How to yaw in "Standard VTOL without rudder" configuration? #13997

Open 109nik opened 4 years ago

109nik commented 4 years ago

Describe the bug I am making a new air frame in 'VTOL configuration without rudder' and I desire to achieve yaw with ailerons and elevator only and not using rudder . Air frame has two ailerons, elevator and pusher in fixed wing mode and 4 motors in multi copter mode. I need help in mixing actuators in VTOL configuration without rudder. I can see Plane A-tail and Plane V-tail without rudders.

4 motors dont work in fixedwing modes . they are for takeoff and landing .

@109nik did I understand you correctly, you want to use the multicopter motors to control yawing in fixed-wing flight? This would need much more changes than only in the mixer. Like @moreba1 pointed out, the multicopter motors are only active in hover mode, and not in fixed-wing mode.

sfuhrer commented 4 years ago

@109nik while certainly improving flight performance, active yaw control is not crucially required for most fixed-wing vehicles. If your system doesn't fly nice without a rudder I would recommend to either add one or change the aerodynamic properties in a way that it becomes passively stable in yaw (the easiest thing there is to add/increase the size of the vertical stabilizer).
