As an experiment I’m building a belly sitter with a single ducted fan mounted in front of the nose.
The VTOL duo tailsitter airframe doesn’t quite work for me as I need three outputs to control the motor:
Motor thrust.
Motor pitch.
Motor yaw.
Along with any aerodynamic controls.
Which means I need to add a new airframe, as per this:

Correct?
