I have the kangke cap like yours with the TS .91 love how the plane flies. It has little wing rock during a harrier and walking the dog but it needs no correction. unfortunatly the motor hovers the plane at full throttle. I run a zinger 15x6 and it has plenty of power for walking around but you put it vertical and watch out! the plane torque rolls fast but ifeel comfortable with it to do it low even at around full throttle. it easily flies out with no altitude loss. I have some nice pics of it low and slow in a harrier but i gotta find um and a video of mine doing the IMAC basic perfectly. IT also does and INCREDIBLE lumchivak.
