I have the GWS stick fd and anything stronger than stock would tear the wings off this puppy... but I'd like to (as soon as I finish destroying this one ) move up to the zero or the new mustang (ie I do like the GWS kits) but I want to move up in speed too, not float around like the stick does, a power dive already broke the wings once so, I read this thread with interest,, do keep us posted whichever way you go,, but the brushless motors and controllers do seem rather high dollar.......Rog
