Tired of waiting for FT, I built the Hanger Simple Stik in a 115% version, which seemed like a pretty good size to me. At 115% the channel cuts weren't much bigger than the foam thickness, so I just fudged the size down a little. This size gave me a 42" wingspan at the leading edge which would allow me to use a stock FT Stik wing sometime in the future if the plans ever come out. After reading about others problems with CG, I moved the tail servos forward and moved the wing back a little. I also used CF pushrods to reduce tail weight. In this configuration the CG was right on one of the CG marks with a 1300 3s all the way forward. There were two different CG marks on the plans so I took the conservative route and went for the forward one which looked OK to me.
On its maiden flight it flew pretty well. The roll rate was sufficiently sporty and the handling was predictable with one exception. In an outside loop, the plane showed a reluctance to make the inverted up turn to complete the loop. I thought that might have been a pushrod wow issue so I added a few more pushrod guides to keep it straight. After testing it, the problem persisted, so I am going to try moving the CG back a bit on the theory that the plane is a little nose heavy and can't lift the nose well when inverted. If that doesn't help, I kind of think it might be the flat bottom wing not performing so well when inverted. Any thoughts?
