Wombat! I solved my problem! I also posted the solution [link=http://www.rcgroups.com/forums/showthread.php?t=410632]here[/link]. I'm assuming it's a "new" type of sticky collective problem... well, as far as I know anyway. The flybar was catching on my center hub (but only under tension as if the motor was running) which was locking the whole rotor head to the center hub and effectively muting collective inputs. Otherwise, the collective felt as smooth as butter when just testing it by hand on the bench.
I'm yet to fly on it (fixed at night), but I can tell just holding it in my hand and running the pitch range that she'll fly like a banshee now. I'm so happy! Can't wait to try my first 3D maneuvers! .. and go thru another self-taught crash-course in heli piloting
