. Well, if you're flying with an 'underslung' rotorhead (typical of the early Bells) it can be a matter of .. contol input .. go make a 'cuppa' .. corresponding reaction to airframe occurs.
It seems it is the main diffeculty in flying because I cant imagine just how hard it must be to fly a sensitive bird that responds 2 seconds after your input.
That sounds like another early Bell (2 second delay).
But if you want to know what is feels like to fly a truly responsive aircraft can I recommend the 500D. With a new head (ie. everything still tight) the aircraft tends to respond in close correlation to one's thoughts!
You move the cyclic .. and the craft is already there! A brilliant piece of engineering by the original Hughes company.
