RE: need to learn flat spins
Just be very careful doing the blender (where you're going strait down and "put em to the antenna and in"). I almost completly killed one of my planes. I had a little too much speed and was going strait down and moved the sticks in to start the flat-spin. When I landed, part of the fuse, and wing were a little cracked.
If you have too much speed, then you can just start to bury the grave for the plane!!
