can anyone help a newbie/beginner. am trying to fly the new Alia 250 in xplane 12, using Ardupilot so I can fly Autonomously without a joystick, just want to learn how to fly a complete mission start to finish with no input from me. am able to set up and arm/take off automatically in auto mode, but straight away the quad rears back and crashes. Andrew Tridgell`s video on utube shows it is quite simple but he saeems to use a json dref for the Alii quadplane, which i cant seem to find and wouldnt know how to implement. is it necessary to have to use a dref ?. please help.
