Yea....I wish I could find metal gears, maybe going to have to look at the Robinson aluminum gearboxes, don't knmow if the gears are nylon or not. I am going to see if I can send the engine in for warranty repair, I put an OS CV-X .12 back in it, ( had one I didn't use in an RC-10GT), doesn't seem to have as much low end punch, but I wouldn't expect it to being a .12, I want to try the OS .15 CV-R, at 1.1 HP, it should have enough power....if I can get the trans problem fixed first.....Coop
