Hi all,
its not the first spinning A-Star/helicopter.
Just wondering, if a little modifikation could prevent further accidents like that?
Thinking about a gravity activated engine cut off build in 90 degrees to the horizontal in some distance to the rotor mast - with a calculated/tested load for something like around 1 turn per second - which will be well outside the normal flying envelope.
May be a time delay could also be integrated - say 2 to 3 seconds, to make sure, the helicopter is really spinning out of pilot control?
Would give a higher survivability on the ground - and leaves you with autorotation in the air - which might be acceptable.
Any suggestions?
