I never had an instructor. Here is my four step program:

1) Fly on a simulator (FMS or Clearview) $35
2) Fly a simple 3 channel electric like a GWS Slowstick $30
3) Move up to a foam 4 channel like GWS E-Starter $35
4) Fly a 40 sized Glow plane.
Foam is easier and cheaper to repair than balsa. Electric motors require no tuning. You can learn how to fly on electric power and then add glow engines to the mix when you are comfortable.

Good luck and don't give up.
