Recently appearing on the Yokomo Japan website is news of a new shaft-drive touring car. The "SD SSG Special" version of the MR-4TC is certainly sporting a driveshaft, and it appears to include the unique woven graphite originally seen in use on the Yokomo YRX12WE 1/12-scale car. The car will be available in late March in Japan, but there's no information as to when it will be available in the States. More information should be available soon.

Your tripping. Thats all Yokomo right there. In fact, its so much nicer looking that a tc3 the associated guys are probably puking their guts out trying to figure out what they are going to do to compete! I'm sold! It will be mine! I've been bitter, sitting around waiting for something exiting to happen in the touring car world for far to long. (No, the new hpi aint doing it) My XXX-S is rolling off the bench in jelousy! (maybe I can still get rid of it on ebay before everyone finds out about this new Yokomo!)

So I take it you're a Yokomo fan.... ;) :D

If I can be the voice of reason...

Yes, it's got a shaft down the center of the car, and it's going to have a ring and pinion gear in each differential. For that matter, it could even be Associated's differential assembly given the close relationship between these two companies in the past. The point is, not too many people know much more than what is seen here, so there's no sense speculating - lets just wait until we get more details. There's a limit to how much you can make a shaft-drive car look different, especially for the sake of avoiding the inevitable "it's a copy of (fill in the blank)." Would you go so far as to make the car less efficient and less competitive by moving stuff around enough to simply have the appearance of being different? Of course not. So let cooler heads prevail here and lets just say it's a Yokomo. After all, we know who brought shaft drive to RC...

Tamiya! ;) :D

I'll be getting one at the end of this month. Gonna cost me though. To me, it just looks like a Yokomo Special with a shaft drive. Also with what was said about their close relationship with AE... I wouldn't be surprised if the diffs were the same. Yok does make the "better" oneway for the TC3 and NTC3. Anyways, we'll see at the end of this month...

LoL, agreed. Go Tamiya!

It wouldnt be such a bad thing having AE tranny stuff in the Yok. Associated tranny are among the best out there. It'll be easy to get parts for the it if that is the case.

Yes I guess I am a yokomo fan. My mr4tc pro was my favorite car for a long time. I rushed into getting a XXX-S when they first came out an I have been whinning about it ever since. My friend I sold my yokomo to is still lovin' it and won't sell it back to me...:mad:

To those that think it's a TC3 with SSG, or a Special with a shaft, I can tell from the picture alone that the car is 95% new.

Apart from the shaft transmission, the wishbones are new (with droop screws), the way they are mounted is new, the front hub carriers and uprights are new, the shocks are a further update (with the built in bladder kit). I reckon the only parts that will be carried over from previous yokes are the steering bellcranks, and turnbuckles. I would expect Yokomo to have their own diffs and crown wheels in there as well (since they use metric size bearings).

Dino the great

03-03-2003, 09:14 PM

I wish they would include a front ball diff as an option because one-way diffs don't work well on some tight tracks. I know that alot of people use one way diffs but they should include both kinds in the kit as a setup option.

yet another attempt to compete with the old tc3 shaft system. i can't beleve how many people are jumping on the shaft drive band wagon. do you think thay are creating there version because thay came up with the idea just now. heck no!!!!! thay are sick of gettig stomped in the electric touring car racing. i will bet my left arm you will see a losi shaft drive in the next few months, years. everyone baging on the tc3 is switching over to some form of shaft drive just after thay where saying belts are the only way to go all i can do is laugh.

You are tripping, too. The reason we like this car is because its YOKOMO! The tc3 never exited me to much. The shaft drive is cool but they were not the first ones to do it. The steering assembly could have stayed on the design table a little longer. And.... well you get the idea. YOKOMO!

Think of it this way...How many different ways are there to design a single shaft car? Not many therefore they are all going to look very similar. That does not necessarily mean that they are copies...only similar. Also keep in mind (for the AE nuts) that the TC3 did not originate the shaft drive system in a TC...the 10th Tech Predator was running a very similar designed shaft before that...and before the Predator, Tamiya was running shaft cars...not sure if Kyosho ever did.

Anyway...It's a nice looking car...Still waiting for a saddle pack shaft drive car though...

How can so many people assume that this car is so much better than any other shaft driven TC from pictures alone?? In my humble, humble opinion......It'll be just like any horribly balanced car (with batteries on one side, electronics on the other) with torque steer problems. It seems that there hasn't been a truly innovative design since the Hpi Pro 3, Kyosho KX-1, Rc Lab 7 6.0 etc. Granted, some of these cars aren't the best out there. But those companies tried something new and didn't just make cute copies of an aging, but competent design. Instead of having many different cars to choose from, we'll soon have 10 different multi-colored TC3 knock offs buzzing around our tracks!!!

RCBuddha

03-07-2003, 12:13 PM

I like the car. While the electronics placement is the same as the TC3, to me, its an all new car. If you try to make the argument that this is a tc3 copy, well, the tenth tech was out before the tc3, and it was shaft. HPI is going to produce a shaft drive, and I know from the racing circles here in CA, that they are designing the suspension to be similar in geometry to the TC3.

Besides, haven't you noticed that belt drive cars all look similar, e.g., the ta04 looks strikingly similar to the Rs4, the 414 looks similar to the Xray, xxx-s is simlar to the kx-one; they both have belts. and on and on and on......

My point is this: There are only so many ways to do either a shaft or a belt design. There are only so many ways for you to lay out the electronics. Of course cars are going to look the same, just look at the typical 4 door family sedan.....they are all starting to look the same!

jay272:
I really don't see how a car laid out with the batteries on one side is "unbalanced". If you PROPERLY use the MIP tweak station and setup guages to balance and setup your car, there is virtually no torque steer issues. In addition, a competent designer can almost eliminate torque steer issues in their designs. Torque steer is present in shaft drive cars, i'm not denying that, but in electric racing, its not going to be noticeable to most r/c racers.

this tc stuff has really taken off in the last few years. although we have plenty of cars to choose from, (in my mind) there's only been two chassis that has really stood out to me: the tenth tech predator, and the new tamiya f1. these cars have true pushrod suspensions that mimic full size cars. imagine...an rc car that functions with full size physics.

very well said,i personally dont want a bad handling car that looks innovative and has unique placed motor and battery just to be different at the track yes the layout looks lile the tc3 but there are WAY more factors to a car handling than the battery and motor layout!!the yokomo seems one sweet ride:cool:

Ever seen a XXX-S?

Nice Yoke though.

03-08-2003, 10:53 AM

i believe jay did not mention the xxx-s because the single belt drive-train was first used on the kx-one(im not a historian so i might be wrong, but i know that the kyosho came out before the losi). I could be wrong of course and they just forgot it.

JKA

03-08-2003, 11:41 PM

If the XXX-S inovation stopped at the single belt drive train I wouldn't have felt inclined point out Jay's oversight.

But no matter... this thread is about a Yokomo... and a mighty fine one I might add.

Possumbot

03-09-2003, 10:56 AM

i'm not saying losi's innovation on the xxx-s ended at the drive train, but considering there has been a lengthy discussion about belt and shaft drive it was a logical place to draw a line. But your right, this thread is about the new yoke, and i'd go for it, if it wasn't for the fact in the year i've spent in bethlehem i've never seen a yokomo or a part for one, and my driving style doesn't agree with straight lines and not hitting things. But at any rate, the car looks great.

JKA

03-09-2003, 02:27 PM

I think that could be the biggest obstacle for this and many other really good cars (XRay)... the parts availability can be slim. Plus they need a better showing at world and national events. Like it or not thats what many racers look at.

Exactly - who's going to buy a Yokomo - I mean, it's not as if they've won six off-road world championships, and several on-road championships, including the 2000 On-road worlds, and the 2002 12th scale, is it?

Why do so many people argue about anything new that comes out? The Monster GT uses the SAME tranny as the tmaxx, and build on the same idea BIG NITRO monster truck... it has to start somewhere to get better. Heck, I dont' want to say it b/c i love the TC3 but the yokomo MIGHT be better. We dont' know yet. Nobody around has drivin one. Why judge negativly on pics? it looks like a great car to me. Lets not talk originality here.

03-12-2003, 05:50 AM

Indeed I've had heard about an all new Yok something like 8 months ago, and considering the release of the SSG MR4-TC, I was wondering whether that was the new Yok or not...

If you have a look at the specs, you'll notice that the car is designed to be very easy to maintain, with a few different spares : all arms are the same, same gear cases, symmetrical front steering blocks and rear hub carriers... Now that's very RARE.

Also, only 4 screws to maintain diffs (like the TA 04 or XXX-S), possibility to remove suspension arms without removing arm mounts, easy removal of spur gear...

Now this car seems to be a REAL racing machine, made to facilitate the racer's life. Also, with the long development realised on it (who would say no looking at the engineering work made on it ?) I'm sure it handles very well, just like all Yokomo cars.

Just my 0.02 € :D

I've noticed one thing they could have done. I noticed only room for six cells. I would think to really have more adjustibility they would use a 7th opening as a front to rear weight bias adjustment like the XXX-S.
I did notice the angled stick pack holder. That should help some as far as the difficulty of stick pack slippage.
I like Yokomo stuff. My YZ is still running fast and well even with the upgrades for it. The only gripe I have here in the states is Yokomo part avaliability. I don't know why they never continued the 4WD Off Road program here. It's gotten better now with the interest in TC, but still is somewhat a problem.
As far as the TC3 goes. We have a lot of guys racing them here. But the fastest guys are running the XXX-SG. The XXX-S drives a little more on the edge so you have to have a smooth driver. If you do, he will eat just about any other guy out there. Most XXX-S's don't finish because of driver error and overdriving the car. It doesn't let you know how close to the edge you are without suddenly breaking the edge and traction.
BTW, not one guy here runs a Yokomo so far. This car might change that.

The spec sheet reads like a tuners wish list. My personal favourite is the steering block height adjustment! The only options required would be C-hubs for the caster (even Yokomo hasn't found a way around that issue).

The attention to detail is outstanding: outdrive savers, super fast diff access, etc.

Kudos to Yokomo, you guys have delivered the merchandise. When can I get one?

SpeedtechRC has tons of spare parts for the car. So that is never a problem.

Plus you can order from shops in Japan. It's actually cheaper this way. Shipping is 5day and about $15!! They deliver on Sundays too!! Plus you get the low price on parts, not jacked up prices that don't match the Yen Rate. Or order from Hong Kong. Same deal. Order Shipping by EMS.

Anyhow, I enjoy my 2 SD's. I have tons of parts already for it as well. So far I'm the only Yokomo at the local tracks. But more are on the way. I was also the only Tamiya at the local tracks until a friend bought one. :D

Randman

05-12-2003, 04:03 PM

I have read over this whole thread, and see that the only problem people seem to have with this car is that it looks like a TC3. Well honestly, if I was an RC Car company, I would look at what's winning out there, and the TC3 is obviously doing that, so why not take their design, and improve upon it. Now if you look at this car, and the TC3, you will see that many changes were made, you have a flat ssg chassis, with a stiffener, and upper deck. It might just be bad memory, but I can't remember an upper deck on a TC3... I think the gearboxes actually resemble a 1/8 buggy more than the TC3, 4 bolts and your diff is out, sounds similar to my Kanai 2. Identical arms right and left, front and rear, that is a huge plus over the TC3, you would only need to buy 1 set of spare arms rather than a set for front and rear. Look at how much more adjustable the castor blocks and hub carriers are, notice that as you go further out on the hub, the roll center raises as well, that is there for very fine tuning, and I think the idea is great. I have owned 4 TC3's in the past, and my MR4-TC SD SSG will be here tomorrow, can't be sure, but it looks like with the technology put into this car, it is going to own the TC3 as well.

Now to the people that own the car, is there any certain weak point you have found on the car yet? I am planning on getting the graphite servo saver parts for it, titanium nitride shock shafts, and need to find somewhere that sells good ceramic bearings in metric sizes, but what spares should I pick up for this thing?

JimmyMac

05-12-2003, 10:58 PM

Well I have 2 of these cars. Spares I have are of course A-Arms. But I also have one diff case. Hinge pins. Rear hubs and front spindles. Caster blocks. Arm mounts. Diff gear and oneway diff gear. Dog Bones. And outdrives. What I have broken so far was first a dog bone. Then 2 arms. And bent one hinge pin.

As for bearings, they aren't really a must as mine spins free'r and free'r after each use. I did have ceramics in my Evo3 though. And they were nice. Acer Racing will have a ceramic bearing set in June I believe.

Weak points I would say are the dog bones. Would be nice to have a wide bumper like the RPM one for the TC3. But we'll see if one is made in due time. Arms tend to fall in there as with most cars.

Shocks are excellent quality. As well as the rest of the kit. No dremeling of the diff cases needed like on the TC3. Electronics mounting can be a hassle if you don't run the lastest and greatest electronics. This is due to the small amount of room for electronics. Easy spur changes only can happen with certain spur sizes. And it's not as easy as said, but it's not hard either. Just need patience to play around with the pins in the shafts for alignment.

Car drives real good. Seems to me that Rear droop plays a big role in setup. I dunno, might be just me. But the car likes to spin around if not set correctly. Car accelerates very quickly. And it's quieter than a TC3. Although it did seem noisey with 48 pitch when I tried them out. I run 102 and 112 spurs. 112 spurs helps me space the motor out more for side to side balance of the car. I also think that the 112 is the largest spur that you can run. Maybe a 113 might fit.

I dunno, I'm sure there is more. Just can't think right now. But it is a good kit. And it's very pleasant to look at!!

Randman

05-12-2003, 11:34 PM

I am planning on a 100 spur, with a 32 pinion on an 8 double Reedy Krypton motor. That gives the car a 7.34 drive ratio, and should be a good start. I can't wait till I get the car and get to start playing around with it, and figuring how it all works together. Going to get the aluminum universal driveshafts for stock racing, trying to keep the car's rotating mass and resistance to a minimum. I was actually planning on getting all of those spares you listed that you had, so I guess I'm in good condition so far.

JimmyMac

05-13-2003, 11:42 PM

I run aluminum bones in the rear and steel up front. Aluminum bones seem to bend very very easy up front with small impacts. I'll more than likely switch to titanium up front next month. Square makes them. Other than that, I'm doin pretty good with the car.

Kilruf - interesting to see you mention the cars tendency to loop the rear end around - that's the handling trait I'm working on curing at the moment. The car is great when you keep the momentum up, but if you have to lift off a bit too much (for example in traffic), it seems to want to break the rear loose a bit too much. I still haven't found the ideal settings (so far I've only made the car worse!).

I would say the weaknesses in my opinion are that the front shock settings need a lot of adjustment from the instructions to get the right travel for slick tyres.

Other than that, the quick release spur isn't as quick as you think, and the driveshafts are a real pain to slide out of the diffs when you take the car apart.

The transmission is silent though, and the car does carry really good corner speed, I can turn inside anything and come out well ahead.

I haven't broken anything (although I stripped my servo gears, probably an over-tight servo saver), but my track uses fairly soft barriers.

I have never heard of the company Square, do you have a URL for them? Titanium is a little bit lighter than steel, so I could run that in front and aluminum in back like you plan on doing. The car didn't come yesterday, so it better be here today, I can't stand waiting. Is anyone running a 5'th body mount on the upper deck somewhere?

JimmyMac

Sosidge, you running stock or mod? If stock, I can shoot you over my setup. To cure the hook around... take some droop out the rear. I also found tires played a major role in hook around too! I kept hooking around with CS27s... ended up goin to CS22's and problem solved. Same with Rear Droop... I run 5.5 right now in the rear. I measure Rear droop from the lowest part hanging down whether it be the hub or a-arm. In front I measure from the lowest part too except the Kingpin. Do you have a bunch of Yokomo Tuning springs? Anyways, let me know Stock or Mod and maybe I can let you try my setup.

Square is a Japanese company. They do have a stateside website. But they don't have SD parts yet on there. I order from rainbowten in Japan. Parts are cheaper from them and shipping is 5 days or less. They deliver on Saturdays and Sundays too! Only like $15 for shipping!! But I also order from SpeedtechRC. Steve Wang does great business and is a good guy. I'd suggest ordering from him any day!

As for 5th body mount.... not yet. Been working on setup. But I might give that a try sooner or later.

Well here is the link to rainbowten. http://www.rainbowten.co.jp/english/

You'll have to go under Shopping, then Today's Stock List. Scroll down to Square and look up the descrips to see what they have in stock and make for the SD. Sorry no pictures. www.rchub.com also sells Square. But I don't think they have SD parts yet stateside.

As for oneways. That's all I run right now on the SD.

sosidge

05-15-2003, 06:06 AM

We run on pretty different surfaces - I race on slippy floors, very low grip, with minispike tyres, so slick setups won't fall directly on to my car. I'd like to know what springs and geometry you're running though, and if you could tell me your droop settings at the chassis that would help.

Currently I'm running Orange springs up front, Green at the rear, 40wt oil, 2 degree rear toe, 5mm front ride height with 2mm droop measured at the chassis (i.e. I can lift the car 2mm before the tyres leave the ground), 5.5mm rear ride height with 3mm droop, 2 degrees camber all round, everything else standard.

I'm going to experiment with slightly tighter diffs, and more or less droop all round next. I would also like to get more camber change as the suspension compresses, as this helped to stop my Pro 3 snapping out on the slippy surface, but that's not easy to achieve. I'm going to try spacers under the balljoints on the hubs to angle the link more. I'll also be trying more caster angle when the blocks come out, maybe I'll use more kickup in the short term.

So much to do, but so little track time!

Randman

05-15-2003, 11:25 AM

I'd start out by going to a bit softer spring, Orange and Green are really made for high traction surfaces...

sosidge

05-15-2003, 12:30 PM

The thing with slippy floors is that there is so little grip, the springing doesn't make a huge difference, it's the balance that's more important. I prefer a stiffer car because I find it more responsive around the tight, smooth tracks. Some people run with a softer car for a sensation of more grip, but I find them vague, you can sense the car rolling before it changes direction.

If you're unable to get the Square Ti bones.. try using MIP shinny cvd's in front and the aluminum version in the rears.

Tobee Craft will also be releasing a HD dog bone in Aluminum.

MR4TC Rear bones will work with the SD.

As for setup:

Front
Orange Spring
450wt
#3 piston
64mm long with long shock end (nub cut off.)
Out on tower.
3rd goin in on arm (standard)
Camber link on tower is Middle Row Middle Hole.
Carrier link is middle.
Lower hole on Caster Block.
Upper Sway bar with Gold bar.
Spacer. 2mm front of arm.. 1mm rear of arm.
1° toe out.
Droop 6mm (measured with ride height gauge with chassis flat on setup board. measuring lowest part of arm (not kingpin))
Oneway

Rear
Pink Spring
450wt
#3 piston
62mm long.
Out on tower.
3rd goin out on arm.
Camber link on tower is Lower Middle.
Hub is 3rd goin out.
Lower hole on Hub.
No sway bar.
Spacer. 1mm front of arm... 2mm rear of arm.
3° rear toe.
Droop 5.5mm
Diff half out.

102/35 Monster Stock

I think that's it. But for a slippery track... I think you should try softer springs with shocks laid in and no sway bars. Maybe a Pink front Yellow Rear with 30wt front and rear. Same ride height all around. longer camber links to allow more body roll. But only in the rear. If you do it up front... the car will want to hook around. Plus I'd run more droop.

Anyways, that's just what I think. Well let me head out.. getting late! :o

sosidge

05-16-2003, 07:44 AM

Well I'm going to have to do a lot of fiddling with the setup because the car was really inconsistent last night on a particularly slippy track. Softer springing wasn't really making much difference, nor did increasing toe. My gut feeling is that there needs to be more camber change during compression to keep a more even contact patch on the outside tyre. Seems to me that the car is great out of the box when grip is good, but I'm having troubles when grip is poor. All I've managed to do over the last few weeks is make the car worse!

Glad that MR-4TC dogbones will work, the MIP CVD's are only 25 bucks a pair at Sheldons Hobbies. I have a bundle of RC stuff on eBay right now, and it's up to just over $1500, with 3 days left to go, so when the auctions end, it's money I'm going to spend. I have a Turbo 35 GFX in my view, Hudy lathe, Quantum Competition, Reedy Kr motors (and a couple stock motors) and Reedy XCell 3300 packs. Big Dog (Jason Lutz) is going to do my scheme on a couple different bodies, going to try the Stratus 2.0, and the Volvo S60 to see which I like better. Acer Racing should have their bearing set avalible pretty soon, they had to make a new bearing size for our kit, that's why it is not yet avalible. This car is going to rock, SoCal Raceway's Pro Mod class is what I'm aiming to get into, but might practice a little bit in the Pro Stock.

cobra81li200

06-11-2003, 06:20 PM

Square driveshafts are definiitely an option to get, moreover if you use the front oneway, because the stock ones breaks in that case, even with a 17T (no problems with a front diff...).

I'm not going to get them for the moment as I have a front diff (plus they're out of stock), but I'm better getting the tobee F/R axles and main driveshaft, titanium screws (I already have the dogbones).

I raced the car on sunday, it was the first time I use it, and I won the 17T class (on my track). The car was as fast as my over hopped-up 414M SSG although everybody felt it could be really better (for most, this rear train problem, that appeared even more when I put a 12T...).

I'm going to race it again this week end, before going to the nationals at the end of the month (maybe that time I'll win, instead of being 2nd...).

JimmyMac

06-11-2003, 10:02 PM

Where are you from Cobra? Durham (Nationals) is one of my home tracks. If that's the Nationals you are refering to. I use the Square axles on the front of my Yok. So far soo good. Need to order some more for my other car. I also run the Yok Graphite shaft... Ti screws. Plus I took out the center stiffener for more flex. My car is 1515g right now. Might reinstall the stiffener to get a feel for it again. I tell ya.. Mod is hard to get the car to handle just right for this track. Anyways... babbling.. let me head out. Gotta clean off the car from todays practice....

cobra81li200

06-12-2003, 03:44 AM

Ooops, thought my personal informations were on date... I'm talking about the french nationals...

Yet, I didn't try anything with the stiffener, but I'm sure it will give the car some grip (it will be a little bit slower but really easier to drive, so you'll be able to be more regular, and regularity is one of the most important things).

3.are yokomo spares hard to get?

07-19-2003, 05:10 PM

As far as hop ups for the SD you dont really need any,SD vrs. FT..I have ran both cars and I think their are a few advantages that the SD has over the TC-3,I think the SD's chassis is more resistant to tweak than the TC-3's,The diffs are alot easier to get to on the SD.,All four lower arms are the same(any arm will work at any corner).On the cost,the SD and FT TC-3 are close(tc-3 cost less)As far as spare parts go its all about your hobby shop,If they sell the kit they can get the parts.Plus the Yokomo ssg graphite looks way trick.

I'm now missing a servo and trying to find out what is a good buy.

I notice on the last few pictures on the SSG, the dude had some red device sitting on top of his steering servo. What is it?

10-14-2003, 09:15 AM

hey peoples.
What do you think of the new rayspeed hopups for the yokomo (performance only. looks not included).
i see that they do not have a chassis stiffener anymore due to the new servo saver.

JimmyMac

10-14-2003, 06:32 PM

It's not due to the servo saver setup. It's because the chassis was designed for asphalt. And most asphalt racers take out their stiffener from the Stock SSG chassis anyways. And don't forget that the top deck is counter sunk. SSG is not. I would say the RaySpeed chassis setup is stiffer than SSG, but not as stiff as the Black kit.

Anyways, the RaySpeed hopups are pretty good and offer other tuning options. The chassis is a very nice setup and works awesome on asphalt. For carpet, it'll tweak too much. It would be better to run the Black kit or the new tub chassis when it comes out in a few months.

Any kind of standard size servo will do. But if you really need the space, mount your servo 90° from stock. If you still need space, mount it 90° and use a Futaba 9550 servo. It will give plenty of room. I even had it setup to use the Novak BL system with all electronics still mounted on the lower deck. I'll find a pic of my old setup and post it.

Yes, 2 new holes. Plus you need to cut the upper ear off the left side of the servo to fit under the center brace. Then either cut the top off a servo mount or use a Tamiya lower servo mount. If you ever get the new RaySpeed chassis, you don't need to cut the ear off. I'm not sure about the new tub chassis. But for the Black or SSG version, you need to cut it unless if you use Shoe Goo or servo tape to hold the servo in.

Maybe I'll post a pic of my current setup tomorrow. If you want, I can email you a pic (1600x1200) of how I mounted my servo 90° on a SSG chassis.

Great pics of your Yokomo chassis! I liked them so much that I have one coming from Speedtech, who seem like a great bunch of guys. I understand the that the silver and black chassis diffference is in stiffness: the silver looks great but is a bit more flexible, the black stiffer for hard-core competition. I opted for the beautiful silver, which will be fine for a parking lot coffee bar pilot like myself. I'll post my obsevations as it goes together, comparing it to my latest rides (TC3, KX-One, Sport 2, and OB4.....)

Hey lhistand,
Be sure to CA Glue the carbon in the battery holes and the motor openings and sand it to a good smooth. I've seen the edges of another YOKOMO cut right into the battery pack in a couple of bump and runs with other cars. Also some guy got major scratches from the opening for the motor.

Thanks for the advice, Hyperstang! Those edges are very sharp.

In got my car on the road today, also with the Novak SS Brushless System, and had a bad experience! The car was fast, and handled well right off the start, but I was testing it on a course in my driveway, and hit a steel stake (put in for winter to mark the driveway for snowplowing) at warp speed. It was very ugly. I lost the two lower suspension frames, and, believe it or not, broke the front bulkhead! The bulkhead looked to be indestructible. It should be back on the road in three days, as Speedtech has everything in stock. The parts are coming next day air, as I can't stand to see this beautiful car broken! Needless to say the stakes are now wrapped in foam rubber.

But yesterday, on the third day of trying, the Yoke came all together with adjustments to shock positioning, ride height, readjustment of the diffs, and reducing toe in. I set best times of the day, and for the first time I am happy with the car. It's finally accelerating and braking straight, and I'm sure I'll find more speed. I'm running the Novak Brushless system with a 27 tooth pinion, which seems to be about ideal for my driveway track.

This is one beautiful car, and access to the diffs is a dream. Today I love it!

When I go to get spur gears and pinions what should I get? 48 or 64 pitch?

sosidge

01-04-2004, 11:07 AM

The car comes with 48 pitch gears, you can fit 64 if you like.

chuckwagon123

01-04-2004, 12:07 PM

Is one pitch better then the other?

sosidge

01-04-2004, 12:10 PM

48 is a better all round choice, 64 offers more ratios and the POSSIBILTY of more efficiency, but it's smaller teeth make it hard to mesh so you're very unlikely to see any benefits.

chuckwagon123

01-06-2004, 06:52 AM

I am looking for some torque, would there be much of a diff between 9.69:1 to 9.20:1? The 64p can get to 9.69:1, would that maybe strip the gears if I had a 11x3 in it?

sosidge

01-06-2004, 12:50 PM

The gear ratio you run will have no impact on whether or not gears strip. A loose mesh will be the most likely cause of a problem, followed by an impact, and a tiny chance of too much motor power.

An 11-turn motor won't put much strain on the car.

You should be able to get very low ratios with 48dp, the SD will fit larger spurs, maybe 80 teeth or more, which will let you run very small pinions if you want a very low gear ratio. Although 9.2:1 is already pretty low for any motor.

You should be able to get ratios lower than 9.

The chassis supports between battery cells looks awful thin. Has anyone cracked the chassis there in a crash? Most other cars look like the battery cut outs are about 1/4 inch wide between cell, the MR-4TC chassis looks like it's only about 1/8 inch wide at the narrowist point between cells.

Hi, I have a SD-SSG and I am just about to take delivery of a novak ss brushless system, Can anyone guide me in the right direction for gearing?
the best info I can find is on the novak site that suggests 7:3:1
What spur + pinion gears would I need to acheive this ratio??

I currently run my SSG Yokomo in the Electric Mod Sedan Class with a Novak Brushless. But the stock gearing is way to high for the track I run on. My ESC run super hot. Although Novak states to stay within their ratio, depending on the track you race at, gear to the track and not the Novak ratio.

I think that the SSG comes with a 30 Pinion and a 70 Spur. The track I race at isn't all that big, so I need to gear down to about a 23 or a 24T pinion. I run 3 qualifying 10 min heats and 1 10min main. My ESC is cool to the touch after that hard run. Can't say the same for my battery packs though. My ratio is down in the 5's to 6's. Just my opinion.

Race on...

By the way, anyone can tell me how to change my servo to face sideways. Where do I drill or if you have any pics that would be cool.

Race on...again...

Nice pic MR4man. Makes me want to start running some elecs and spending my $$ of some loose cells like the ones you have. I believe I can start off with a pair of 3300s, a better charger, and then get a new car to run them in. Currently have a monster hp stock motor and spike esc. Whats the price for this Yok nowadays and a good BL system?

I just ordered some extra parts for my YOKOMO SSG sedan, I love this car. I beat Pro 4's and a couple of TC3's out there. I am the only one running this car and the only bad thing about it is the parts aren't carried by my local hobby shops. Havn't broken anything yet, just snipped the body mounts a bit to short, so I am stuck with running a saleen S7R until my body mounts come in from Speedtechrc.com

Hyperstang: My local circuit is quite bumpy and little bit dusty......... from your opinion: What piston hole and oil weight should I use ??

Some drivers suggest 3 holes piston with 50 weight oil all around. What is your opinion, man?

hyperstang

08-11-2004, 02:48 AM

I currently use two in the front and 3 in the back. I also use 40WT all around. I had to adjust to my track. I run my sedans with traction in the back, so my suspension in the back is a bit softer than my fronts.

Because your track is bumpy, I would probably run a bit on the soft side. You want your car to absorb the bumps not bounce with a stiff suspension. For the dusty part, I run nothing but sorex rubber tire. I run 40's in the front and 36's in the rear. Here in Hawaii, our track gets very hot and we actually need to shoot the track down with sugar water or soda to get the RC cars to actually hook up.

So far my Yokomo has made a name for itself at the track. I keep up, and out run some HPI Pro 4's and TC3's out there. Because the parts are bit scarce, I need to order online, but so far, only body mounts is on my list.

Keep us informed...

Why you change the chassis from SSG to CGM ?? :eek: Is it better handling now ?

hyperstang

08-13-2004, 02:39 AM

Actually, I was considering converting, but the CGM conversion is a bit much. Becuase the CGM is a tub type chassis, its able to with stand bumps and hits from other cars and not put the car way out of tweak. I've been bumped and hit a couple of roadrails in one heat, put the SSG on the Integy tweak board and my car was totaly off....

I also understand that the CGM is more stable chassis, no flex in the chassis. Also, there is more room for your electronics and the servo is placed sideways instead of the way it is on the SSG. But keep us informed on how it runs.

Race on...

vtl1180ny

08-13-2004, 03:55 AM

Why you change the chassis from SSG to CGM ?? Is it better handling now ?

Almost everything said above... I race on carpet and the flex was driving me up the wall, literally... On op of that, the main place I race at is extremely tight and you are constantly getting bumped so the tweak was unreal... No matter what I tried to do with the SSG chassis, I'd constantly have my battery fall out after any kind of hit...

Yes, the CGM is heavier but it's much more rigid... No more tweak... No more battery packs coming out... The SSG may be great for some, but not for me...

asw7576

08-13-2004, 04:12 AM

Ooo........ I see :) :)

Well, I haven't drive mine yet, but the battery fall out issue is good info, thanks man. I will do some mods to eliminate battery fall out problem.

It's really surprising that CGM is better chassis than SSG.

hyperstang

08-19-2004, 04:16 PM

If I'm not mistaken, isn't there a bar that goes across on the outside of the chassis next to the battery? Mine is there and I have never had my battery pop out before. My SSG gets banged up left and right and even sometimes becomes a target at the track (all in good fun though). Sometimes when I get stuck on the rails or flip over, my buddies with the PRO 4's come by to knock me off or knock me back onto my wheels, which not once have they accomplished that..LOL!!!

But my battery is still intact. I was using a 2 cell li poly flat pack at one time. What I did was using the open screw holes that held that battery bar, I velcrod the li poly pack onto a piece of plastic and screwd in the plastic using the holes meant for the bar. I got 7.4V with the poly and running a brushless, I didn't ever want to go back to the sport packs becuase this puts out more power and is way...way....way lighter than a standard sport pack. My SSG flew but I wasn't able to use that while running. Also its a bit expensive also...but a hella lot of power and fun...

By the way, my body posts from speedtech came in and I am no longer stuck with using my SALEEN S7R. Time to change bodies, my mustang is waiting to be painted..

Race on....

asw7576

08-20-2004, 01:47 AM

I remove the side battery bar because my battery is saddle pack. I shake the car violently last night to see the battery would pop off, fortunately the battery remain in place.

If you watch carefully, I added 2 aluminium posts (silver) for added security against lateral movement.

My car is ready now, I have LRP IPC V7.1 installed, Futaba HRS + S9451, and Stock Motor 27T.

asw7576

09-18-2004, 03:10 PM

thanks minijosh.

it's kawada tires microdude ( pull from yokomo yr4m special : 20mm tires )

BTW, actually I'm having some driving problems with my yokomo. With normal 26mm tires all around, the car would oversteer at tight corner and it can't go straight stable. The car has tendency to left and right during acceleration as well as during deceleration ( rear tires don't bite ? )

So in the mean time I have to use 20mm tires at the front to lessen front grip. The car is now okay and driveable on straight but I get understeering problem at tight corner as well as exiting under hard acceleration.

What do you suggest ?

I read through the entire thread and saw some interesting info on chasis setup, but I'm still trying to figure out what body, motor, tire inserts, and tires to run on an indoor carpet track with one long straight about 40' long (maybe more) and a lot of medium corners.

I'd like to start racing at my local track. They have:
1/10 6 cell stock
1/10 rookie (not sure what this is yet)
1/10 19 Turn

I'm thinking of using a Rayspeed Accord for the body and possibly the P2PK Pro for the stock class.

Anyone have any suggestions?

04-08-2005, 09:41 PM

I race on a prepped asphalt track or carpet. the exposed diffs are no problem for me. I can see the open diffs being a problem if you race on a carpark track. Sand could get into the diffs. but then this is no different for other open diff cars like the TA-04. Its best not to lube the diff gears so that sand does not stick to the gears.

The diff gears are normal plastic. I have a set of graphite gears waiting to go in if required. Here is a close up pic of the front diff, team suzuki ally steering hubs and centre drive cups

I just got myself a CGM for a great price on e-bay. I am intending to use it as an upgrade over my LOSI XXX-S RTR - (parts are already becoming a pain to get hold of). I just have one little problem - I cannot see any indoor carpet set-up sheets on the web. I'd like to know if anyone has any they can post on this forum, or a link. I drive indoors on carpet, which I think is fairly tight, I think it is fairly high grip as well.

I bought a yokomo sd cgm, and already have a losi xxx-s (long story).

Anyway, the yokomo whilst feeling safe and stable, just has no mid corner grip, or turn in - the losi just hammers it for corner turn in.

IS this a problem with the CGM? I find that nearly all the other cars at my club can turn in much better, I am having to kick the back out to get round tight bends - by which time everyone is passed me - on top of that mid corner grip ain't up to scratch.

is it a problem i have with set-up or is it the car?

Am I gonna have to go LCG, or revert to the Losi.

I may resirn to the fact the Yokomo is for outdoors only and the Losi indoors.

What do I do? :confused: :confused: :eek:
