So just completed my 2 tank tick over run in few weeks ago so went out today for the 1/4 throttle 2 tanks that was successfully done moved up to the 1/2 throttle run in done a few little I mean little jumps and lost all drive stripped the centre gearbox down and not being familiar with gearbox’s I think the gear wheel on the reverse module has sheared. I don’t really know why box I have it was a eBay buy but I would love to get rid of the reverse. Can’t be up to much if it’s breaking at 1/2 power. Any ideas how to do this I’m clueless with gearbox’s
