The Lightning is capable of speeds up to 414 mph and an excellent rate of climb, powered by its powerful twin Allison V-1710 Engines. The Allison engines drive a 3-bladed Curtiss Electric Constant-speed propeller, counter-rotating to eliminate yaw tendencies, generating up to 1600 HP in each engine at a 2:1 gear reduction ratio. Dogfight performance is improved drastically with the addition of innovative technology for its time, such as the hydraulically powered Aileron Boosters, Manoeuvre flaps and Dive Flaps.
