...63 flights on my Knife ARF - it's helped me advance quite a bit on my vertical hovering - i don't come close to touching the tail to the ground (and don't ever plan to) but i can now get some pretty long hovers on calm evenings (which was my original purpose in purchasing the Knife) - i can also do some halfway decent low altitude, high-Alpha knife edges with it...

...the problem? - my aileron flutter seems to be getting worse - now i'm getting it even at lower throttle settings - i'm thinking about going to 4-40 linkages on my ailerons - anyone else tried this?...
