Build your kit and put it on the shelf to look at. Yes some folks have made these small kits Radio controled but these are very experianced builders and flyers! Retracts? Not on so small a plane. Electric is a lot better chioce for such a small plane also. "Bigger is better" Easier to build and to fly. 6 foot wingspan is a nice size to learn with and you can use electric ,glo or gas. Graduate to smaller(harder to fly) planes after you learn to fly larger ones.
