Combining an Arduino with a flight controller to accomplish the VTOL transitional mixes worked well! Obviously it would be ideal to integrate the Arduino code into the flight controller, but that's beyond my current coding skill level. Also, the majority of flight controllers nowadays only have 2x motor outputs and 4x servo outputs, which would work for this aircraft, but would struggle with a more complex setup. E.g a quadcopter VTOL would need 4 motor outputs, leaving only 2 outputs for servos. 3D printer stl files: https://goo.gl/FZ2ep9 Arduino Code: https://goo.gl/fqLN9A OpenAeroVTOL: https://goo.gl/yCye1x Chinook Bicopter: https://goo.gl/jy5NwN 3D Printer filament sponsored by 3D Printz UK: https://3dprintz.co.uk/ Enjoy my videos?
