Hello, I have posted elsewhere on this, but I have to say, this axle thing really bites. It seems to be a real sore spot with my Nemesis. I could understand if it were jumping, flipping, rolling, or hitting something, but to snap the dang thing on take off is a little much. I ran only 3 tanks to only have this happen once more. THREE TANKS, c'mon now, it was run on in a flat soccer field and a open parking lot (no curbs) and then on tank three I start it and take off then there goes my wheel, HELP, runaway wheel!!! Man it seems that CEN would have a better design for this and not made it hollow. Good idea and all for the set screw, but just bad execution, solid would probably been better here, I don't know.? I just can't see shelling out the $$ for this thing any more. Good luck future owners, unless something is done.
