Last updated 7 months ago

The Firebird has four control surfaces, with roll controlled by the 2 ailerons, and pitch and yaw controlled by the v-tail ruddervators.

Deflection Information

The maximum and minimum deflections of the control surfaces are in degrees.

Aileron

V-tail

The maximum value is measured when the external edge of the control surface is pointing up, and the minimum deflection when pointing down.

Area

The area of the control surfaces is considered a rectangle.

Required Torque

The required torque to actuate a surface is the torque required to maintain the servo in maximum deflection + the friction losses. This data is documented here.

Servo Information

The servo model is the same for all control surfaces of the aircraft. It must have a >4 torque safety coefficient to the maximum required torque to actuate the surface.
