Stripped Spur gear after jump

[G35driver]

I am a begininer, i stripped 2 spur gear after a few jumps yesterday. Did i make it too tight or loose? There is no movement from the engine mount! Can you please help? Thanks

sounds like it is too tight ,
and if your on the throttle when you land all the power goes to the weakest link,,,the spur ,
and btw: what are you running ??

Actually I'd suspect it's too loose. When you set it, there should just be a tick of play. The best way to set mesh is to put a piece of standard printer paper between the gears and then push them together and then tighten the engine. Roll the gears so the paper comes out and you should have good mesh. Sometimes if you set it too loose, the chassis will flex a little when you land hard and will pull them further apart causing the spur to strip.

i was referring to the slipper itself ,
and your right candy man that could ver well be the problem also ,but a hard onthrotle landing will waste a spur also ,right?
