What is the largest challenge to control this plane in hover mode?
The Verticopter was not designed to be a perfect hovering machine, and is not intended to replace the helicopter. Instead, the Verticopter excels at short take-off and landing maneuvers and “jump take-offs”. Tight hovering maneuvers require a fine control of the weight distribution and may also call for the use of compressed air puffers if the wind conditions are weak.
