In my opinion the jokers who design most helicopter cockpits made damn sure they never had to fly in them.
The older 206 models are particularly vile for anyone over 6ft.(I hadn't realised the more compact amongst us, Whirlygirl, also had a problem) There is NEVER enough pedal adjustment despite the fact that it would cost peanuts to provide more screwthread and detachable "turn-around" pedals. An idea for one of the accessory manufacturers perhaps?
