Another point on making choppers easier to fly. You need to have a good fine control throttle to act as a collective pitch lever. I was able to make my own ( as I'm using analogue controls thro the gameport rather than USB) from a 100k potentiometer.
You need to calibrate the throttle so that it only travels through about 60 degrees from off to full, preferably from horizontal to up like a real collective.
There is an article on simviation somewhere advising on how to fly choppers in FS2000 (advice applies to all MS sims). The advised controller sensitivity and null point settings are very good and still work well in fixed wing aircraft.
If you understand how rotary wing craft work you should then be able to fly most choppers well with difficulty level set to medium after alittle practice.
