I already have a fixed wing rc plane, but if I want to modify it to a quadplane (VTOL), how should I do and what others device I have to buy? I am really a noob in RC plane, need help!!
look here: http://ardupilot.org/plane/docs/quadplane
there are a few build logs linked aa well.
Thank you, but the web seems not valid.
