RE: trainers
Fred, You're getting some good advice here if you'll listen. Since you're a new member with just 6 posts, I'm assuming you're a newby looking for your first plane so the advice boils down to "Don't get either! Get a traditional trainer!" You'll learn to fly quicker and better with a good trainer plane and an instructor/buddy box setup and the inevitable crash will not set you back so badly. In our club, the Hobbico Avistar 40 has been popular and a lot of guys have learned to fly with it. It's also a great flying plane for fun flys and fairly aerobatic and can do the novice pattern, especially with a powerful .46. The "Select" package with the radio and motor already installed, will get you in the air quickly for about $280, but it's just a simple 4 chan Tx and a smaller motor that's fine for learning but a little weak for aerobatics. Tower will let you build a "custom combo deal" with the Avistar ARF kit, OS .46AX, and their 6chan, 6 memory, computer radio for $348.
Also, I just got a new trainer (don't ask what happened to my Avistar); a World Models Sky Raider I for $70. I want to have a trainer ready for my nephews, friends, and their kids, so I thought I'd try this cheapy. I've had good experiences with World Models and it looks like this one will be no exception. It goes together fast and flys great as a trainer. It's got a semi-symtrical airfoil like the Avistar, the wings a little bigger by about 150 sq in., the hinges are already glued in, and the tail feathers just screw on. The only problem is the color scheme is a gaudy blue and white checkerboard with the blue squares being a gradient pattern. The overall effect is perfect for fading away in the clouds, so be sure and get the one with a bright red or yellow tail.
I've seen both the PTS F22 and P51 fly; the F22 didn't have the slow down mods on and it was a hand full, especially in a cross wind. The P51 had the mods on and flew OK, but was prone to ground loops on the runway. It would probably be a pretty good flying (without the slow down mods ) and looking plane for a 2nd or 3rd plane, but definitely not a trainer in that config.
Hope this helps and you have a successful start in RC!
P.S.
Get a regular trainer first.
