Thanks for the responses guys. I'm on page 18 of the thread roltech got me started on. Seems to be some useful information regarding the 51 pts. I checked out the servo's on my plane, having read something about them breaking off from perhaps some inadiquate CA attachment. The servos on my plane are screwed on. Looks like some guys are modifying this thing right out of the box to be something it was never designed to be and having motor issues among other things. Why not just go purchase a plane designed for more hard core flying instead of all the mods. I know how it can be with modding things. I take brand spanking new $8,000 snowmobiles and have a pile of parts taken off them, on the shop floor, swapping with hp parts. I aslo just dropped $2,000 rebuilding the relatively low mile motor, connecting rod sticking through the block. hmmmmmmmmmmmm............. It seems power mods in all sports lead to engine trouble.
