im a car guy and dont have planes.
but the illegal part .....i mean i fyou had a couple guys who flew together on some upstate/back woods/farm property i think they could set up a shooting system with out major worries.
i think...remember i dont fly them just watch.

and as far as the trouble with getting someone streaming and then trying to "shoot" them outta the air.
what is you limited the steering so that its easy to lock on and follow someone?
i dont mean just make straight flyers, but just tweaked it so you have a bigger turn radius(right words?)?

can you make a styrofoam plane witha bb shooter in it? that be cheap to shoot down.
dunno just my thought after coming over to the "higher" side of the hobby.-
