For what it's worth, I'd like to see a few more multi-rotor models added to RC7. It seems there are more and more of them coming out every day. I recently got a Yuneec Typhoon 500+ and would really like to be able to drive a virtual version of it in RC7 during our long, cold off season here in Illinois.
(I tried Yuneec's UAV Pilot sim, but had to return it due to the virus warnings when I tried to run it. Just not willing to take the risk.)
Since FPV drone racing is becoming more popular, that might also be something else to be added to the sim in future versions.
