I finally ordered a BP-21 Outrunner for my slo-v. Still running 2c lipo tho, i'll need to get a 3c to enjoy the eye popping performance everyone is talking about. Today I got my stock 370 motor to altitude and cut the throttle and timed my deadstick endurance. It took 4 minutes to descend to landing with the prop motionless. I was wondering how much extra a folding prop would have given me. Anyone where to buy 8x4 direct drive folding props?
