Helo's, at least simulation helo's, are much harder to fly and require much more concentration. You have to be on your toe's at all times to fly the machine, and then add that you have to fight the machine.....both offensively and defensively. It is an absolute kick in the southside, though and very challenging. Vortex Ring, Blade Stall, all the fun stuff that can put you in the ground with a big bang are terms you will become familiar with. I would suggest getting a hold of EECH and EEAH to get you immersed into Helo Simulation flying.
