Not a new concept in flying training!
Too many years ago my first Chipmunk QFI, guessing correctly that my fist was performing destructive crush testing on the top of that lovely aircraft's control column, came out with the memorable "Don't hang onto it like a trapeze artist with no safety net, hold it like a princess holds a navvy's cock-between the finger and thumb of your right hand!"
After that my efforts improved sufficient to leave me currently playing with the yoke of the"NG" 18,000+ hours later.
Is this any help..................................?
