RE: It's coming for AFPD, new patch, new feature!
Greg the answer to your question is yes. I'm sure with today's technology and PPS's out there it will be easily done with the weight of the Monsoon or Slow Ride.
No problem ....
I think that is what your question is asking to Lego ... when will PPS no longer work on an airplane. The problem that somebody is going to have to overcome is inertia. Airplanes are designed to fly forward meaning you'll need more power to stop and airplane then to fly an airplane, unlike a heli. A heli has very little aerodynamics so it gets all it's lift from the giant rotors. The reason why you can make a helicopter move so quickly in any direction (3D, 4D or whatever you want to call it) is because of the size of the rotor (what we airplane guys call props). I would say that it's going to be a long time before you see a 40% Edge hold reverse pitch tail up at the field because of the weight mass to prop ratio. Where on a helicopter the rotors sometimes twice as long as the heli.
Now this is all going to be determined on who is brave enough to risk their planes and who is not ... but will be fun to watch who takes it to the highest level.
