tim,
thanks again for all the info. i was looking into getting the guapner 3-bladed 12x6 but if you find that the 12 1/2x7 or the 12x8 work better that saves me money. thanks for all the tips. very helpfull in what to be ready for with this plane.

justin,
a 20cc engine is the same as a .91 four stroke. this plane only calls for a .70. that engine will be way to big!!!!!

tim...thanks again. keeps us posted!!!

thanks
dan
