Servo arm rubs against the fron gear case. (RC18T)

clamber · 12-31-2008, 06:22 PM

Well I just put together an FT 18t, only to find that the steering wont function properly because the servo arm is rubbing against the corner of the gear case.

Why is it doing this?

Can I use some sandpaper to eat away at the part that its rubbing against?

Will upload pics momentarily!

The red is where it rubs when the servo turns:

Trim the back of the ballcup with an exacto knife.
A mamba system will not destroy the diffs!!
Landing jumps with the throttle pegged, or slamming it from reverse to forward will.

I agree...I been racing my rc18r for a whole season and now we and no problems out of the diffs, but im not using reverse.

look at your cars servo.in picture. the servo holder is not in the right spot. top pin not on front part of servo. when it in your steering links would pull back from diff .

Can you elaborate on this for me, Im really confused!

This was my first kit and the first time Ive ever done anything with a servo.

edit: Nevermind, I think I may understand!

+1, good catch

that servo is definately in there crooked and not all the way back into the mount. looks like you were in a little too much of a hurry putting things in the car. be paitent and take your time.
