Setting Servo/PWM output, proportional to ground speed


I would like to adjust the position of one of my servos in proportion to the ground speed - as the plane speeds up, the position angle of the servo automatically alters in proportion.

The only feature I see close to this is automatic flaps, but even in that case flaps only adjust to 2 unique positions based on speed thresholds.

Does anyone know of a feature or trick without having to go into firmware programming?

Thank you.

If you’re using missionplanner you could write a little iron python script to scale a channel with speed. You could almost do it within the flight controller indirectly, setting up the desired servo on the pitch channel for a gimbal and playing with the max/min etc. This would vary the servo with AoA, which in level flight varies with airspeed (not ground speed).
