RE: FMS simulator
I have the FMS sim. The problem with it is that it doesn't do rudder turns. It will yaw and come around a little, then pretty much fly straight. Same on the ground. Graphics are not much.
If you are trying to learn to fly using ailerons, it's not bad. Rudder doesn't work too good wether on the ground or in the air. That is with the Cessna 182.
For the price it's not bad. Download it for free. If you have a JR radio, you can plug it into your sound card. If you have a futaba, you can get the pugs and solder a cord together to use it on the sound card.
If you have to buy it, hold on to your money and get the Realflight Sim.
