Gress Aeronautics is an R&D company specializing in VTOL air vehicle utility.

" ... for the UAV market, [Gress] bicopters have big advantages over other platforms such as the quadcopters." - Model Helicopter World

.



We use propeller gyroscopics not only to enable pitch control but to enhance roll control as well - please see our Bi's in Space video at left.

They take control beyond what's possible with thrust changes alone (what quadcopters use) and pre-empt the effects of wind gusts.

Bicopters can be completely streamlined and - since only their propellers tilt - remain completely level in forward flight.

This allows simpler, tighter camera installations - without view-obstructions like extra propellers - which of course helps the aircraft stay streamlined.
