OK. This is what I recommend solely because it's what I did and I'm very happy with the results. It's one of my favorite planes in the hanger.

Plane (kit)
Tower Trainer 40

Plane (ARF)
Hobbico Avistar - if you want to get in the air quick, the instructors in my club highly recommend this plane. I don't have one, myself.

Radio
Futaba 6xAS - The six channel is more than the trainer needs but trust me. I bought my trainer with a standard four channel and it was sold shortly after I started collecting more planes. The 6xAS is a very capable computer radio with 6 model memory.

Engine
Magnum XLS-46A - The OS FX46 is a good engine also. I have both and the Magnum way outperforms the OS. Make sure you don't get the old Magnum XL-46A. It's also a good engine but no where near the performance of the new XLS-46A.

Being new to the hobby when I bought my Tower Trainer and wanting to do it right, it took me a solid seven weeks to assemble. That was when I was unemployed so it probably would have taken longer if I had a job.
