I received this morning a brand new CEN Hi-Torque servo, I thought great! My steering would be much faster now! But I hit a few problems The plug that fits into the receiver didn't fit (too wide) so I had to trim that so it would fit.

Then I put the servo arm onto the servo & tried left & right turning..But whats this I hear [&:] When I *try* to turn, it interacts with the throttle servo & the throttle servo starts to twitch and both servos make a mmming sound.....
So I *try* to turn left on my controller, and the servo turns left sharp and quick. But huh?! It stays in the left posistion......And when I turn right, it brings the servo arm back into the centre and about 1/4" to the right...This is my 4th...yes thats right , FOURTH, servo I have put through my ATX. Something isn't right...... I risked reving the car on a couple of bricks, and when I have the car got some high revs, the servo would stop in that position for a second or two then It would lower the revs (Controller already lowered).CEN Racing, any help please? This is brand new and shouldn't be doing this.
