RE: First Plane
Sounds like you have the bases covered, I learned to fly helis and airplanes somewhat simultaniously.
I have had several cheap Walkera's, a Blade CX (first succesfull flights), Blade CP Pro, ECO8, Raptor 60, Hirobo Shuttle, 2 T-Rex 450 XL's, T-Rex 600, HDX-450 (maybe better than a T-Rex) and a JR Venture. A bit carried away? Maybe so I sold most of them and bought a couple of nice airplanes including a Great Planes Super Stearman. I only have the Venture and HDX heli left but am looking for a good deal on a T-Rex SE.
I think the precission needed to fly a heli make me a better airplane pilot. You will catch on fast I am sure.
