RE: Looking for small, first 4 Ch plane
The best piece of advise everyone will give you, is to hold onto your money and find a local club.
Go out to their training sessions and see how you like the club and field.
If you do, join up and take the training.
Hang around and learn.
You'll change your choices very quickly once you start picking up pointers, do's and don'ts that you will not pick up by yourself.
You may find a GREAT deal on a nice setup too!
