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

Left-wing aileron
The maximum and minimum deflections of the control surfaces are in degrees.

The area of the control surfaces is considered a rectangle.

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.

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.
