RE: H9 P-51 PTS
Here's 2 cents worth from someone who bought the PTS as a second airplane. I couldn't buddy box with it, since I had installed the flap servo immediately (didn't use flaps, though). At first I had some problems converting to a taildragger, but they were quickly overcome----with the help of experienced flyers in my club. The most difficult part was mastering approaches and landings with some power as opposed to landing a high wing trike with no power. As for flight, this plane was a piece of cake for me with factory throws, etc.
Now, all the training stuff is off. It has plenty of power and is quite fast with the stock engine and an 11x6 2-blade prop.
Since I had added the flap servo, I recently began using the flaps and now landings are dirt simple....no pun intended.....with just a little throttle management.
I have 70 or 80 flights on this plane, it's still in one piece, and I was (am) a rank beginner when I started flying it.
