RE: So you've decided to Build a Seagull PC-9?
Bill,
Sounds great. Pretty much all the improvements that I had done, but rather than springing for carbon rods, I just used the supplied rods and ran the ends through guide tubes where they exit the fuse. I had a .61 in it and never had any flutter problems. I'm curious as to hw your aileron response will be after cutting them for your flaps. I used flaperons through mixing, but after a few flights, never used them as it sets up a nice stable final approach without them. What ebgine are you using?
