You might want to look a the H9 Alpha (or Arrow) package. Personnally IMHO I think that is the way to go. I have taught on the PTS P-51 package, but the Alpha works out a lot better for both the student and me as an instuctor. As you progress, you can always buy a PTS P-51 ARF (about $120) as a second plane and transfer all your radio and engine to that.
