About


The XH-525 Hellbender was designed as an experimental helicopter for use by the US Air Force to replace the aging A-10s currently in service. The reasoning behind proposing a helicopter instead of a jet aircraft was recent advances in helicopter technology. The Hellbender can take off vertically like any traditional helicopter, but has a rear facing prop that provides the Hellbender the ability to cruise at speeds up to approximately 230 mph. Without needing a runway to operate from the Hellbender can be used in more remote locations. The Hellbender was designed with a fighter cockpit as to make training aircraft pilots easier.

Use trim to achieve stable hover if the helicopter drifts forward or back.
Hover is between 32% and 33%. Any advice is always welcome.
