So heres my TRX 2075...

[sliceofnoob]

So i went out today for some crawlin, took quite a decent tumble down a hill and went to steer right and had nothin. I would turn right and the motor just spins and when i let go it keeps spinning the other way to get back to center, but that wont happen because i stripped the gears yay!! I ripped it apart and low and behold the middle gear and output gear were stripped, looks like two teeth on each gear. Ive heard ppl swapping in metal gears for these things but cant find a solid answer, could anybody that has done this before tell me how they got their swap done?
Heres a pic of the servo apart:

I dont know anything about it but I cam across this on google:
[RC] TRX 2075 metal gear swap 1 - YouTube
Looks like the gears are brass, probably wouldnt last all that long in a crawler anyways.

I would just cut you losses and get a real metal gear servo...
