Brushless Rustler rear-end
I have a XL-5 that's been upgraded to metal gears in the rearend. Ringed Diff... Idler... clutch shaft... etc. I thru a MM 5700 setup in it and took off. Everything worked great for a while...
I heard a noise, that sounded something like a gear letting loose when under a load. I thought maybe the spur gear was loose... and causing it to work fine until loaded. Not the case. I figured I might've broke a tooth off an internal gear... and broke in to the rear to figure it out. There's nothing noticably wrong with the gears or diff internals.
Under low throttle, 10-20%, I can putt around without a problem. When I hammer on it, it sounds like a gear is backed out and it slips really bad. I can manually hold the rear wheels & turn the spur gear by hand and recreate the noise.
Resistance... resistance... *POP*... resistance... resistance... *POP*
It definitely sounds internal.
What do you think it could be? All the bearings look good & have no play... the housing is in good shape...
I'm at a loss. I was wondering if the Rustlers were known for having something wear to cause this issue.
