I built the Gemini V-2 and I want to use it for VTOL. To do this, I am building a separate wing which will have a 4 motor configuration similar to the standard VTOL airframe. The only difference is that I need the two front motors to tilt forward when the plane transitions while the two back motors stay pointed up in there normal position. I need an airframe that will match this configuration, but I can’t find one in the airframe references. Does anyone know how I can accomplish this? I am still using the servos for the rudder, aileron and elevator.
