It is easy to pull of the gear box out and put it back together. I just did it for the first time last month. Just buy any k 11 box and just replace the broken one. I have no idear to rebuild gear boxes so just bought a replacement and replaced it.
Ok thanks for the advice. I just bought a super s just because all you guys said they were cool. I also have a slx. I just can't get enough of them, just needs a little more power.
