Wanted to run this idea/question by the community, but perhaps it's already been covered elsewhere. Regardless.....
I've been running some designs on paper for a 3 motor VTOL design. Yes, I know it's nothing new but wanted to give it a shot anyway. My design will have two motors in the front and one in the rear, all in a pusher configuration. I plan on having all three motors pivot 90 degrees downward to act as a tricopter for vertical flight. I think I can work out the mechanics fairly easily but the electronics side of it has me scratching my head.
What I don't like about current models I've seen is that during forward flight the multi rotor flight controller seems to still be commanding individual motor rpm as roll, pitch and yaw inputs are introduced. Of course, during forward flight, all I want is control surface throw to achieve the desired movement about the three axis. I know that I can split each roll, pitch and yaw control to both the flight controller and the control surface servo but I want to 'shut off' the command to the flight controller during forward flight. I plan on using a high torque servo (1) to move the three motors through their 90 degrees of tilt travel via an aux channel on my transmitter. I was wondering if there are any electronics out there that I could connect to an additional channel in my receiver and, by programming a mix in the transmitter following the servo that is controlling motor tilt, have this aux channel shut off the signal to the flight controller while the motors are in the forward flight angle. Perhaps there is an easy answer to my problem but again, electronics are not my thing.
