Abandoned self propelled Glider with a Trailer for free, sitting for 15 years!

Mark and I look through the German DG-400 powered glider. She’s been in storage for some time but a very low mileage plane with around 100 hours on it. Mark and his dad built a couple kit planes and flew them so he’s my go to guy to get familiar with this unit. Still, we don’t know anything about this here glider and plan to test the systems and see what we have. This is the first real glance at it and assembly of the wings, cleanup etc.
