On helis if you have your stick on 11? if you have tracking then the one blade will give you 9? and the other 11 thats a problem..!
Pa something isn't right. In your original post you said that 'all' of your props were bad. There is something going on perhaps with the balancer that you are using. I've had a couple of props out of about 3 sets (24 total) that I was unable to balance. Never noticed a tracking issue and some of them were perfectly balanced. Since so may folks including Tabb fly with the APC sets would hate for you to spend money on wood props only to find out that it something else in your balancing workflow that is causing the issue. What balancer are you using?
I I am using the Dubro... But i have the top flite too but on balancing it isnt good...! I think that i have to go with XOar
For what it's worth, I've got about 30 APC props from QC (for two C8) and I've balanced them all. All of them needed some balancing -- not much, but some. All were tracking properly -- I place the props on a flat surface and measure the vertical tip displacement. Andy
