.10 Engine

If you are in a club which will provide you with an instructor I do not recommend such a small plane. No instructor will look forward to flying anything that diverges much from the usual .40 size trainer. The smallest size I would recommend to use is the Sig LT-25 which is a superb kit and gentle flying plane. Try not to get far from mainstream practices if you want to learn to fly RC with minimal pain.
