[teamorsum96]

hi,
i just want some advice on my motor,
its a tekin mini rage combo brushless 1/18th motor , but can you tell me, is it rebuild able?
because half way thur the meeting, i had a big crash ( ok i was messing about doing big jumps off the stage) lol and found that the end bell of the motor had popped off, i pushed it back in and it ran fine and won my final.

cheers jamie
