I started using this one and it's pretty good! It has an FPV function that makes you believe you're really flying it. The phantom model is a P2 vision and you can tilt the camera! There is a GPS and ATTI mode IOS as well. The physics are realistic so I believe it's a good alternative for rainy days! It works with a dongle , plugged to your remote (Phantom remote don't work, I use a Futaba ) Unfortunately the graphics are way below standard, even at their max, but to learn to fly, I find it brilliant! I have tried the helix (demo) and the phoenix(demo) I don't think they are that good, and they have no FPV. I would be interseted to know if you guys use simulators and wich one you prefer. Thanks.
