A strange comment.

Aerofly Delux Pro and prior versions didn't model most second and alll third order effects.

The newest version, 5.5 finally corrects this and now is getting very similiar to Realflight's better physics modeling.

Heli's in AF5.5 are still lacking but 5.5 is a definite improvement... helis in RF are far more accurate.

If you apply the standard FAI trimming and tuning rules to planes in both sims, the lack of nuances really stand out in prior versions of AF.
The planes used to fly like they were on rails, with improper wing stall charactersitics, poor post stall, torque effects, etc...,

Aerofly completely redid the physics engine in 5.x to fix these issues.... yet some it seems think prior versions "the best physics engine"?

I suggest you upgrade.


I haven't just "flown all of the sims" I own them ALL as well.

BTW: I like AF 5.5 a LOT, but features, ease of editing, etc. still put RF in the lead, even if the physics were identical.
