Probaly explains the pucker tucker associated with the feed back forces of trying to go right way up after rolling a '47 way too quickly - either way.
Either the light weight or heavy weight blades will do it especially when fitted with the Texas No-bar kit, and very especially on the heavy weight blades '47 3B1 etc. with the Texas kit. I.E. stab bar removed, makes them almost identical to the 206 in feel.
letting off pressure when it is trying to roll itself upside down at thirty feet is NOT an option.
Never tried it in a 206 and don't intend to, but probably would not be as bad as shorter blades would make for a lot less leverage, me thinks.
