RE: Which plane for a beginner?
My wife has a Hanger 9 P-51 PTS as I said before. It did not require additional work to put it together or make flight worthy and it's been flying 9 months. The Nexstar is a good choice but if you really want the P-51 then don't be concerned. Like I said before not only will the plane help you advance your skills, it comes with a flight sim.
Our club has a Nexstar that we use to give people intro flights with and my wife has also flown it. She prefers the P-51 PTS. Nexstar or P-51 PTS, pick the one you like, get an instructor and have some fun.
I meant this in reply to MT RC.
