And as you noticed the rear of the car on most setups{possibly the ones you have too} have the same rear arm/hub spacing.Not much more then a mm either way difference.I have run the hubs/arms Short front and rear and it actually did the opposite of what I thought.It made the car push mid corner from my findings.Hey George,when are you,Johnny,Joseph and Bob gonna start racing at Norcal again?You guys are gonna be so far behind by the time you start racing locally again,that you guys will never get on the same pace Josephs on!

Yeap! Since I tried not to take people out at the corner like someone you mention to get the pace on!

And you are right, when I moved the rear hub forward, feel little push. IMO

Well along with lengthening the wheel base you are changing the weight balance!! with more forward weight the rear takes less time to settle in which also makes for better reactivity!! i like to shorten the front and lengthen the rear so that way i create a better bias for the weight.

I'm certainly gonna try it if the pro's are running that way.I'm only running the s model and only have that adjustment for the rear of the car.

Default Middle One Way Pulley

Hi guys,

The car i bought came with central 18T pulley on one-way format.

I have good experience on nitro offroad but im pretty newbie in onroad electrics.

I tested the car at the track and it was nice feeling and the car is VERY agressive on turning specially off-throttle.

Now, what changes in performance i will find between same setup but using normal central 18t pulley v/s one way 18t pulley ?

BTW, this is for 13.5 brushless 6 cells nimh and rubber tires on outdoor asphalt racing.

thanks,

When you change the wheel base by the arm spacing, you will also have different weight transfer characteristic as well. When you shorten the wheel base by the front arm spacing, the car wants to transfer the weight to the front easier. (should create more initial steering) You will also need to make ackerman adjustment when you move front arms as it affect the ackerman.

For the wheel base change by the rear hubs, this will also affect the drive shafts sweep angle. When you move the rear hubs toward to the front, you will have more drive shaft sweep angle that will generate more forward bite. (I would say itís very similar to rear anti-squad characteristic) I think that shorten the wheel base for better rotation is good try, however sometimes you might have the car more pushing as the case may be.

I hope it helps a bit.

Try 1.5* or other less than 2.5* toe block as FF (the one up front), then it would smooth out the corner instead of the stock 2.5* make it too aggressive. What's the track you run at?

with rubber tires, the cyclone runs excellent on carpet.
For foam tires, you can convert your car to foam spec use with those parts below,

#61285 3.6mm Solid Main Chassis
#61286 2.5mm Solid Upper Deck
#61289 Solid Middle Deck
#61283 Chassis Post With ATC -Adjustable Torsion Control-
#72036 Aluminum Hex Hub Clamp Type (6mm/4pcs)
