garzzar:I have never had problems with the engine mounts...[:-]Who did???The rest of the problems are all newbie problems.Tighten the servo saver nut and locktite it even before your first run.
Brakes?Only a matter of knowing how to tighten them up with no brake drag.(Fresh charge in the batteries will help.)
Pull start??If you go wild on it,it might give trouble....
PS answer:Yes the tires are pre-glued.There is a sticker on the reciever box lid with the frequency number on it.
brainerj:Tightening the SPUR GEAR might help a bit,but you want it to slip a little when you are jumping with it.
Stiffer springs on the clutch shoes will also allow more wheelies,since the clutch will not engage until the rpms reach a certain point.
Pauole:Tuning is a big part on how much power and speed you will get out of the engine.Always keep a good smoke trail coming out of the exhaust...
