The Storch will fly pretty much in any configuration of straight or not straight. I did reinforce the skinny area of the elevator with a popsicle stick. This seemed to help a lot. Especially when you start using a lot of control inputs, which you will! This plane is fun to throw around once you get the hang of it. Blenders, spins, loops, and sorta rolls are fun. Knife edge is a little impossible due to the diahedral of the wing.
