The Dynam "I can fly" I made mention of in my last post also has a proprietary TX/RX. Has a buddy box/SIM port but I guess you would have to buy another radio to use it.
What I did was take one of my cheap oomodel AR6100 RX and put it in the plane. then I used my DX4e and DX7 to buddy box with. Im sure someone in the club will have 2 spektrum radios and possibly a spare 6100 RX that could be used during the initial training. Then once you solo, switch back over to the RX/TX that came with it. At least that is what I am doing with my friend that I am teaching to fly.
Like I said...the Dynam from nitroplanes does fly like a traditional trainer. Andlike I said, it looks a lot likethe Apprentice, only a tad smaller and its all foam (no plastic cowl). Its a 4 channel with ailerons and flies just like other trainers I have flown...but obviously lighter because its a foamy. Actually was the first foamy trainer I had flown and was impressed with the way it flew. Nice aileron banked turns and the rudder and elevator reacted nice.
For 100 bucks, if you are on a budget...its a winner. Also, this plane flies so slow that buddy boxing isnt totally necessary if flown high enough...but I still recommend buddy boxing till you solo.
