Here's my storch, just before its maiden today:
I tried to make my own steerable tail wheel, but gave up after a couple of failed attempts and just purchased one. Other than one of the wheels falling off at take off, it flew great! I'm a complete novice, and between my tiny trainer, mini guinea, and this beast, I found the storch to be the easiest to fly. Very slow, and very stable.
I'm using just the half-length ailerons, as I might add the separate flaps at a later time.
