Combat flyers are you listening out there? If you're not flying F.A.I. combat you are missing out on what I feel is the most innovative and outright fun event going. The planes fly extremely well, and if you run a Fox .15 BB it is much less expensive than A.M.A‑style combat. The international rules, if used at the local level at all, are confusing and hard to keep in mind, but even t is can be a lesson in mental concentration.
In this article on my latest design, the Sickle 3, 1 will try to get your enthusiasm going for F.A.I. The plane has 450 sq. in. of area, and should weigh about 14 oz with a Fox, This combination will give you a low enough wing loading for a truly spectacular turning plane. The semi‑elliptical planform seems to handle the turbulent Texas winds (our constant companion) much better than a straight taper wing. The curved leading edge also seemed to be more crash resistant than a straight or tapered wing. I don't know if the reason is that the tips don't hit the ground in a crash or if it is that the built‑in stresses tend to counteract the forces of the sudden stop. I will show you how to make these with very little extra effort, and at a lower cost than using ordinary spar stock. If you are still reading this you must be interested, so let's get ready to make some planes.
