RE: Second plane questions...
Well, it sounds like you are looking for a kit. Any great planes kit will have great directions. A Goldberg Tiger 2 is a good second plane, low wing trainer. The directions are not as good as Great Planes, but they suffice.
If you are looking for an ARF any Hangar 9 ARF will be first rate. I personally went with a Great Planes U-Can-Do 3D 46. It lands a lot better than my trainer and is a great platform for learning Advanced 3D Aerobatics. I enjoy it a lot. VERY easy to fly around the sky not doing 3D.
