It´s neccesary an airspeed for cuadplanes, or it´s possible to fly without it? I never use them.
I found this which sort of indicates you can use it without an air sensor but probably better with one. http://discuss.ardupilot.org/t/quadplane-without-airspeed-sensor-problem/10975
Thank´s, I read something that analog airspeed doesn´t have good accurate, it´s enought for a cuadplane or I need a digital one? Wiki doesn´t reccomends for newbies, I´m an eternal newbie.
