Good choice for a trainer. Motorgliders are very easy to fly and you'll never want to get rid of it. Unlike a "regular" trainer. Building one is simple and straightforward. Not much to guess at. Now, I should tell you that my experience comes secondhand. I saw one go together and saw the guy train on it for a short period of time. (he moved, not crashed) He had an easier time of it than I did with a Sturdy Birdie. While it won't prepare you for the higher speeds of reqular aircraft, you'll have plenty of response time. It should be fun!
