Ok, another question if you would indulge me.
I have read a few books about helicopter flying, particularly in Vietnam.
'Chickenhawk' was just brilliant.
If I remember correctly there was a twist grip throttle control on the collective to control engine speed on the UH1
Is this still the convention on modern helicopters. Do you 'throttle up and down' with a twist grip or does one just set the engine speed in a 'detent' and leave it alone ?
