Who is already working on next year's car?

[Mod Man]

I am planning on bringing my current CF car next year. But, I also have another design that I am planning to build and bring to next year's event (not telling what it is). ;)


So, who is already working on next year's car?

Already working/testing a monster truck for next year. Sure hope there is an East coast event.

Thank you,

[fasterthanspeed]

Ive decided Im going to just improve on my design.
Im making a completely new custom front end and Ikm installing a 3 speed tranny for better accelerartion.

[ajlovering12345]

I have the 3 motor car and will be improving the design and reliability and will have the 1/10th RRR as well. I'll be working on their performance over the next 12 months

Cheers

Watch the tyre diameter! The class rules for next year will be more strict focusing on tyres size and type.

[Promod]

Darn, I was going to build a slow touring car and call it a monster truck.

Seriously, very glad to see rules being made for the monster truck class. Large tires that stick outside the body lines are what makes a monster truck A MONSTER TRUCK. Can't wait to here what the rules are so my build can be finalized.

Here are the suggested rules so far

Open IC. Any or multiple engines with chassis length no more than 1m (40"). Gyros allowed

Scale IC. Any kit based car with no extensions to chasis width or length. Single engines up to .28 (Up from .21 to include the new fusion 3). Any commercially available body shell with added wings allowed. (Gyros? maybe only on open)

Open electric. Any or multiple electric motors with chasis length up to 1m (40")

Scale electric. Any kit based car with single motor of 540 can size (36mm x 55mm with 3.2mm shaft). No extensions to width or length. Any commercially available shell with added wings allowed (Gyros?)

Electric bikes (rules need to be defined)

IC bikes(rules need to be defined)

Monster trucks. Wheel dia to be withing certain limits. (Need to determine rules)

Any suggestions?

Yup,ordered carbon fiber panel,chassis is on paper.Most other equipment on hand,will start cutting the chassis in the next few weeks.;)
With any luck,will be there for the comp next year.

thats 3/5 the way to where i plan to be by next year, current gearing and 6s is about 50MPH, gearing is 19 pinion and 51spur. I eventually will go to 20-22/51-46 and 10s lipo

[racerrandy]

I picked up a e-maxx that I'm starting to work on. I'm gonna make a flat chassis to stretch the wheel base out, and keep the weight low. I was thinking of ditching the tranny and using a 1\8 scale type center diff. I was thinking about going duel traxxas brushlesswith lipo's. Just to see what can be done using all traxxas stuff. I know it won't be fastest, but just want to see what can be done.

I think any monster truck entry should have at least maxx sized wheels.

[ajlovering12345]

When we run the speed event in the UK next year we will have entries for Jet and Rocket cars but they will have their own catagory for speed. There are at least 2 people I know have jet cars and another guy seriously looking into a real speed car with a 40lb thrust jet shaped like the Blue Flame of Gary Gabelich under 40" long

Hi promod (fastpromod),

I bought the motors and controllers from you, but I still didn't get your good positive feedbacks. This is lutach (lutach24) btw at other forums LOL.

[parnelli97]

I'm testing a few custom built chassis, but unless there is an east coast event I doubt I can afford to travel. If I can pick up a sponsor I'll go.

[veegaa]

Hello,

I'm also working on my car, but I'm not sure if I'm going to participate that racing or not.

Here is the link of my car:

http://veegaa.blogspot.com/

[ajlovering12345]

Its running backwards????

LOL. But then Front wheel drive is the only way to go with 2wd

I got 89 mph today with my RRR

http://ziggy12345-myspeedattemptcar.blogspot.com/

[fasterthanspeed]

Hey tony my car ran pretty darn straight with rwd. The gy401 gyro helped out alot in that though. Where did you get that body also? I am also hoping to get the new front end complete this month, make a new chassis built (as the new frontend has different mounting holes and before the comp i bent the chassis from a previous accident.) and I need to re work the body. Ill have plenty of time to make the adjustments and have many months to get it working properly.

Also vega very nice setup uve got there.

[ajlovering12345]

The body is the same as the one I had at the event. Mencace GTR front with a Lola VDS back

The RRR is a Serpent Lolletta 1/10th shell. RC mushroom have them

Make sure you get some testing in before the event this time!

[fasterthanspeed]

Ill definately get trime to test this year.

[WackoWasko]

There should be a 17 and under class for kids with low incomes. haha, just kidding, its just I dont know how well I will do with my $300 budget (for hop ups). ajlovering12345, I didnt see a micro class in your post; are you guys going to scratch that class?

[fasterthanspeed]

Any updates on anyones rides? I dont really have anything to update on, as my workload for school is alot right now.

[ajlovering12345]

Wacko.

Is your car a micro? There are so many scales available now that its hard to tell whats a micro and what isnt. I dont want to have too many classes unless the entries get in the 100s! lol

All kits come under the same class. Scale IC or electric but even thats needs defining as you can get rail dragsters as kits.

I am in the process of ordring gears for the gearbox. When I get it working then i'll look at the car configuration to put it in.

[WackoWasko]

Ya, it is (at least, was) a micro RS4. It has a super sexy (but secret) chassis, and will fit a regular micro RS4 body, so I'm guessing it should be classified as a mini.

[crazyjr]

I had a phase ot two short in the 2250 in my Twinforce while on a speed run (intresting wreck, i'm glad i didn't have to ride it) and resulted in the esc taking some damage. I just got it back and thinking of a different setup, I may stick with a big neu in the twin, but i may go for something a bit more stable

[wqqdster]

Am working on a multi-engined nitro car, should be ready to test mid December. Was going to run tests using a stretched TC3 chassis but its too weak torsionally so have transferred all of the pick up points to a sheet of G10 fiberglass and will probably end up with CF for the final edition.

I found a nice smooth road in an industrial complex about 1,000 feet long and will use that for initial testing to see if this concept is even going to work!

A friend has offered the use of a small airport an hour north of me (rather than Sears Point) and he has a friend with a large vacuum table with which he can make Lexan bodies from my plugs.

Things are lookin' up!

I am sleeping on my design, I finally have a few dollars I can play with. It will be the custom fitting, maching and fabrication that I will need help with. Seems I don't own a CNC machine that can cut carbonfibler, mill derlin and nylon or mill out a custom aluminun wheel.

[wqqdster]

Hey Trailranger,

I don't have any of those tools either but its not the tools that make a superior car....its the ideas behind it and the ability of the builder. I have a 30 year old drill press that is my tool of choice. It has drilled and countersunk a jillion holes in a thousand pieces of aluminum, delrin, fiberglass, carbon fiber....you name it! I use it as a lathe, a surface grinder, tire truer, etc. With that you'll need a good set of measuring calipers.
Next is a dremel, (indespensible) then a jigsaw with a variety of blades. A luxury item would be a table top belt sander. With this set of tools you could build just about anything the high dollar guys can. Its just going to take you a little longer and cost you a whole lot less.

Don't know who said it originally...."Its a poor craftsman who blames his tools."

Kwicherbellyakin and get busy.

[Mod Man]

Yes much can be done without any machining tools. The issue seems to be accuracy, repeatability, and variety of materials and types of parts one can make.

I have had a number of projects written up in magazines (feature articals) that I used only a saber saw, drill press, and a hand file to make. It just takes alot longer and is tougher to achieve good accuracy.

Take your time, and go at it with a passion and you will be able to make more than you think. :)

The custom wheel would be the tough item to make without a lathe or 4 axis mill.

Three speed mock gearbox test.

http://www.youtube.com/watch?v=15NjAWqOnXs&eurl

You cant see the counter very well but the 2nd gear comes in around 3000 rpm then the 3rd comes in around 5700 and I rev it to 9600 rpm

The gears are too wide so I'll use 6mm instead of 8mm

Cheers

[ajlovering12345]

Here is a design to fit a serpent clutch to a one way bearing. If your going to use serpent style clutches for the 2nd gear you need the one way to allow it to dissengage when the 3rd gear kicks in

[trailranger]

You have a Drill Press!!! I'll bring the beers and the Carbon Fiber. I just own a Dremal and a Jig Saw (No it won't cut carbon :mad:)

My custom made parts list are shrinking as I find ways to reduce fabrication. I spent the last week deer hunting and didn't see any. So I had lots of time to think and making my car simple.

Parts I need to make.

Front "O-RING" wheels, milled solid nylon or derlin
Rear motor pod (similar to pan car motor pod)
Gear adaptors to mount onto 1/4" shaft and 3/16" shaft (Similar to the wheel hubs/axle clams on 1/4" axles but to mount standard 48P Kimbrough Spur gears on)

For the chassis I'll just have the Carbon Fiber pre-cut and I'll do all the milling to add the mounting holes and cutouts.
The body, well I'll just shape some balsa or foam and cover with micro-glass/kevlar/carbon for smooth, strong and skid resistant finish.

[fasterthanspeed]

well heres another thing off your list. I found the hubs for you.

http://servocity.com/html/set_screw_hubs.html

[trailranger]

I can hear my wheels a smoking soon!

For trial runs I may beable to get away with normal drag car "o-ring" wheels up front, but really I need custom wheels.

I have been shopping alot at harbor freight and I may pick up a mill/drill press and try my luck at making a motor pod.

I went ahead and orderd the hubs and Hitec Plug ends, I have been searching a long time for the crimp pins so I can trim down my servos on my race cars and make custom RX packs. I think all that excess wire is picking up RF and my spektrum doesn't like that.

[Mod Man]

CF can be cut with a jig saw or a Dremel. If you use a jig saw, you will ruin alot of blades (CF is very abrasive). But, you can use a Dremel with the abrasive cutoff wheels designed for cutting metal. CF actually cuts like butter that way. :)

Matt

[trailranger]

I've tried 36TPI to 12TPI jig blades and just about every blade breaks after 1 to 3 cm. Cut off wheels work so it may be worth it for me to get a right angle adaptor for my dremel.

Went out deer hunting this morning, so more time to think. Headed back early since chemo was tossing my stomach. I think I can eliminate major milling needed to make a motor pod and get a way just using a drill press and jewelers saw. I was thinking I would need to use the bearing off-set hub spacers like on pan car motor pods and realized that I already know my working tire diameter so no real need for adjustments like in carpet racing.

If I use normal o-ring tires I would need to cowl the wheels so that is easy too.

[ajlovering12345]

I must be using soft CF as my jigsaw cuts through it like butter

[trailranger]

I recieved the 3/16 and 1/4 hubs in the mail today. They were spot on and fit snugly onto the shafts. The Grub screw is of the hefty varity 8-32 x 1/4" which is perfect to making sure that it remains clamped in place. All my spur gears fit snugly onto the hubs so that is great!

[wqqdster]

Have run my four engined car a couple times now, learn a little something each time. The first time I learned that I can't run all of the engines on one tank so I installed two. On the second run I found I could run all four on two tanks as long as I only went 40 or so. As soon as I hit WOT a couple engines drop out but it was in the mid 60's. I'm now installing a tank for each engine (thought about doing that right at the start) and have to replace a gear. Should be ready to run again after the first of the year.

I also need to up the shift point, right now it seems to be at about 35mph.

Hi.

A company called CVTech-RD in Canada is sponsoring me by designing and building a CVT for my speed car. This will help in the low rev power problem that has plagued my IC cars. Here is a model of the CVT

[fasterthanspeed]

Looks really good. But whats up with those composite pipes? Go get some ths ones atleast! Overall looks really clean.
Me and u should go run together. i literally just finished putting it together into a roller.

[wqqdster]

" some ths ones"? Don't understand. I wanted to use Mac's pipes but they were too long and wouldn't fit under the body I have planned. The interior dimensions are very similar to most aluminum pipes and really that's what matters. The exhaust doesn't care what the material is.

Once the bugs are worked out and the body is made I'll replace the fiberglass with CF.

[fasterthanspeed]

The reason I say go with other ones just isnt because there composite, is because they are not tuned pipes. I remember changing a composite pipe to a tuned performance pipe, it created alot more power.
Good idea on using g10 for a prototype and then gonna go with cf later. Im doing the same thing with the upper deck for my car.

[wqqdster]

I've already got a ton of extra holes in the pan from moving the batteries and adding three more tanks up front. They're ugly right now but I'm just workin' out the bugs. Couldn't keep all engines running so went with two tanks, then all would run up to about 50 when one or two would cut out. Am optimistic that this will solve the problem. I'll replace them with bullet type tanks for a better profile.

Waiting on delivery of a gear and some warm weather for another test, hopefully New Years day. Never really got a chance to tune the engines last time. Also want to raise the shift point....have lightened the clutch shoes so its shifting at about 35 mph now, would prefer it at 50 or so.

What are you building? At least a description?

[fasterthanspeed]

Its a serpent Impulse. I am dropping a rossi maranello (same as every year lol) some capped tires, over gear it with different pulleys, gyro, and a serpent gtp body.
Ive decided to just take a built car this year, as everyone hitting those high speeds are doing the same and im going 4wd.

[wqqdster]

I agree that there is something to be said for existing engineering and that's why I'm using what amounts to a stretched NTC3. All of the drivetrain, with the exception of a fabricated drive shaft, is stock or mildly modified Associated parts. I have an Impulse and was looking at it if this design didn't work out but so far it has. My main concern was the one way bearings and the diff gears but they have all held up well. Although I'm not up the speed I'm hoping for yet, the initial acceleration is where these parts would fail.

I have put a gyro on it just as a safety factor even though a few people said it wasn't necessary with 4wd. Presently there is also a roll cage over those very expensive heads during testing.

My present gearing tops out at 120mph and will be thrilled if I get anywhere near that.

[fasterthanspeed]

Sounds good. What r the motors rpm rating?
What body are you going to use?

[wqqdster]

The engines are rated at 36K, Max hp @ 30K = 100mph. I have some sketches of what I want to build but can't seem to attach pdf files here. :confused::confused::confused:Its a fairly simple GTP style with more emphasis on down force than aero drag although I have a secondary tail designed that could attach to clean up the rear if all works well. If you want to PM your email to me I'll send it. A friend of a friend can vacu form the bodies out of ABS (he does a lot of airplane work) and MAYBE lexan.

Once the car is running well I'll start on the body.

"Wow, that body looks familiar!"

Not sure what you're alluding to, but there's only so many ways to draw/build a wedge body. Any similarity to something you've seen or done is purely coincidental.

That body is pretty much an exact duplicate of a body I made this summer.

It is cool that other people have some up with the same thing. :)

Matt

[wqqdster]

Hmmmm, I see what you mean. I hadn't seen your body before and they are very similar. I just went with fairly standard down force designs for the front and rear, enclosed wheels have been on every Bonneville streamliner since the 60's and I've run the side dams since the early 90's on my on-road cars until somebody complains. I felt that the engines presented a good sized hiccup in the down force air stream so the side dams would retain some of that pressure.

How did that one work?

[Mod Man]

It works fine. I had to take away some downforce from the nose. With the nose rounded, it is great.

I would not use air dams in the nose. You will have too much downforce. Also, you should run a gyro even in a 4wd car. I have been running gyros for years now (all in 4wd cars) and have had great success! Bear in mind, you will need a fast gyro and steering servo to make it work, though. I would say a GY401 with a 9254 servo would be the minimum.

Oh, lastly, where are you getting your CF from? I have 3mm CF in stock (18 inch by 24 inch panels). I may be able to supply you with CF cheaper than you can buy it.

I get those 3mm panels (3 square foot) for $150.

Matt

[wqqdster]

Thanks for the info. I suspected there would be too much downforce on the nose with the dams but its better to have it and not need it than need it and not have it. My nose can't be as sharp anyway now that I'm putting fuel tanks up there.

I had a GY401 gyro/servo setup installed before the car turned a wheel. Although I haven't needed it yet...well, see above. It does work pretty slick though.

The owner of my local hobby shop (Jake's perfomance Hobbies, Rohnert Park, CA) has been producing CF parts for his own design on road car and has offered to supply me with CF at his cost, but thanks for the offer.

My replacement gears showed up yesterday so hopefully I'll be ready to tune the engines in for a real test NY day.

[trailranger]

Batteries Bought! I went ahead and picked up 10 A123 26650 cells. I will make two battery packs with it. One 4S and the other 6S.

I have all the drive train parts

Just needing the charger and motor/ESC combo.

Making the motor pod will be hard, but I'll just take my time and do it right.

[balang_479]

that 4 engine monster machine looks interesting.. wonder how itll perform.

[wqqdster]

When you build something like that you have these fantacies of setting it down and running 90 right out of the box and then fine tuning gets it to 100 the first day......well, that didn't happen. I've had to take several steps backward and have been running it with one engine at a time to do tune up and break-in. With two engines It has seen 75 but the engines are just starting to come into their power in second gear and they overpowered the modified clutch shoes, kicking it back into first gear. I'm going to put the stock pieces back in and try them.

I have also had to experiment with gear lash ending up with none at all and when the engine starts powering up it moves away from the spur and gives it the proper clearance. I'll be installing delrin gears this week to help with that problem.

I've had a couple minor crashes but each time I run it I learn something new through the gremlins I have to fix.
