Wish you good luck and how you go about learning, especially on your own property, is certainly your business. In your very first post you mention some previous figure nines, and later mention 2 channel foamies, then even later discuss co-ordinated turns etc. You obviously have some expereince or exposure to both RC terms and general aviation. How many RC flights have you attempted prior to purchasing the trainer you have now? You obviously have a computer, do you or your son have an RC simulator? Have you set up an RC field on your property, ie a smooth flat well mowed area for take offs and landings. Just curious.
