Is anybody using the Jet aluminum c-hubs on the front of their car?? I can't figure out how to mount them. They don't have the same 3 hole adjustment like the stock ones.....I also bought different shock towers, but I don't have hardware to mount them. I need spacers and machine screws. Can anybody tell me where I can get them from??? Thanks....

on the aluminum c hubs, to mount the upper link you will need a machine screw for each one. it will just thread in vertically to the top of the c hub. you can adjust the roll center by inserting spacer between the hub and the upper link.

Default C-hub

M using a Jet Chub 3 degrees!!

Just like what spaz456 said

you have to use a machine screw
you will also need spacers between the c hub n the ball cap

and you might have to reposition the turnbuckle on hwre it connects to the shock tower.

Thats all!!

Default Question

I have just noticed (recently) that the steering of the Pro3 is a lot slower than the TAO4, TC3 and Yoke?

I have checked my car and the steering system for binding and there was none. Cleaned it also and when i remove the linkage to the servo, it does move freely and bindlessly (s.p.?)

I am using a Bnew Futaba 9402. From a KO PS-2173 cz i thought it was broken. but sill the same.

The guys at the track said the reaction time of the steering is slow?

Why is this?

Is it because the steering system has a lot of linkages??


Thanks for the help!!!!!

The Futaba 9402 is high speed servo w/ 0.10sec. transit time
this is great servo for the car. my servo has the same speed. and have no problems with reaction time. Linkage should not be a problem.. other cars have the same amount. as long as nothing is binding than you're ok... maybe it's the radio/receiver. What are you using... I'm using the Futaba 3PJS w/pcm receiver on my Pro3.

Default Thanks!!!!

That was a quick reply!
M using an LRP PHASER 40mhz and a KO EX-11 TX.


Actually its okay for me or I am used to driving that way,its just that I could not make aggresive turns.

And I noticed this when I used my spare car (tao4-R)
it turns a lot faster.

Is the 3 degree c hub a contributory factor??

Yes...get the 3deg C-hub and front one-way.. you'll definately corner alot faster and increase steering dramatically. if you do get the 3deg...use black sway bars in front.

Just a guess, do you have any settings on your controller that might be slowing down the servo any?????

I am a little confused , does your wheels turn slow like it is binding even on the bench or does that car turn slow (push) while driving?

Default pro3 steering

lem2: if you compare the turn-in while the car is running, most probably it is on the set-up. if you want to find out the steering response of the servo itself, do it while the car is not moving. if it is slow, loosen the purple nut on the right bellcrank and/or replace the bearings in the bellcrank. you'll be able to determine if there is binding in the steering if you remove the servo linkage.

i use a 9550 servo (it is a bit slower and a tad lower on torque) and a 4deg c-hub but my car turns-in very aggressive. if you know jake de dios, ask him how aggressive my car is...he drove it once
