OK checked the feathering spindle and main shaft last night - no perceptible run-out. Changed the feathering spindle anyway and also put new plastic blades. Put different colored tape on the new blades so I could see which blade was where, adjusted the blade grip linkage to get them right in line, put 1/4" of cardboard behind the battery to move it forward to compensate for the 2-3 clicks of forward cyclic trim I needed to add (reading about eCCPM adjustments, seems I would have to adjust all 3 servo linkages to adjust the forward cyclic issue, so I took the easy way out!). Anyway, man, what a different flying bird! Not bragging, but hovering it in my 10X11 dining room is a cinch, I can even swing it around like it's on a pendulum, and after the battery wears down a little, it will almost hover hands free!

Guys, learn to trim your heli properly, and I will almost guarantee you will be a better flier - the heli isn't designed to fly anyway - an out of trim situation just multiplies that tendency!
