Hello, Im new here. Been doing alot of research and still looking for a possible tuning solution.

Ive been a Electric Traxxas Rustler for 3 years and Electric XTM XC that Ive had for 3 months.

I was on my 3rd tank of break in and the diff gear went out. I was only running it a 1/2 throttle, if even that much. I never got after it at all, just a smooth steady pace. I was running it on a tennis court so I didnt have to deal with any traffic. I was waiting till after this tank to adjust to the factory specifide diff adjustment setting. Snug, back off 1/8th turn. I called my LHS where I bought the truck 2 hours earlier said he would give me the new gear and thrust balls(had them order the aluminum diff, aluminum idler and carbide thrust balls) .

I get the new one installed and snugged it, though it was snug for 3-4 full turns. So I played with the adjustments till it would roll under its own power. It would move, but under any thing but gentle acceleration it would slip. I ran it for a few runs till the 3rd tank of break in fuel was used up. I let it cool down, turned the adjustment of the diff a 1/8th turn and it locked the rear into full posi. I figured it would losten up with some slow passes. Well it didnt, it stripped the spur gear instead. Now Im pissed. I ran to the closest hobby shop and bought a new spur gear and got that installed, lostened the diff up a tiny bit and it woudnt roll under its own power. I tore it apart again and the diff was smoked again.

All this and the motor isnt even broke in yet, not even 4 full tanks of fuel have been run. The shop where I bought it said to bring it in and he would send it to Duratrax to have them acess the problem. So now Im out $288 bucks, have to wait to get it back. Is there anyone who has any thoughts about what the problem is? I was torn between this Evader and a 2.5 Rustler. My buddy has 2 of them and never had any issues with either. He also has a Sport with a 2.5R conversion and a 2.5 Jato. I love Traxxas, but thought Id give something else a try. Now Im second guessing my decision.
