3D,
Thats fine, I'm more than happy to hear your opinion. Your right about guarding the switches though - they should be! I'm actually an advocate of puting more switches on the collective - but on a propper thumb pad to allow pilot to minimise hands-off time.
Given the ristrictions within the R22 for space etc and more importantly cost considerations stiffening the switch is a pretty sensible approach to inadvertent actuation I feel.
Also, with regards the fact that the R22 has a tail rotor drive shaft whirl resonnance at about 134% RRPM that can and has destroyed tail booms I wouldn't like to be the one that had to take my hand of the throttle in the event of a governor runaway failure in flight!!!
Just a thought.
