The wingspan was stretched an additional ten feet (three meters), the fuselage was lengthened, the tail surfaces were enlarged, and stabilizing fins were added on top of the upper wing. The N-9 was initially powered by a 100 hp (75 kW)

for this achievement. More important, however, were the stall and spin recovery techniques he discovered while flying the N-9 that day. During his first three loop attempts, the N-9 stalled before he reached the apex of the loop and fell into a spin. He found that by releasing back-pressure on the

stick and aggressively applying opposite rudder to the direction of the spin he could change the spin into a normal dive and recover, something previously thought impossible in an N-9. His stall and spin recovery techniques remain in use to this day by aviators around the world.
