I have a Clodbuster that I use to race around and some minor bashing with. Ive upgraded it to Traxxas 550 Motors along with a Traxxas ESC, dual 5000Mah Nimh batteris. Rear steering lockout and a diff locker, and moved the steering servo to a front vertical axle mount.

When I bought the clod the guy had a Traxxas 2075 servo on it mounted in the stock location. I swapped it out with a metal gear Hitec HS-5685MH 90degree servo and this is where I ran into problems.

First the turning radius is ridiculously large.....Im figuring mainly due to the servo being a 90degree servo and I eliminated the rear steer. Second issue I ran into is I managed to strip one of the drive gears. I opened up the servo and found that the gear i stripped is an extremely thin gear, not what I expected from a "high torque" servo.

So Im kind of looking to change things up. To replace the stripped gear, and to get a programmer to change the rotation from 90 to 180 would cost me the same as buying a new servo.

So my question would be, what would be a good 180degree servo that has solid gears that wont strip that I could use for this application? Or should I be looking in a different direction?


Any help would be appreciated

Those trucks have 4ws for a reason. You will never get the same turning radius with just front steering and a diff locker in the rear. That alone creates push when turning. 90* of servo rotation is fine, just get a longer servo horn to increase steering provided that all the steering linkage and axle joints don't bind at a higher turn rate. Recheck where you have your steering end points set at. Looking at the specs, I would buy this servo again. Servo City has it for $39.99...that's a great deal.

Another thing is how many volts do have going to that servo? That is a HV servo.

I know the turning radius wont be the same, I dont want it the same. Stock 4ws With 2 550 Traxxas Motors and 14.4V powering those motors, when turning the clod had high tendency to flip. Im not looking for crazy performance out of this thing, I know the design of it is 20+ yrs old and its not really designed for what I do to it. But right now it has roughly 7' turning radius which is huge

The plan was to get a servo mounted on the front axle, then shave down the stops on the steering blocks to get a tighter turn radius. I just never got around to shaving down the blocks, with that said, with the servo mount kit I bought and the servo i have, shaving the steering blocks at this point wont change anything, not unless i get a servo with a larger degree rotation. I do have a decent sized servo horn already on it.

How long is the servo horn you have on there now? I was thinking about what you said about getting a servo with 180* of rotation, but i'm not sure how much torque you would lose compared to using a longer servo horn.
