Absolute RC Heli Sim is a free app that you can use to "test fly" several RC helis. Actually, in the free version you can only test one, the Blade, which is something very similar to the "toy" RC Heli you can buy in a mall for $25, but this one actually cost $125, and is MUCH BETTER (but similar sized).
This has multiple "fields" you can test fly on, and you can choose multiple view points. The NORMAL one is is the stationary one: you stand still and the chopper moves. It gets difficult as you lose track of the heli's orientation. You need a big screen.
On the other hand, the graphics are quite good, as they're based on 360 "skybox" of real places.
There are other fields and other choppers available, but those are extra cost.
The freebie is definitely worth a try.
