I definitely recommend checking the Model Aeronautics Association of Canada (MAAC) site http://maac.ca to see if there is a flying club in your area. Getting "hands on" help is usually better than getting words from a web forum. Many clubs have instructors who will teach you to fly for no charge (other than club membership).

I think I remember seeing articles on simple mods to improve performance but cannot remember if they were in the RCU magazine or somewhere else.
