I find Aerofly Pro is super for nearly everything -- especially harriers.

However, I can't seem to modify any of the Aerofly planes (I've tried for many days with the Extra and Cap) to get them to tumble like some of the planes on Realflight (Edge, Pitts, Sukhoi).

The big planes on Aerofly pro seem to be "filled with helium". I get an effect like I'm flying under water, as it seems to take forever to initiate a snap or any stalling maneuver, or get the plane to fall realistically. I think this is why they're so forgiving in harrier type moves. I've added weight, changed the sim speed, increased throws, added power. I didn't play with airfoils or incidences.

Now, i find it's really more fun to fly the RF, (especially with others online, which Aerofly Pro will NOT do), so I use Aerofly Pro only when I need to work on inverted harrier practice.
