I am going to try a rimfire 36-30 1450 with a 12x3.8 apc slow flyer prop running on a thunder power 2s 2070 pack
I am waiting for the battery
pointing up the nose with a 4200nmh 6 cell pack from one of my cars hanging and it was still pulling my hand up
think I have around 2 lbs of thrust "just a guess"
all up weight should be 17.5 oz
cant wait to hit the air with it should realy honk
