INTERESTING, VERY INTERESTING!!!

oops, you're right, 4.6 or so is about right for that 270' straight.

I'm getting severe 'coning' of the rear tires on my R40 (looks like too much neg camber), the inside portion of the tire is wearing much faster than the outside. Using all stock settings (6mm gap on the rear camber links), with 40/40 nitro shoes.

I read somewhere that this might mean that I have too much neg. camber ? Car handles ok, if anything a little bit too much push, but overall not too bad. Should I reduce the amount of rear neg. camber?

Coning is from too much toe in and or too much camber. The stock settings are fairly extreme when it comes to both, but makes the car very stable and easy to drive. You should be able to back the toe off to -2 degree per side, and the camber to -2 degrees per side as well with decent results. This will also help you car turn in better, but you may need to be easier on the throttle through and out of the turn.

If your gearing for a track and you have plenty of motor do you go with the tallest gear still wich is beter a 4.95 or 5.30. does any one go by the ratio or does it to confusing

nitro13

4.95 for big track

5.30 for small tracks

nitro13,

I would use a 5.3 to try to take advantage of the high rev on the motor. If I had a motor which has more bottom / mid end characteristic, I would use a 4.95. But again that would depend on your track.

To further add to the confusion, the gearing to complement the motor much depends also on the tire diameter your're using to determine the tire rollout.

I'm curious.. and am thinking about trying out a one-way with a 4 gear rear diff.. has anyone had any good results? I'd like to get a bit better steering on off-power turn in.. right now the car runs a bit wide. comments?

(although I haven't driven a car with a one-way before, i'm familiar with the braking issues and need to change your driving style)

If the only thing you are looking for is a little more off-power turn than a 1-way may not be your solution. In general a front 1-way will give you more steering both in and out of the turns at the expense of decreased braking ability and stability. When you hear that you have to adjuat your driving style use one what they are actualy telling you is that you have to be more fluid and smoother with throttle and steering imput.

If all you are just looking to add a bit of off-power turn in I would suggest you first try to decrease your rear droop and / or front caster.

By running less droop in the rear of the car you will allow more weight to shift to the front of the resulting in an increase in off-power steering primarily around the middle 1/3 of your turn.

A decrease in your front caster in simple terms will make your car more responsive entering turns both on and off power at the expense of decrease steering on exit.

You may also want to try a lighter front spring or softening the front roll bar. In general both of thease changes can increase both on and of power steering by allowing the car shift its weight more quickly. When trying the above I would suggest starting with the sway bar.

For anyone running the 4-gear diff: what have differances have you notived between this diff and the standard 2 gear. I would expect that it has a similar result to running heavier diff oil, if this the only differance or am I missing something.

Thanks for the insight. Call me dumb.. but is the stock setting for the front sway bar at it's softest setting? (both blades horizontal) I'm not too familiar with the front blade type sway bar.

Yes, that is the softest setting as you stand the blades up the tension will increase.

Hi guys,

I am use to 5 cell hump pack with older car. But I know that the R40 use a flat pack right?

So what kind do you recommand, voltage, amps, brands...

I don't really know which one I can pick up. I have a Futaba Receiver...

Thanks!

I have the Trinity 1150 around 30 to 40 $ for it any flatpack 5 cell should work
