Hey Skipper! Let an experienced pilot check out your glider. You can learn on one, but a trainer is better. The one thing you want to avoid while learning is being dead stick. Especially when learning to land. With a glider, there's no going around again. You can't practice approaches and take off is totally different. With a Trainer, you have more to learn with. I hope you meant a 46 inch glider.

If you have any questions, feel free to ask. Someone will always be around to help out.
By the way .. where are you? Are you close enough to us that we could help in person?
