Okay, pokes aside, the rotors on the scorpion are probably too small to provide enough lift to keep the aircraft airborne.


rotor size alone can't decide lift, think of F-35 jet plane which has a very small fan for vtol use, that fan lifts nearly half the aircraft.

according to this article, the lift fan provides 89kn(nearly 9 tons) of lift.
