l post this in the wrong section, at the traxxas forum sry admins.
l'll try again !

l have an SCX10 axial rock crawler in the mail, would like to put a 2 speed gear box in it, convert it into a mud basher, it has a castle ESC and engine waiting to go in it, same as whats in a revo, l need to change the spur gear etc, but l would like to be able to change into a second higher gear, even if it means stopping to change gear with an extra servo connected, has anyone done this to an electric rock crawler ?
Anyone know of any gear boxes that might help in the conversion ?
