Roll out ...
what is a good/recommended rollout for the Pro4. I race on a reasonably small but fast circuit ...
I'm after top straight line speed with moderate conering speed ..
Using stock 27turn motors with rubber tires...
cheers

I don't see a need for Steel outdrives. just too heavy and decreases acceleration. but TIR may release Ti outdrives to go with their Ti /Delrin Spools.

I noticed a lot of them using spool for the World Champ, just wanna to know the main different between 1way and spool in term of car handling....
Is it the main reason is able to apply hard braking to car?
What about cornering, is 1way has better cornering?
Is spool having the same front bevel gear break problem as 1way?

Ackerman
I would like to know what the different ackerman setting do.
The manual does not explain them at all and I have searched this thread and found contradicting answers. One post said that the #3 setting provides the quickest turn in and another post said that #3 provides the least turn in.
Does anyone know which one is correct?

I'm looking for some gear options for carpet for both stock and 19turn. I have asked at the track but got 2 very different answers. My track is only around 80' long by 40' wide. I had one guy tell me 27teeth for stock and another tell me 32t to 33t. I went with 30teeth and it felt pretty good but I was curious what others run. Stock motor is an Epic Binary and the 19t is a chameleon.

I just ran my Pro 4m last night for its first race and I noticed that the ball cups became very sloppy. I was wondering what some of you other guys were using. I race at RSJ's. I use to use rpm cups on my Losi car but I don't think they will work on the Pro 4 as the ball studs look way bigger than the losi ones.
I would like to know what the different ackerman setting do.
shorter ackerman = less aggressive, smoother
kevin k or someone could verify this...but in short i believe this is correct.

1 Least aggresive
3
2
4 Most aggresive

The main difference is that 1 and 3 have a lot of initial steering, but 1 has more steering at full throw. 2 and 4 will calm down turn in quite a bit, possibly even causing understeer. The 90 degree arm is just an extra part on the tree, so that that plastic mold is more versatile (as in if we decide to ever turn the servo 90 or something similar).

Need help with a cornering problem. I'm currently running Kevin K's carpet setup but I'm having a problem with the inside rear wheel lifting during cornering. It causes diffing and scrubs off a lot of cornering speed. I tried going softer in the rear but the problem stayed and the chassis just drug horribly. Can anyone suggest a couple of set up changes to try to eliminate this problem?

I've had good luck with 30 lbs. springs front and rear. Ran 35 lbs in the front a couple times, but usally 30, depends on how the steering feels. Rear droop about 3 mm over ride height.
take care
