My hopes are that A2A with the coming release of the C172, will see huge sales from across the board of simmer and flight schools thanks to P3D and all the USB gauges out there made for the C172.
Following that success, they will make a R22 for the same purpose, as the R22 is a great RL trainer for Helos and there are complete flight decks for simpits out there to make the R22 in scale.
I thought about making a C172 simpit after the news release of the A2A update annoucing the GA bird, but just cant give up all the other planes I sim in to having just one flight deck. With the R22 however, I can fly that ANYWHERE let it be bush or international airport and can explore and enjoy great addon fields in detail and up close as I hoover around.
So yes, I do hope that A2A makes a helo and use the R22 as at least one of them as it would have a huge market place in my opinion.
I did all of my flight training on the R22/R44. Great training machines and quite fun to fly. I have now moved on to the 206 and 206LR but i still get to fly the R44 at work every once in a while.
The problem with helicopters in flight sim is depth perception and feel. When you hover, you are looking at references and make inputs based on them. Also you cannot feel the wind in flight sim which also adds to the joys of hovering. Hovering into wind, cross wind and downwind all feel completely different and require different inputs from the cyclic, collective and pedals. Therefore I rarely fly helis in FSX because I can't use my references properly since there is no depth perception along with the fact that I cant feel the wind and the forces that the wind exhibits on my controls.
