Folks. I’m setting up a new 5t v2. I took off the steering servo horn and let it center with the radio. No limits set or sub-trim set. With the low number of teeth, 15 I believe, I could only get the horn back on close to center favoring toward the rear of the car in direction.

I then adjusted the turnbuckle on the link from the horn up to the steering to get the wheels straight. Did a low speed break in drive to start breaking in the motor.

I noticed I have a huge amount of wheel turn to the left and only half that to the right.

I ended up setting the left travel limits to 50% to get both sides even. Am I missing something there? I just don’t see how to get close to max steering on both sides.

I’ll try again, but I think when I tried the last time one tooth movement put the horn in the same problem except it was now pointing towards the front of the car and I had a hard stop limit when the servo arm hit the servo
 
Sorry, I was thinking push pull set up. The method works because most arms have an of numbered number of splines. Do you have another servo arm to trial fit?

Have you reset the center electronically yet? Depends on radio for procedure.

Yes, that would not have worked at all. I placed the arm in the next tooth clockwise moving it forward. Then zeroed out all my travel. Cranked the pushrod turnbuckle almost all the way together and got very close to straight wheels again with better L/R travel. Just need a nice day to try it out. Fingers crossed

Do you mean turn it so it points toward the outside of the body and not the inside?

I would actually try that as well. I know I had that issue with a Losi (once before). It seems counterintuitive, but linkage may work correctly that way.

Best is take servo out of equation, just pull horn off. Line up wheels manual, connect servo to electronics (but not horn/hub) make sure radio is zeroed out.
Then connect horn, to closest tooth (it may be up to 5% off trim. But not 50%

EDIT: Meaning turn servo 180 (not linkage). See if it lines up better, after manual centering wheels (linkage)
 
Well I gave up trying to center the steering linkage on the servo. 15 teeth just did not work, always too far from 90 degrees. So with no experience I took the steering servo out and dismantled it. I reassembled it moving the gears over and over again until just by luck I got it together with the teeth in the correct position to have the horn at 90 degrees. Now everything can be adjusted. Geez, what a nightmare.
