I was wondering if anyone was having the same problem Im having with the Free software (not FMA). I cant remember the name of it, it's the heli software that has the Trex and no volume. Its A great sim, however Im having an issue with it. When I move the right stick left it gives some slight colletive pitch (helicopter goes up)and I have to lower my left stick some to correct this(less throttle). Also it's just the opposite when I move the right stick to the right, I have to give it more throttle. I have calibrated this over and over and have got into the mapping on the sim to fine tune it, but Im still having this problem. Im using my stock Wfly radio witch is pretty much the same as a futaba 6. This is making it more difficult for me to try to lean to fly inverted. Im use to it flying upright and know how to adjust, but inverted forget it. Can someone help me please. I really like this software, just need to know if I can correct this problem. Thanks in advance.
