In spite of the suggestion, by one of the more mischievous members of the group, that I should have designed the model and passed out the kits without testing it simply to enjoy the chaos that resulted I spent some time testing it. The flying characteristics of the OD-17 indoors did not satisfy me. For a "generic airplane" (That's what one of the O.F.F.C. members said I should call it.) it required a little too much effort to trim. It had a bit of a tip stall in a tight turn when the power ran down. Suspecting that the 12% airfoil that is used was to blame I redrew the wing with a 10% airfoil and added a little more dihedral. I built the new wing, yesterday, and tested it this morning. Voila! Outdoors and indoors it simply flies. The design is finalized and as soon as I have the instructions edited on the plan the kit will be available. The first dozen kits are for the O.F.F.C. members (The contest is at the end of October.) then it will be available on my web site. There are two more similarly constructed models on the "drawing board".
