I have clearveiw and I think it is pretty good for $30.00. It is better than fms and he updates it all the time with free updates for life i don't think you can go wrong. I have fms and the demo for G3 and I just can't see spending that kind of money on a sim. Unless you are really into it. You don't want to spend more than a 1/4 of the cost of you're heli. If you have a grand in you're heli than you had better get G3. I am getting close to that amount. I have upgraded a walkera 60 to a T-REX 450. I have jr xp8103 and receiver an align motor, hs55 servos, 2 2200 mah lipos all I need now is the $130.00 T-rex bare bones kit and I will have my T-rex. I have used the walkera as a demo heli. It has been through many crashes and has taught me alot. The same as a sim will do for you. Try the free than go for the demo from G3. Than buy clearveiw. If you get good and want to start 3d get G3. You will save money with all of them. Just make sure you use you're TX with the sim or at least a controller with joysticks.
