Yes...that X bellcrank was somethin else...(but when you thimmmkee' about it...it did have some merit.
However the weirdest...funniest...but most frightening method of controling a stunter was in those early daze when the China-sponsored flyers....started showing up with their little
RING FINGA' AND RING GLOVED ADJUSTABLE FLYING GLOVE HANDLES?
Although they they had 'run away straps....I ALWAYS VISUALIZED WHAT COULD HAVE HAPPENED IF THEY SNAGGED THEIR MODELS ON SOMETHING. and would have to live the rest of their modeling lives with out a fore-or pinky finger???
(forgive the 20 sec. sketch!!! ouch)
