A very affordable stabiliser for RC ‘planes fitted to a rig as tilt axis stabilisation. The first segment is at 0.25x speed so the action of the gyro is (just) visible. I used the elevator channel with the ‘pitch’ gain at about 50%.

Out of the box the performance is way behind the GS1 but this device runs on open source firmware. I’m hopeful new firmware will adapt the device for KAP in time.

Tom Benedict has suggested the possibility of programming it so that the rig can be switched from AutoKAP to RC control using the aux channel in flight. This would be a boon!

Rig with orangey bits on: in this position the ‘rudder’ gyro controls the tilt axis.

At the risk of clogging up the internet with utterly useless video footage this clip shows the motion achieved on the rudder channel. It’s notchy at best and I have had it stick in the nadir axis, almost as if the servo has hit a stop somewhere. I think you can just about pick out the reverse tendency:

Using the servo reverse dip switches doesn’t reverse the gyro action, only the direction of the Tx stick.

If I hook up the Rx3S to the clickPanPro the tilt axis is unable to achieve a horizontal attitude. Clearly there is much more to learn on this!
