What control surfaces do I need to move to do a roll in a model aircraft? Figured that this was the better site to ask than drone SE, but if I'm wrong just let me know.
I'm making a spitfire model and was just wondering how do I do a roll? I have elevator, rudder, and two connected ailerons.
What control surfaces do I move to do a roll?
The ailerons should be connected so that they move opposite each other. When one aileron moves up, the other one must move down, and vice versa. In fact, in full-size aircraft, the ailerons are connected so that it's actually impossible to move them in the same direction*. So, to answer your question, to roll to the right, the right aileron must move up and the left must move down.
*Well, certain airplanes have &quot;drooping ailerons&quot;: when the flaps are deployed, it causes both ailerons to tilt downward slightly. But this is about increasing lift at low airspeeds, it doesn't affect how the ailerons control.
