The ultimate flap position on the original ASW20 was sometimes referred to as the "Jesus" flap. As I discovered when I first deployed it on mine, that is likely the expletive you will use. Any glider that has flaps that deploy much beyond 45 degrees will display quite different behavior, particularly pitch and attitude that takes some getting used to. Stall/spin behavior also changes and many pilots advise deploying extreme flaps only on final.. I didn't get any instruction, but followed colleagues advice to practice at altitude. Proceed with care!
