What can you do when the blades start sailing? Quite a bit actually. You fly the blades to keep the disc horizontal – the cyclic position is not the issue, it is the plane of the disc that is maintained using the cyclic. I don’t know anything about the Robo, but this technique is used in the Huey and Kiowa. As for rotor brakes, in my experience (limited Blackhawk, quite a bit of Squirrel) the brake is very effective and provided you apply early (within limits), are within engine shutdown wind limits – I have never come close to a problem.
