Small planes can be more difficult to fly.

Teaching yourself to fly can be done but is usually more expensive and time consuming.

If you post your location here I'm sure someone will be able to direct you to help that is closer.

Did you go to a hobby store usually they can help you get in touch with a club.

One last thing parkflyers and glow powered planes are much different in terms of performance. Learning how to fly the planes I mentioned does NOT mean that you will be skilled enough to fly glow powered planes. I would suggest seeking help BEFORE attempting the transition.
