Maximum speed: unknown. Maximum altitude: unknown. This aircraft has the same airframe as the normal Thundershrike (also has reinforced wings to survive "the hummingbird effect" for longer periods) but has modified engines capable of pushing the aircraft to just under 25 times the speed of sound (18,500 mph record max speed of previous upload). If the wings start to beat rapidly (like the wings of a "hummingbird") pitch rapidly in any direction to slow down below 4000 mph then climb to a higher altitude. This arcraft also contains vast fuel reserves needed to feed the two EXTREMELY fuel thirsty engines for an unknown amount of time (fuel will always be at 100%).
