It is a fun hobby. Here are some hints.
Don't get one of those Cox or other plastic jobs. They are heavy, fly like brick and break easily. ARFs work fine for RC but they are a mess for CL.
CL kits are not hard at all to build. And balsa flies so much better. Worth the trouble all the way.
0.49 engine is okay. They are cheap and require a smaller area. If you can afford an engine about .29 to .35 size, do it. Fly much smoother and are much tighter on the control lines.
Start taking off with about 1/2 a tank until you get used to the dizziness. You will with a little time.
As for flying, just read instructions and try it. It is about impossible to have an instructor fly with you here. It can help with a lot of planes to tune for lower RPMs or put the prop on backwards to fly slower.
Good luck and have fun!
