[Help] How do you know a pullback motor is broken?

[Didumos69]

I have a single copy of the latest version pullback motor. I'm using it for my TC13 entry, but since today it seems to behave differently. When I wind-up the motor it sometimes gives a lot of friction and it seems to give less power when it unwinds. I did over-wind-up a few times (it clicks unhappily when this happens) and I'm curious whether this could have do everything harm.

So my question is, is this common behavior for a broken pullback motor, or not?

My somewhat broken pullback motor has a similar issue, except it sometimes does not wind up when pulled backwards. Maybe something inside is broken or rubbing? They are easy to take apart.

Okay thanks. I will probably buy a small set with a new one. I borrowed this one from my son and he is not going to like the issues it's having now.

The clicking when over-winding does not break the motor, it just tells you that you've wound it up far enough.

I'm not really sure what is wrong with your motor, but it's not from pulling it back too far.
