Spinning Pinion????
 

My front Pinion keeps spinning. Not sure way. I have tried different pinions. Still spins off. I'm running the 2 piece Design from RC4WD. Is this a common thing with there Pinions? Also the output shaft on the Axiom motor isn't much of a Flat spot. So either the shafts wasn't made wrong or my Pinions are just retarded. If I can't figure this out. I;m just going to get the new V10 Axioms....Any thoughts would be nice. It's getting old.

I was thinking of getting the one piece pinions....They just make more sense to me anyway. I'll try that, Thanks Dez as always....

They stopped making the 2 peices because of this issue. I believe they told everyone to use thread loc on the set screw.

I've used thread lock. I just all these off them a couple of weeks ago. I;m going to send them an E-mail.

Set screws
 

Lock tite the screws works.But if you can find allen tipe set screws they will hold better because you can turn them a little tighter.Dont forget to use the Loc-tite medium stregth."thumbsup"

RC Guy 8t pinions are awesome... Never had ANY issues with them... They go on easy, STAY on and on't come loose... Ever... I run stock Mabuchi's with them on a Gecko II kit...
