA-1 truck now, but it took a lot of work to get it how it should be.

[Wizardman_1]

I wonder if u could just wire the motors in series on the twin force so u can use a regular esc and run the batteries in parallel to get a really long run time. Or do the batteries and motors both in parallel so u could have power and still have enough time to have some extra fun. Is the twin force a kit you build?

[RrR]

I read about broke stock bones all the time its just not happened to me. I dont know why.I run them hard pull hole shots.But I do use lots on lube and stock length oil shocks. Heck I was told the gear boxs and ever thing would fly apart the first time I pulled the trigger.That was 5 or 6 months ago.

[RrR]

Tower Hobbies moved the date to Mid Jan

[JonBoy]

Anyone have a pic of there usa-1? I have one on the way to me. I am not sure if I made a mistake or not but traded a RTR stampede for one. It's just a roller but has 2 sets of tires and different shocks. The pede wasnt anything special traxxas radio and ESC and pretty much stock with a few minor problems. Also sugestions on things to look for when I get it would be helpfull. List of must do hopups would also be helpfull. Thanks Everyone

[BriS]

The usa-1 can be a good truck with some work. Upgrade the axles to a style like sassy chassis used to make, use 1 piece hinge pins for the lower control arms, a different chassis will greatly help steering options and a longer wheelbase helps the handling. Thorp gears and differentials would almost make your drivetrain bullet proof, but they are hard to come by, keep an eye on ebay for them. Go to RCPic.net and do a search for usa-1. There are some pictures of my truck as well as others.

[Nitroaddict]

I think this thread is supposed to be about the Twin Force, stop filling it up with babble about the USA-1

[BriS]

:rolleyes: Since when has any of these actually stayed completely on the same topic? Besides, until the truck actually comes out there really isn't anything else to say about it.

[guver]

How about telling about the transmission??
How many speeds??

[2.0dohc]

its a single speed

[BCat125]

Thats stupid that it is only a single speed.

I was going to get one but my hobby shop called the distributer and they said it wouldnt be in until april.

[BriS]

its a single speed
Where did you find that info?

[BriS]

Towerhobbies lists the Twinforce in stock. RCCA, if you haven't got one of these yet, hurry up and do a review on it. We have been in suspense long enough.:D

[4wdmt]

feb. issue of RCCA have the TF in it. but only in a one page AD. anyone have one yet? a personal review will be nice :) .

[Tamiya4ever]

What does the picture of it look like? Does it have the body off?

[4wdmt]

they just showed the TF running in the dirt, not much info though. you might even mistake it for a mad force if not for the body and whats written in the ad. hhhmmm, they didnt picture the TF standing up in the air doing wheelies. just wondering if it can pull wheelies from standstill.

[NIC]

Hi !

I got a precopy of the Kyosho 2004 catalog and in it are pictures and info about the TwinForce.

Here are a few infos:

*Singlespeed
*Twin X-speed 550 motors
*Slipperclutch
*14,4 volts
*New "milder" caster angle
*Pretty heavy at 4500 grams

I´m sorry I don´t have a digitalcamera so I could post pictures, but I´ll try to explain.

The packs are as you might have seen mounted on their side and on the "outside" of the chassie. Then the motors are on each side of the spurgear (offcoarse) and the motorshaft are at the same hight as the spurgear-shaft. The pinions look like they are 48p and 19 or 20T.
On top of the motors are a plastic box with the esc and receiver in it. It is locked by a bodyclip.

I wonder if there are room under the motors to mount some cooling fins to the motors because like they are now they are pretty much blocked by the esc-box. I think it´s easy for the motors to build up heat when they are coverd like that.

Anyways it looks pretty good I think.

NIC

[twisted]

well the tf is out,my hobbyshop has one and i plan on getting it tommorrow.might be a lay-away.no rush as we have 2 foot of snow anyhow.

[Tamiya4ever]

Sounds pretty cool. I remember seeing a picture earlier and noticed that the packs were on each side. Did you see anything else interesting in the 04 catalog? :D

[NIC]

Tamaiya4ever, some news could be find there.

MadForce in a readyset, a new sized indoorcar called "@12" wich is powerd by 8 AA batteries. Madforce in MiniZ size, the FW05R and offcoarse the Kanai 3. A small indoor helicopter and a .21 engine powered boat to name a few.

NIC

[RrR]

Well I got builted today!! You can use 17t-20t pinion gears The spur is 50t.It has a oneway bearing to the front axle. And you can drive it the wall and it will pull its self up and flip over. and the tires are soft and sticky

[Tamiya4ever]

Hmmm this truck sounds great. Can you make it go in reverse with the one way? And can you make it 4wheel steering?

[Tamiya4ever]

Thanks hankster. The truck looks pretty durable. I noticed on TowerHobbies that they have a few hopups for it out, just some gears and a special chassis out so far. One thing about solid axle trucks is that they are easier to clean. No arms to take apart :D

[hankster]

Yeah, it seems real easy to work on. 4 screws and the center "diff" is apart. Also, for those that haven't read, it uses a "one-way" going to the front axle on the center "diff" and not a normal diff like in the E-Maxx. One must have will be the TI steering linkage... it's real long and those steel 4-40 rods won't last long.

[Tamiya4ever]

Whats the T1 steering linkage? :confused:

[hankster]

TI = I as in the letter and not 1 as in the number. TI is short for Titanium.

[Tamiya4ever]

I seen the steering set at tower. I am thinking of getting one. I was thinking of a nitro truck, but I like the ease of electric. :D

[hankster]

While I have not run the truck yet (still waiting for the ESC to come in) I can almost bet that there will be problems with the linkage bending.

As another note: If anyone gets this kit, use 35 weight oil in the shocks. Oil is included with the kit but I didn't try the included oil as I've never found high quality oil to be included with a kit.

Tower has the Mad Force upgraded linkage kit, I am sure that it will fit the Twin-Force. You can basicly use all the Mad-Force hopups for the Twin-Force except for the engine. :D

[hankster]

Turnbuckle trick? Not sure what you mean.

While the Mad Force parts may fit (I haven't tried) Kyosho does have linkage bagged for the twin Force (part #MAW009). Also available from Kyosho are hard aluminum polished side plates, aluminum steering cranks, big bore shocks and different gears for the front and rear diff.

[StevePond]

Tamiya4ever - there are a couple nice things about the front one-way. Yes, you can use reverse, but it's rear wheel drive only. The one-way provides very responsive steering, plus it really makes it easier to control the truck in the air. If you're nose down, you can hit the throttle and bring the nose up quite easily. Applying too much brakes while most trucks are in the air, usually causes the truck to flip over forward on its lid and usually will break things rather efficiently. :D The front one-way of the Twin Force eliminates the front wheels from the equation, so the reaction to stabbing the brakes isn't nearly as violent.


We ran the truck and it's a pretty stout performer. It kicks back on the wheelie bar almost instantly and you can ride it for as long as you have a straight stretch of road. It's also got very good speed. Someone made the comment that it should have a two speed, but there are two reasons that's totally unnecessary: electric motors have linear torque delivery, so there's little to no advantage in having a 2-speed. Second is, an automatic shifting two speed needs a one-way bearing, and without a mechanical brake like we have on the nitro version, there would be no braking. A mechanically shifted two-speed is the only viable option, but I don't think it helps performance. It's more important for the people that want to say "... and it has a two-speed transmission" than it is for performance.

Overall it's a really nice truck. I'll leave the final analysis to Kevin because he's doing the full test, but it's a pretty strong performer based on what I've seen.

[Tamiya4ever]

Thanks Steve. I think that I am going to go ahead and get this truck. I and allot of others was wondering if there would be a electric version of the Mad Force since we don't do nitro. Its good that Kyosho brought it out. :D

[BriS]

Do you know what issue the review will be in and are there plans for videos?
Here are some I found from Kyosho's web site.

Did you see any new electric touring cars? I head that Kyosho has one, and a new 4wheel drive buggy.

[twisted]

the turnbuckle trick is done by using four turnbuckles off a tmaxx.you put the turnbuckles on the plastic links off the axle on the madforce. this prevents "axle wrap" and the dog bone being popped out. also helps the suspension ears not being broke off on hard landings off of jumps.seeing how kyosho has addressed these problems i dont see the need but was wondering what you guys thought.

[Tamiya4ever]

I think that New Era had some links to do that with. Did you guys check out the video if it? It handles pretty good, and did not flip over one time after those jumps.

[Tamiya4ever]

I just found out that the Twin Force comes with 2 different hubs, one for the stock rims, and another for guess what............T-Maxx rims. :D

[twisted]

ya, it comes with aluminum hexxes that fit the maxx size rim or you can slide over the maxx hexxes a plastic hax to fit the tf rims. sweet.

i think tho you will need maxx offset rims.

[Tamiya4ever]

I wonder what it would look like with some big joes. :)

The TF is a very tuff truck I been running for two weeks with an EVX and two 7 cell batterys.I play very hard only thing broke is the rims.The steering is holding up great long rods and all.One more thing I whent to my LHS. the check out T/E-Maxx tires and thay will fit the stock TF.rims....

[Tamiya4ever]

Hey that sounds great. What is the runtimes like?

[Viperrgh2]

:D this truck looks sweet once I get some spare cash this is my next rc definatly!

[Viperrgh2]

Steve can you make a thread for this truck in the kyosho forum?? plz

fast ?

[twisted]

ok lets put it this way,compare the speed to a stock emaxx runing the same gear.

[shadowghost1]

Wonder what its Crawling ability is?

[twisted]

not that good. the two link design doesnt allow for much articulation.

[T-Force1]

Hi all,
Just got a Twin force a couple of weeks ago. Let the upgrades begin!!! Here is my improved wheelie bar (I hope... first time trying to attach an image):

[T-Force1]

Hmmm... where is everybody?

Anyway... I have determined that the Twin Force has a significantly longer runtime, given the same batteries, than the E-Maxx. (I own an E-Maxx as well). The motors and ESC are much cooler than the E-Maxx as well.

I have not done an official speed test, but based on running along side another RC truck, the Twin Force seems to have the same top speed as an E-Maxx (w. the same battery packs).

My 6 cell Sanyo 2400s give me wheelies on demand. I did a continuous wheelie for a couple hundred feet down my street. I am glad I replaced the little plastic disks with my new setup... they probably would have been ground down by now!

[nascar3]

I agree I had 2 emaxxes and now have a twinforce with an evx and orion matched 3000 cells. I get about 15 min of runtime. Silly wheelies and the truck is just as fast as the emaxx in second gear. Motors and esc run much cooler. Will post some pics later.

[Cildein]

I was thinking about getting the twin force and did some research on the suspension upgrades. Why not put a piviot joint (like emaxx turnbuckle) where the plasitc arm meets the body frame? Would that not increas articualtion? would it make the suspension unstable? All they have there now is a solid screw that allows it to piviot up and down? I am just brain storming here to help improve my choice.

Here is a link to point out the area I am talking about. Right below the batteries.

http://www.kyosho.com/cars/kyoc0103-suspension-2.jpg

Any input would be appreciated. No spelling comments!:p

[T-Force1]

The stock design does have a screw that only pivots up and down. However, the "arms" twist, which provides some of the spring action in the suspension. The articulation is actually better than it looks like it would be in the pics because the "arms" do twist. The straight axle actually does pivot (left wheel rises, right wheel lowers or opposite).

[Cildein]

Good to hear it has more than it seems but would the idea of haveing a piviting join there allow for more travel? I guess I would love the idea of it being able to reach TXT-1 abilities with such mods.

I don't however want to start redesigning the whole thing. Thanks.

[T-Force1]

Here is a pic of it's articulation. It only has another 1/4 of an inch more than shown here though... (and I get to show off my paint job!) That's a soda can by the way. I'm not really sure if pivoting joints would help or not. I'll have to think about that. There is an absolute stop going up and the shock extension going down. Might have to change those as well...

[Crash104936221]

anyone else looking into 4link setups yet?

T-Force1 thats a sweet paint job there!!!!

Twin Force, EVX and Hobbico CS-80 servo (334in-oz), 4link on the way
Evader ST, 17Tx1 SG2, S3010 Servo, EZX-R Pro ESC, RPM Starz wheels, ProLine Striker II tires

[plumbronco]

I increased the suspension travel on my Twin Force by removing the steel pivot points and installing two plastic bushings per arm that I got at the local hardware store. Here is a link to the dimensions.
It is cheap and gains you quite abit more travel.
http://hometown.aol.com/plumbronco/myhomepage/index.html

[T-Force1]

I might try that plumbronco.

I have two other bits of info for twin force owners:
1) Traxxas makes a 94mm titanium turnbuckle which is an exact fit for the steering link between the left and right wheels on the twin force. I didn't necessarily want it for titanium (they make a steel one too), but it has left and right hand threads with a place to grab and turn it, unlike the Kyosho stock one with both ends RH threads. Now I can adjust my toe-in easily.
2) The rear diff was assembled incorrectly from the factory in my kit. When I got it, it felt really rough turning it. When I took it apart, I found one of the shims had been installed on the wrong side!

[Cildein]

Anyone know if it will be possible to get 4wheel steering for the Twin Force? How difficult will it be?

[plumbronco]

I wonder if a guy could use the New Era axle mounted setup on the rear of the truck to achieve four wheel steering?
Link to New Era steering setup. (http://www.neweramodels.com/cgi-bin/item.cgi?session_id=meucjxhugmaswcbfeiyptggnfjwptm iq&part_id=1378)

[T-Force1]

I can't really see how they mounted that servo tray to the bumper. If it were placed on the rear without modification, the diff MIGHT interfere with the action. If the tray can be moved to the other side of the bumper, no prob. Gettin kinda expensive though... $69 x 2 + $40(?) x 2 :eek:

Also, the twin force is a little tipsy in turns at higher speed. 4WS would probably make that much worse. I don't do much climbing though. I always wanted to come up with a speed sensitive 4WS, but that would be a lot of work and testing!

[Cildein]

Anyone know where I could get a Twin force really cheap, besides auctions. My LHS says they would beat any price I found on the web!

Thanks!

[Cildein]

Ok guys I need to know how much I can mod this baby to get max torque! I have 13T 32pitch pinions on my emaxx and was wondering if it would fit on the twin force? Also would I be able to change the spur?

[twisted]

you can change the spur and pinions but believe me this truck already has to much torque with the stock gearing.

[Cildein]

I could not help but notice that the Twin Force might be able to house a large servo like Hobbico CS-80? It would appear that there are two bars across the chassis that the servo mounts to. If you where to move one of the bars or both would it be possible without major mod, just a little drilling and die the threads? :confused:

The Hobbico CS-80 does 275oz of torque and only costs $25 so this would be well worth the mod. ;)

[twisted]

i dont see whay it wouldnt fit with a little modding.

will it work YES!!!! :D im useing that servo i just drilled 2 new holes for the rear bar and 1 new hole in each bar soi could use all 4 servo mounting screws

only problem is that the suspention bottoms out on the servo horn i would guess that i have lost the last 1/5 ot 1/6 of the suspention travel, im going to move the servo ontop of the bars and see if that gats me some more travel


im not sure What ESC you use but a EVX will not power the CS-80 i would suggest a Rx pack for the servo/Rx and let the sticks power just the motors

your lucky if it will power a hi torque standard size IMO, i 100% regret buying the EVX, it was a waste of cash. i asy was becuse it falied after only 25 or so runs, when it failed it was one dry, inside the eled box, and it was not hot

Joe
Twin Force, Hobbico CS-80 servo (at 7.2V im guessing over 375in-oz :D ), Sprint ESC way over loaded but its tuffin it out wet or dry!

[Cildein]

Let me know if moving the servo to the top works. I have a RX pack because I don't like how the EVX only supplies 4.8v. Well needless to say that is a much better alternative for buying servos!

[Cildein]

So I have heard about the new Johnson motors for $3.50 that perform under the kyosho but more than the titans. However what was interesting is apparently if you use the EVX with the kyosho motors you could burn up the EVX when reversing? :eek: Is there a solution to this? lower pinions for less motor strain? :confused:

[BloodClod]

I notice that the chain is very tight on my new TWINFORCE. So much so that even when I tried running in the tranny with a 540 motor the chain got heated up after a few minutes.

Is this normal? I've had older chain drive vehicles before and normally there is decent slack in the chain for the tranny to run quite smoothly. Could other TF owners please share their experiences?

Thanks in advance.

[Revival]

Hi BloodClod

Yup its very tight in the beginning......I just gotten my TF but I have not build it yet....but I'll take it that it would be identical to the MF which I have. I dont remember the chain getting hot though. Perhaps you may want to check if the chain is rubbing on to the spur housing or that it is not aligned properly.

After afew runs, it will 'stretch'......

[Apero]

I have never owned a RC car (real one) and I am waiting my TF to arrive in Finland. I might be among the first Finns to be able to drive it.

I have tried to find reviews about the car, but there are not any. Q: What ESC you recommend for that car, ´cos I think shop from where I order it forgot ESC totally...

I paid goods and have "starter kit" 3000mAh 6-cell battery (another will come with the body), charger and radio kit, but the rest of the "ready set" will come late May, waiting... I hate sellers who will sell you "everything you need to run it", but misses part that seems to be one of the most important.. :mad: , now my budjet gets over and wife will not be happy.

Still I would like to hear comments about TF, just to calm my mind and support the idea of a good purchase ;).

It is single speed and has no reverse or brakes, how it stops, and how fast? Might be a silly question but I do not understand how 4500g car which drives 30-50km/h could be driven without brakes???

Apero

Ps. Do you have any videos of TwinForce, one´s at the Kyosho site I already have. Salesperson told me that it will go nearly 50km/h with 2 3000mAh 6-cell batteries, well might not happen... If you are interested in there is a downloadable manual for TwinForce in pdf-format at Kyosho site.

[Apero]

They have some new ESC, which cannot be found from catalogs..., we'll see later how it works.

Q: Any idea of runtime with 2 3000mAh 6 cells batteries?

Apero

[BloodClod]

Thanks for the info! :)

Maiden run today - was really good fun. Didn't try anything too crazy yet but I am impressed with the TFs speed, acceleration and overall handling. It's good for a MT this size. Downside would be the rearwheel braking and reversing. I guess I can't have the one-way bearing to improve handling but get 4WS braking/reverse too... lol!

[KLEAR]

The Twin Force does not have Braking, nor reverse?

[BloodClod]

It does not have 4-wheel braking and reverse. Only the 2 rear wheels brake and reverse.

[KLEAR]

It does not have 4-wheel braking and reverse. Only the 2 rear wheels brake and reverse.
Ok, Thanks :)

[Apero]

New for me also, thx. I did not get the package this week, waiting for a new shipment coming on next week.. Reverse and brake, even in one end is a good plus, from sellers speach I got the wrong idea, thanks for correcting ;).

Apero

[Apero]

I mean there are only few comercial videos out there, so do you have your own? Just to see what TF really is like, in use... Speed, jumping etc..

Apero

[4wdmt]

question guys. whats the difference of the E-Maxx Titan motors to the TF monster motors? are the pinion shafts lenghts the same? hows the performance of the motors with EVX or SR? thank you for any input.

[BloodClod]

I haven't taken any vids of the TF yet but it has good torque and speed with the stock motors. I think 50kmh is a bit of a stretch though. Most tests (by the mags) clock about 20-21mph so I'd say probably 30+kmh is more likely.

Ran the truck with some of my crawler buddies last weekend and on Monday two of them placed an order with the LHS! :)

As for the motors, there is little visible difference between the Titans and the TF motors. Both look identical in dimensions, and the TF motors also have the same cooling fan design. Of course, even most 540 motors look the same... could be a world of difference inside the motors.

The stock foams that come with the truck are wierd though... they are only half the width of the tires. I didn't like how that worked so I put in a set of Monster Pirate foams I had and they fit like a glove.

[4wdmt]

thanks bloodclod. is it true that TF 550s are 27 turns while the titans are 23? 27t is much more torquer, right?

[BloodClod]

I've still had no luck finding out the winding of the motors - the search continues.

I thought I'd bring this thread to the top with some pics of my truck.

Here's just a shell I threw on from my old project... the new shell is still unpainted... hope I get time to finish it tonight.

[Apero]

Nice pics and a good story on your site. You have installed some protection for a "chain"?

Is you suspension so flexible, because you mod chassis or would that articulation be possible with the stock chassis also?

Looks so nice... We will be waiting for new news of your project :).

Apero

[Apero]

OK, got my esc today and had a test run.
550 motors are 19 turns, and my esc is made by Kyosho (model NO. KA-6) with brake and reverse, runs well but more tests must be made.

Apero

[badtodabone]

hi i need a link or a part number for every part needed to make a complete axle. thanks :)

[BigBoy]

How does the Twin Force compare to an E-Maxx?

[DRdave]

APERO how is that ESC. from kyosho (ka-6) working out? I was looking at the specs. between the EVX,KA-6 and the super rooster and the later two seem much better.

[hyperstang]

Well..

A couple of guys at our MOD CLOD races bought over 2 twin forces and these things look fun as HECK. I am really considering getting one...In fact, really considering it. Just looking at what is posted and some pics.

Its faster than the Clods at it was insane fast. I think this would be the emaxx competitor. I currently own a XC2 Clod with Thunder Tech bottom Links and running D5 8x1 in mine. But this thing kicked the CRAP out of my clod. Looks more fun also.

Well, I'll be reading posts and I just put my Clod for sale at our local shop. The person in charge says if there are at least 2 more twin forces that show up, then he will open a class for them to run also...

I'll let everyone know if I own one real soon....HECK Christmas is around the corner...

Race on.....

[guver]

I just put together a twin detonator and am very dissapointed, It's the slowest vehicle I've driven.....

Twin force is going to be my next truck, I have a evx and batts and radio for it already.

[hyperstang]

After what I've been reading, I am more in tune to getting one now. Just need to sell that clod and some other monster truck stuff...

Race on...

[MicroDiladum]

Anyone know where I could get a Twin force really cheap, besides auctions. My LHS says they would beat any price I found on the web!

Thanks!

Tower hobbies is selling them right now for 229.99. Thats pretty cheap. They also have there discount code thing going that knocks of another $20. I dont know if your hobby shop will honor that extra $20 though.

[always_opencarb]

is the twin force any good?

[guver]

I'm going to find out over winter or right after winter. It will be dual batts with the stock motors or titans

[guver]

blood clod are those stock batt trays?

[ncrego]

Yeah, always_opencarb, the TF is a good truck. I'm very happy with mine. It's pretty much tough as nails, and nice and light, so it jumps, handles, and accelerates well. Mine is stock except for the body, and gettign rid of my eMaxx to get it was one of the best decisions I've ever made. I work across from a skate park, and everytime I took the eMaxx out there, it came back broken, I've yet to break the TF. The only weak part on the TF is the rear pinion/bevel gear setup. And it's not that it's weak, but that it's factory assembled, and not shimmed properly, so it'll strip. So, when you get one, before you run it, open up the axles and take the play out of the setup. I also didnt like the one way bearing on the front driveshaft, so I swapped it out as well. Other than that, it's stock, and it rocks.

And Guver, those are the stock battery trays.

[guver]

thanks, they look good. I'm looking for a nice tray like that but holds 8 cells. In plastic of course.

[Slapnut]

Hey folks - just got my TwinForce today(wow - a lot bigger than my Baja King).Just a question about the esc though.They've sold me the super rooster, however the specs for it only list 12 volts max input and my understanding is that I'm gonna need something that handles 14.4v. So can anyone tell me if this is gonna work or do I need to get an EVX, Novak Super Duty XR or something else.Looks as though wiring the SR could be messy too.

Thanks in advance.

[guver]

I would try it, but the evx is a perfect esc for it.

When over volting esc the bec circuit is usually the thing to mess up. You could wire it up so that only 1 battery goes to bec , but both go to the motor plug.

[Slapnut]

thanks guver,

i'll try getting hold of an evx i think - its gonna be much simpler to install.If i can't get hold of one soon enough, i'll try fiddling with the wiring on the SR.

[guver]

I just ordered my twin force. I plan a evx and a 100 oz servo (will it be enough)
and 12 cells stock motors or 21 or 19 turn motors. for now.

Merry Christmas, Guver that's all I got myself.

[raptorridr660r]

Well I have decided to get an electric truck for the first time to ass to the collection. I am very interested in the Twin Force. I wanted to get an emaxx, but having had a tmaxx in the past, it makes hard to get a emaxx, that and everyone has one.. I have also had interest in crawling. To me the twin force looks to the the perfect inbetween truck to fill the gap between the emaxx and something like the txt-1. I see Tower now has them listed at $209 with a $20 off code. Its very tempting to order it, but is there a better place to order from, or is that the lowest they can be found at? So far tower is the only place I have seen them. Also this will be my first hobby quality electric, other then messing with my brothers stampede, what would be a good setup for esc and batts to give me long run times and decent speed with the stock motors? I don't need blinding speed by any means, I have a 1/8 buggy and savage for the speed thing. This will be more to play around with my brother and his pede and when I don't wanna tote all my nitro stuff out. I already have 2 nice radios so I am good there. Any input would be greatly appriciated guys....

by the way, lets see some more pics from you guys that have Twins already..:)

[guver]

what's that code number?

[raptorridr660r]

its on towers main page, there are 12 numbers, more off depending on what you spend. Where did you order from and what was the price if you don't mind telling.

[hyperstang]

I just ordered my TWIN FORCE today and should be arriving by this Thursday for Friday.

Can't wait to get this thing together and slap in my D5 10x1 motors. Put my clod on the side and I am ready to go with this bad boy..

Race on...

[guver]

its on towers main page, there are 12 numbers, more off depending on what you spend. Where did you order from and what was the price if you don't mind telling.

I ordered from tower and it was $209
I guess I better get mine together.....
EVX , mtronic super e-truck,Kyosho Perfex KA-6 also would be good.

Hyper, it's not good to use 540 motors is it?

[hyperstang]

Wow!!!

What size motors fit in this bad boy???

thanks

[guver]

Any will fit, but it uses 550 size. I just think that 540 will not live very long.

[docman2]

Ive got one coming this week also. Got it with a gift certificate I got for Xmas.

You shouldnt have a problem running 540's in it. Just dont run them at 14.4v. I run 2 Kyosho 17turns in my Emaxx at 7.2v and its faster and runs longer than the stock setup. I used to run a Super Rooster with the batts and motors in parallel but then I switch to 2 super Roosters. Each is setup with one batt running to one esc to one motor. Its kind of overkill but it runs a little faster and longer than the single ESC.

[docman2]

Well I got mine in. I think Im going to go ahead and take the diffs apart to fill them with oil before building the truck. Anyone tried different weight oils yet? Im debating what weight(s) Im going to go with.
It looks like a fairly easy build. Very low parts count compared to a lot of trucks.

[guver]

I just got mine together, looks good. Now I just have to learn how to paint bodies....

It seems faster than e-maxx, I have yet to really let it rip thoguh cuz of snow. It wheelies too much.

[Slapnut]

Well heres mine

http://www.arach.net.au/~penn/twinforce8.JPG

Now all i need is my esc so I can run it.

[ncrego]

DocMan, definitely take the diffs apart, mine were shimmed so poorly from the factory that the rear stripped in a pack and a half. Since shimming the diffs, and filling them with fluid (I used 10k front and rear, and took the one way out of the front) I've been very happy with it, and haven't broken a thing in months. The only advice I have is to put another locknut on top to the stock nut that holds the arms to the chassis of the truck. I was never able to keep them on and tight until I did that to lock them in.

[guver]

Is anyone using the kyosho perfex esc? If so how do you like it on how many cells?

[hyperstang]

Just got mine in yesterday and am almost done getting it together. I am going to use the Kyosho motors until my Novak Brushless arrives. Will post pics when I am done with it...

Can't wait to show up at the next Clod Monster Truck event...

Race on...

[hyperstang]

Well.....

Here is my Twin Force. I decided to put in my D5 10x1 motors and have a "Y" harness for the batteries running off a Super Rooster.

Took this bad boy for a spin and I was very impressed with the top speed, but I am lacking low end big time. I will tighten the slipper all the way in, what is the lowest gearing that the Twin Force can go and what pitch are the pinions??

Anyway, here are some pics of the new addition to my monster trucks...

http://img.photobucket.com/albums/v280/TritonDRIFT/twinforce.jpg

Got the Ford Truck body from my Mod Clod and will probably use this until I get the new F150 body and Novak Brushless....

http://img.photobucket.com/albums/v280/TritonDRIFT/twinforce2.jpg

[guver]

I think the d-5's will not hold up very well. You running low volts or high?

[hyperstang]

Okay....Okay...

Got your point, 540's is not the way to go with this truck, only 550's.

I may switch to the Kyosho's, but not right now.

Race on...

[guver]

Your truck looks good, I wish I could paint. I have mine running with a streak so far. Can't take it outside it is too wet.

[hyperstang]

Thanks Guver,
Actually, I am not a detailed painter myself. I am a solid color racer. The color I use is white on all of my cars. Not becuase I want to be different, but actually everywhere I race, especially off road, all the trucks are dark colors. I just need that color so that I can find my car in a pile up on the track..LOL..I also like white.

Race on....

[docman2]

540 motors is not the problem. Its the fact they are 10x1's. Thats way to low of a turn motor to run. You need to run 17 turns. I ran the 14 turns in my Emaxx and they were a little faster but you lose the torque and kill the runtime.
Im guessing you have the batts and Y-harness wired so your getting 7.2 volts to the motors? If so thats right and the 540's will hold up fine but switch to the Kyosho 17 turn motors. They have the fat comm and 5mmX5mm brushes that give great torque and hold up really well. The gears are 48 "metric" pitch so you need the Kyosho pinion gears. A standard 48 pitch wont work. Go with the 20 tooth Kyosho gears, part number MAW050-20, with the 17turn motors and you will get good torque, speed, and runtime.

[guver]

10 turn motor would hold up fine if it was geared properly and the voltage wasn't over 8 volts.

[docman2]

Didnt say a 10turn wouldnt hold up. Its just to low of a turn motor to run in a MT. It dosnt have the torque you need. You would have to go with a 25-27 tooth pinion to gear it correctly and I dont think they will fit. A 17t motor with a 20t pinion will give plenty of torque and speed. Plus the batteries will last longer. Like I said before I tried 14T motors and there was only a small increase of speed but It really killed run time.

[metalry101]

Hey guys! Great to see that there are so many other people who run the Twin Force! Here's what mine currently runs...

Novak Super Duty XR ESC
Hitec 645MG steering servo
JR XR2 radio
Kyosho 550 motors w/ associated heat sinks
22/whatever stock is gearing
Machined steel rear ring and pinion (instead of that cast aluminum junk)

I love my truck, but I have had a fair amount of problems w/ it...most notably the center dogbones bending due to control arm flex on rough landings...

I wanna try my Novak HV Brushless system in it sometimes...but I'll wait a while. My E-Maxx is enjoying that craziness at the moment.

[guver]

Hi, metalry,

Which is faster (in stock form)? e-maxx or twin force.

I just was able to run mine first time. Pretty impressed so far as I have the motors split for breakin. Too bad of weather here.....

[guver]

I am really considering that perfex esc, anyone have any thoguhts on it?

[hyperstang]

Thanks for the imput guys. I know gearing is a big time factor, but I'll work with what I got right now. I just ordered my HV Novak Brushless from Towers using the $25 off coupon. Should be here by next week Monday and I'll install it next week.

Can't Wait...


Race on...

[metalry101]

I'd say they're about even probably..maybe w/ the slight edge going to the Maxx the way I had it set up. I was running the Kyosho motors in both trucks, w/ 22/whatever stock is gearing on the Twin Force, and 22/64 gearing on the Maxx (w/ a ton of other mods as well)...and the Maxx SCREAMED w/ that setup. I haven't really tested it much at all w/ the BL system yet, as I keep breaking things. I screwed up second gear, so I gotta replace some stuff inside the tranny (after 3 years of abuse it finally starts to wear out a bit).

[Thunder VP]

The Twin Force accually uses 32 pitch pinions like the E-Maxx,TXT-1 and Clodbusters do. 540 motors can also be used very successfully when the correct gearing is used. The gear ratio is almost exactly the same as a Clodbuster and it uses 2 540 motors. I run 2 Twin Forces one with 14T motors and 14 tooth pinions.(28:1) The other has 12T motors and 13 tooth pinions (30:1) (the smallest that will fit also) I run with an 8 cell pack and its faster than it was with stock 550s on 12 cells. Its also lighter making it accellerate faster and still have good run times. (about 6 mins on 1700s) If you try to run any 540 motor with pinions larger than 16Tooth you will not get much speed and run times will be very low with motors and bats getting very hot.

I'm in Australia and just got a price for the Novak brushless system through a dealer here - almost died - $785au .(the truck cost $450au here)
So I'm thinking mail order from Tower.
Has anyone gone from using the 2x 550s to a brushless ? - how big was the improvement ? I may just need to go with the Super Duty XR ESC so I don't blow my budget.

I tried it out yesterday. Pulled the Super Duty XR and 550's out and slapped in the HV BL. Daaaamn. It was MUCH faster. To run the Novak BL you have to pull the heatsink off of the motor, as it doesn't even come close to fitting between the chassis rails w/ it on there. It's worth the bit of strain though, as it's crazy fast. Definately worth the extra bit of money. That said, if you do determine that it's just too much money, the Super Duty XR is a helluva nice speed control. It's much better sealed against water and mud and whatnot than the EVX. I've taken my Twin Force in the mud w/ that ESC on there and haven't had any problems. It stayed pretty dry (I don't run the radio box, the ESC gets mounted on the steering servo cross braces so it's exposed to air and whatnot). No problems though, just very expensive. For an extra 120 bux U.S. (at least at my hobby shop), the BL is definately the way to go, but the Super Duty is sweet.

[hyperstang]

this past Sunday, a friend of mine and myself decided to see how long our Twin Forces with Novak HV BL in it can jump. We took out the roller blade ramps and put it on the pavement. We managed to jump 5 parking stalls, but a bad landing took me out early. I bent the front drive shaft and two jump later, my friend bent the same thing.

Good thing, he owns a hobby shop and got the parts coming in 2 days, bad thing is that it ended our run. So we started drifting with the sedans and busted out the airsoft guns.

Here are a couple of pics of the Novak installed..

I opted to install the FAN, we run on pavement and can get some crazy top speed and I don't want the ESC to get to hot.

Like Metarly said..its MUCH DAMN FASTER. I beat a REVO off the start and beat it until it shifted into second.....

Hi guys,

thought you might like some more action pics of the TF showing off it's jumping ability. :)

Easily 8-9 feet of air. :)

My mod chassis is designed to allow stock battery trays or alternatively, to run a 8-cell pack with 540 motors. Here's a refresher pic without the stock battery trays.

[metalry101]

Righteous pics man! Looks like a blast! I like your chassis, that's ultra-sweet.

[Slapnut]

Thanks Metalry & Hyperstang - sounds like I should get the brushless setup now.I'll probably end up wanting more grunt later - so Ill save money in the long run.
I only used my truck twice before the esc melted and that was just before Christmas - I'm getting anxious.

[starluckrc]

I've set up a few Brushless Twins and had a pretty big power gain. Even my slower 10L was good for over 35mph on 12 average cells. I'll have to try my new $235 system this weekend.

$235 bux for an non-Novak BL system? What are you running?

[hyperstang]

Yeah..what are you running? You aint running the Novak, I can't even get them at cost for that amount.....

[Slapnut]

Hey chaps - I'm gonna order my brushless setup from Towers -as I am in Australia, I thought I may aswell get some spares over while I'm at it.

So what bits have you all managed to break so far !! ?
Anyone noticed much wear on gears/sprockets(particuarly with BL setups) ?

(hyperstang - the front driveshaft you bent - I take it that it is the one from the centre of the truck to the front axle(IF143) ?)

[hyperstang]

Yes..

that is the one. It only broke becuase of a poor landing and not the BL system. As far as anything stripping gears, pinions...NONE AT ALL!!!!

The TWIN FORCE was built to handle and I can vouch that it does. My replacement part has arrived and I am just waiting on my PROLINE F650 body to come in. I really enjoy this truck and have put it through alot. I hope that I can try some dirt mounds when the truck gets fixed. Keep all you posted..

RACE ON!!!

[Slapnut]

Going through testing now. Available for delivery in April.

[slid'in sideway]

Just got my Twin Force, but before I start putting it together I just thought I might ask what are the best parts, modifications I could put in it before I build it?
All answers will be greatly appreciated.
Thanks
slid'in sideway

[metalry101]

Upgrade the rear diff. The cast aluminum ring and pinion is a damn joke. The machined steel setup is like 60 or 70 bux, but it's worth it.

[slid'in sideway]

Metlary101,
Thanks for the quick reply. That will be the first thing I do. I kind of figured that the parts for this truck would be expensive, I remember the hop up parts for my old electric USA-1 were expensive, too.
Back then we used to those things against clods. Has anyone tried to race the Twin Force?
Thanks

[Slapnut]

Well my hv-maxx arrived from Towers today - now I can finally use this thing after it sitting on the shelf for 3 months.Ended up costing me under $400 Australian - which is half the price I was quoted from shops over here - so I'm happy.

Now to get this badboy up and running - mainly on the rear wheels from what I'm hearing.

[Slapnut]

Well the fun didn't last long. I've already chewed the rear diff, although I reckon perhaps it wasn't assembled correctly out of the factory.Fortunately I had ordered a spare one with my brushless order so I've put that in.

Has anyone had to put the shim(that sits next tio the carrier bearing) on the oppposite side?. I found that the crownwheel/pinion would start to bind up and try to jump a gear when I assembled it as the manual said to.However when I put the shim on the other side(RH) the gears mesh smoothly.
Think I'll need to order a couple of the steel diffs.

[crazy-rc]

what do you guys think of the truck i am thinking of geting one?
if you would not mind posting pic i would rally like that thanx

[Slapnut]

crazy-rc

I like the truck - I was looking for a bit of a basher and I think they do the job well.They are a nice basic design with fewer moving parts compared tio something with independant suspension - which in my opinion means theres' less to break, however handling at high speed isn't gonna be a strongpoint for them -mine tends to get a little bouncy.
The diffs appear to be a bit of a weak point - and going brushless - as I have - tends to compound the problem.There are factory upgrades available though.The suspension arms tend to flex a bit too - whether this is going to cause problems in the long run though, I'm not sure.Once again though, there are aftermarket options to fix this too.
They are really the only weaknesses I have noticed so far. I spent almost a day hillclimbing with this thing - which involved a lot of it tumbling back down the hill - and all I had to show for it was a scratched up shell. So apart from the diff problems, it's everything I hoped it would be
- plus it does sick wheelies.

[crazy-rc]

thanx is it really as big as tehy say it is. on a scale 1-10 how hard is the kit to bild. i have really never realy olny bild an x-cell and i want to get in to monster trucks they look like alot of fun. if you would not mind posting pic.

[Slapnut]

Its a pretty easy kit to build - the axles are assembled by the factory which cuts down build time.On your scale I'd say its a 5 - from memory my tamiya baja king was more fiddly to put together.
It pretty big, bigger than my mates e-maxx and as big as a number of nitro trucks.
Heres a photo of it next to a beer(also - check earlier in the thread for more photos from some of the other folks)

does the kit come with motors?

[metalry101]

Dude...don't quote when you don't need to...

Now, to answer your question, yes the kit comes with the motors.

[crazy-rc]

how fast does the the TF go with brushless?
with a brushless is it over powered?

[metalry101]

Depends on gearing, what BL system, what cells, how many cells, etc. With the Novak system on stock gearing and 12 cells you could probably expect 35ish. Maybe a little less. You could probably see 40 with taller gearing and 14 cells. As for whether or not that's overpowered...well...that's a relative question. If you're blasting it up and down the street then no...if you do crawling then yes. It really depends on what you plan to do with the truck. If it's too fast for what you're doing you can always exercise throttle control and just not drive it WOT.

[crazy-rc]

thanx i am a guy that likes to bash and blast over the crap cars :D

[ineed2selmycars]

how does this truck compare to the Emaxx.. or other electrick 4x4's? sorry if its been posted before but i'm lazy :D

[metalry101]

It's different. Not necessarily worse, not necessarily better. I had a Twin Force a little while back and I want another one. I've had my E-Maxx for 3 or 4 years now (can't remember which). The E-Maxx certainly handles better and is arguably a little tougher, but the Twin Force is unique, and definately a lot of fun. It wheelies like crazy and is super simple, which is a bonus. I don't think either truck is necessarily better than the other, as it's more of a personal preference and usage type thing. Obviously racers don't buy Twin Forces, but they're good bashers, and they're a blast.

[crazy-rc]

does any one have any vids?
what are some good hop ups?
were do u get them?
how does it handle big jumps?

[EPHELI]

video's= workin' on it
hop ups= even lots from other mt's will work
tower hobbies =$219.99
i launched it from my garage roof=flat on all fours witch in turn=no stupid t/e-maxx bulkheads to replace!!!

my tf is all bl, lipoly, digi servo powered.
dont skimp go ALL out and its a bullet proof mt and mine is travelling at about 42mph now so its NOT slow!!

[starluckrc]

Cool.....another BL Lipoly Twin Force. Gotta get a hardened rear diff gear setup, then I'll be back in action.

[guver]

Hmm, too rich for my wallett.... I just stripped out the front diff gears. I figured the rears would be first. They look aluminum.

[metalry101]

They are, that's why they suck. I know the hardened steel setup is pricy, but it's also bulletproof. Cast aluminum ring and pinion gears are a joke.

[Haruchai]

This may be a silly question, but I can't seem to find the answer anywhere. Since I see that a few of you own the TF I know I can count on ya!

Are the solid axles plastic or metal? If they are plastic, how well do they hold up? I haven't heard anyone say anything about them, and was wondering.

Thanks!

Metal...

[metalry101]

The housings are plastic. The drive axles that are housed in them are metal.

[Haruchai]

Thanks!

So, do they hold up pretty well? It doesn't look like the truck has much ground clearance, and according to the Kyosho site it's only about 2" or so. Do the axles get hung up on objects much?

[metalry101]

Depends where you're driving. It would high center ocassionally if I was driving through some deep runs or something with, but short of that I didn't have any problems.

As for the strength, I wouldn't suggest hitting things hard with it, because the knuckles on the end of the axles (a seperate piece) don't take to impacts real well, but they're not fragile. They just don't have anywhere to go. If you hit them hard they're going to break. Other than that...I didn't encounter any problems with them.

[guver]

The gears do not hold up well from what I have heard and experienced.

[Haruchai]

What about the Twin Force Spirit? Has anyone heard anything about it? Other than the chassis plates being lighter, is there any other difference? Would that 100 grams weight savings really change much? It's less than half a pound....

By the way, I know I'm bombarding you guys with questions. Thanks for taking the time to answer them! I really like the Twin Force, and am very interested in getting one. I'm just trying to get as much information as I can from the people who actually own one of these models.

[metalry101]

I don't know about any other differences, but I haven't really looked into it at all to be honest. Yes, 100 grams (roughly 3.5 ounces) will make a big difference. Every little bit helps, and despite the utter simplicity of the truck, it actually is quite heavy.

[twinforce144]

how do you fix that

[metalry101]

How do you fix what?

[guver]

I finally got my gears put in, I forgot how much fun it was to go on two wheels. If I can't get parts for this twin I am going to sell it w/ evx and a new TQ body and 2pl radio.

How much should I ask for it? Is there a online place to get all parts for kyosho? I wouild like to keep it, but I waited over 2 months for parts..

[metalry101]

Not yet. Parts should be available in the next coupla weeks. If you're selling it LMK, I might be interested in picking another one up.

[guver]

I just got done increasing cell count and will run it tomorrow. It is set up almost like my e-maxx now.

I have been on that kyosho america, but cannot seem to find a parts section.

[metalry101]

Your LHS should be able to get parts in the next few weeks, either through Kyosho directly or through HRP. I searched HRP today while I was at work and they're increasing their selection of Kyosho stuff in a hurry, which means Kyosho America is finally getting stuff from Japan.

[egress123]

I just got back from Japan and got this Twin force package with ball bearings, two x-speed motors, and ESC. total price was about $350.

I don't think I have seen this package in U.S. yet. how about you guys?

[guver]

I saw the spirit, it had a perfex ka-6 esc. But I am not seeing much from Kyosho, still waiting on a spur gear.

[metalry101]

Guver~
Are you getting your stuff straight from Kyosho or through HRP?

[guver]

I am still waiting, as I haven't yet found a dealer that can get parts. I just called 3 of my lhs and they said a "few more weeks" I just need a spur gear and then I am selling the twin force.

[metalry101]

Would you sell it before you get the spur? If so, how much?

[guver]

I have it for sale right now without any electronics for $159

[egress123]

I just finished building Twin Force. but there is no where in the instruction that tells me to apply lubricant for the gears. is that OK to run the car without lubricant?

[metalry101]

The diffs are prebuilt and pre-lubed from the factory. The rest of the gears on the truck (there are only 5 other gears, if you want to count chain sprockets as gears) don't need to be lubed. If you lubed them, they'd just attract dirt, so don't worry about it. Besides, they're designed to run dry, so it shouldn't be a problem.

[kurrz]

Anyone still run their Twin Force. Also does any body know where I can get one? Thanks
