Hello erverybody,

I´m thinking about a VTOL and want to make a combination of the Tricopter Y and a Vtol Tiltrotor. But there is no fitting sollution in the Airframe Reference…

For aerodynamic reasons the geometry of the setup must be spinned 180°. So the two “front” motors are in the back and are able to swap 90° horizontally while the single motor (with servo and normaly in the back) now sits in the front and can´t swap 90° horizontally.

Any idea if the setup can be established with the pixhawk?

Regards Dominik

Same question, Dom. Please keep me in the loop and I will do the same.

@dominik.b  
Is it what you need? (The sample setup is using Ardupilot firmware)

However, I found the the E-flite Convergence in the PX4 document. It is a Y3 airframe. I think the PX4 firmware can be applied to the VTOL Y3 Mini-Skyhunter too.
