Pegasus, that is some great work. I looks like your on your
on your way.

I have some advise. In order to get something to hover
the reaction control system (puffers, tail rotors ect) must
be able to produce 8-10 percent thrust, of the weight of
the plane. So your 30 lb harrier much have ~ 3lbs of thrust
in all axis, except yaw. This thrust much have a very
quick reaction time also.

Before I built the Rig, I tested a bleed air system
using shop air at 40 psi, and was unable to make more
than a few oz of thrust. There was just not enough pressure.

Good luck with your project.
