Today i think my Motor is went down.
The pionion gear is bucking if I push the throttle. So I think there is nothing more what I can do, or?

Which motor alternatives are there?
Which Mamba fits best for the mini Revo? What are things i`ve to look for?

Whats about the gear "protection" if i use the mamba? What kind of "spacer" is it on the pic to mount the motor? Do i have to run my lipos in parallel?

thank you in advance!
