Two hurdles to overcome..... VTOL and Transitioning type craft. I have selected this model for an experiment as I believe it may act as a wing. The plan is to maiden it as shown on a 4S then stick some 8" props on for a 3S flight so I can check how stable it is and how much power it can handle. After the maidens are over I will put the PX4 in it and set it up as a flying wing. The rear rudder servos will become obsolete.......Too windy to test it today so we will have to wait till next weekend...... heres hoping...
