You can by your DLG model or you can make one yourself. Making it yourself is the most fun. A lot of people have asked about how much you save by making your own gliders in composite. The straight answer is that making you own composite gliders are more expensive than buying them and it takes more time to build them than it would take for you to earn that extra money you need to buy one. If you build your own composite gliders you do it because you have to and because you want to. When you have considered this and still want to you have to get something that most likely are not in the normal workshop.
