RE: 3D
If you want to learn get a bigger plane more to crash that way. But the bigger the easier also. Something like an Eratix. It is great at 3D lands very gentle and you can start out 3 mistakes high and learn. Cost is up there for an Elec. but man it is a great 3D plane and very forgiving while flying as long as your high up. With any 3D close to the ground means your just a few feet from crash site lol. Maybe a profile of some sort would be good to learn. When I started I went big and never looked back. Tried the small balsa 3D planes and they are built so light that you can break them just picking them up. And about any small bump will break something. Just try to make sure you have very light wing load and wide ail, rudd, and elev. controls. on whatever. The electronics will work i guess in another plane. Not sure the servos would have the correct tork for 3D. Try it and see and report back.
