Mjd for that Habu motor its a bit high on the KV for anything over 4 cell on that plane. I have flown many of these motors and the best all around prop was a APC "GLOW" 6x4. not the electric 6x4 but the glow 6x4. If I remember correctly it spun that prop around 34,000-35,000 on the ground. I think it was good for 4 pounds of thrust also. With that prop hand launch will be no problem and speed will be around 140. although that is a wing the fus is pretty thick. if the air frame will hold up run a Neu 1517 1.5Y on a 7.4x7.8 Carbon at around 32,000 on 6S pack and around 140 amps. This would put it over 200 pretty easily.
