I would recommend a stock setup too, it keeps it light and it flys great IMHO.
Everyones stock main and tail motor will burn out sooner rather than later, get a GWS B2 tail replacement from www.aircraft-world.com
then fix the main motor.
Unfortunately the brushes in the main, and replacement main are useless they are way too small. And any better quality replacement requires playing around with pinion sizes etc. (which can be hard to do in Australia). So when mine burnt out I just replaced the brushes, it is do-able it just takes some fiddling about, this way you keep the same windings and you won't have tail problems. I've been meaning to start a thread on brush replacement, so keep an eye out I'll try to get something on the ezone by the end of the week, if you have any Q's PM me.
