Does anyone have pictures or a diagram on how they made their linkage for the rotor brake on their Air Command? The AC gyro I just bought has a stock rotor brake mounted but there is no linkage so it cannot be activated from the pilot seat. Before I design and build my own linkage I thought I would ask to see what others have done to solve this problem.

Mine, not an air command is operated in the same manner as a pushbike brake, via a cable.

The Air Command I had did not have linkage. You pushed the stick forward until a bumper contacted the mast just under the brake. This would pivot the brake assembly and apply it. You might be able to zoom in on the picture.

If you zoom in on the picture you will notice I clamped a stiff hose around the bumper to extend it a little and sort of cushion it.

Here's mine. https://photos.app.goo.gl/STPqFWXatcjbjYdh7
I made a bracket out of flat bar with a slight bend in it to clear the head while tilting, then a bracket at the rear to hole the cable.
It's not the best leverage, but it works "ok" . I've come to find out that roto brakes are not for braking, but to hold the rotor while taxiing. It doesn't need to be strong... just strong enough.

Looks good.
