well its a johnno 540 but thats the class i'm running so i can't change the motor, my o4-r went a lot faster, though it seems to be getting faster the more i use it, so i'll see how i go, anyone got tips on ratios though?

other than spped the car is wonderful, handles so much better

yeah..run smaller pinion. 34/90 is a bit TOOO much for a johnson 540. If you can get a hold of smaller pinion under 30, that'll be better.

I don't know what's the standard final gear on EVO III is. For comparison, I ran my TB01 with tamiya's stock setup (metric 48 pitch) 16/61 and the car have a lot of acceleration with a stock 540 especially with the Nimh batteries. Now, I don't know what's the conversion from the metric 48 pitch to the metric 64 pitch (can someone help me with that?). Since I figure (sorry don't have EVO III yet) 90T spur is the largest spur gear that Tamiya gave you for the kit, you might want to start by using 20 teeth pinion.

You also have to remember that EVO III is slightly heavier than TA04R so you want a gearing that has more acceleration (to pick up the weight) and lose a bit of top speed. Once EVO III goes, it goes, man! It just takes more than belt driven cars.

Hope that helps (and does not confuse you)

Default Chaange youyr gearing

Hawker,
you might want to go to a 38 or 39 tooth pinion to get the right speed out of that motor.

Default chassis twist ?car pulls to right or left....

Salutations Earthlings!
i do have a evo3 but i have noticed that the car pulls sharply to the side<i can't remember whether its left or right...>.is this a characteristic of a shaft driven car or is it because of the front one way? i have been told to use HARD springs to counter this but it only diminishes slightly...
the car is also very fond of skidding around when i try to turn. or brake.
HEEEELLLPPPP!!!!!

p.s.yes.......i know jack shit about car tuning......

KINGZJ,

Thank you for your recommandation, I appreciate it

Hawker,

Aside from getting the right gear ratio, you might also want to switch the rear suspension blocks to "AA" setup, instead of the kit recommanded "AC" setup. The kit setup's got 3 degree of rear toe-in, which is way too much for touring car racing. With the AA block setup, you'll have two degree of rear toe-in and with a 540 motor as your powerplant, you should still have plenty of rear traction and stability.

foampervert,

what kind of motor are you running? Torque steer is a part of the shaft drive car, but only when you are running hot modified motors. If you're running stock and your car is torque steering under hard acceleration, you car might be tweaked.

Aluma,

The best way I found to put a diff together is by using the following parts:

* TA04 complete ball diff kit (you'll use all the diff internal components in this package, except the outdrives and diff rings)
* TBEVOIII Outdrives
* F201 Diff Rings

Default hhhmmmmmm....

Well guys,

Its seems I cannot unload my car as easily as I thought, so I may keep it and see if I cannot free up the drivetrain enough to make it competitive. That and modify the rear of car to get rid of all the flex in it. I still think-even if I get the car fast in a straight line-its too flexible for high bite carpet and foam tires-but time will tell!!!

I have the same problem with my tc3 it pulls sometimes. I think it is due to the one-way. Now that I put the spool in it for foams it is pretty much a straight liner.
