This Schleicher ASK 21 is a two seat trainer glider, capable of cross country flight and acrobatics. This was designed by Rudolf Kaiser replacing the old ASK 13. I built this plane pretty much to scale, and the flight characteristics are somewhat close, I spent a lot of hours building this airplane. It has a cockpit and if you want to raise the canopy (usually you have to raise each canopy separatly but in this one the canopy is just one big piece) Activate group 1 and   use the vtol slider to open and close the canopy. Activate group 2 to and use the vtol slider to put down the speed brakes - NOTE the speed brakes dont actually do anything - I dont think but there are actual brakes if you want them. -ENJOY I put the COG back a bit, which makes the glider fly better, but that makes the flight characteristics a bit off. The Fox bat doesnt fly very well, and if it lacks power use the overload editor and ajust it. I am ery proud of this airplane enjoy:)
