I've removed the big yellow cap that you get on new stock motors.

Will my motor still be okay to run??

Cheers!

I don't think it's a cap. Someone posted that it's some sort of fuse. I think it will still be able to run normally. I think it's supposed to trip before your FETs get fried.

Yes T, Spoon is right on. It's a circuit breaker that trips out to stop further damage to the car. It resets after cooling itself. Removing it is not a problem.

See link - http://en.wikipedia.org/wiki/Polyswitch for a decent explanation on what a resettable fuse is and does.

Now that's one hell of an explanation and just how I was going to explain but thought I'd not baffle you with science :D :p

these seem like a good thing if your running the minimum fet stack for a certain mod motor. That wiki link gave a nice place to buy some in different ratings

Oooo, well if it's protecting my FET's then I might re-install it. I thought it was souly to stop over heating. :o

i remember posting the kyosho warning somewhere... they mentioned it to be a circuit breaker... which shuts down the board so that the fets don't blow... it offers some solutions to avoid this from happening... i.e. wait 5-10 min for it to cool down, switch to a lower toothed pinion, etc... hope this helps... :D
