Ok, got my CG machine. Nice little tool, seems to take very accurate measurements. Here is a picture of the airplane with the 3oz weight on the back set up for exactly 3.5":



This doesn't add up, when I did it on my finger tips it was dead level now on the balance which I trust a bit more, it's nose down, yet it flew nose up.

I did find that my ailerons where a little bit up when I took out a straight edge like adstott suggested so I can only guess that that is the problem.

I also got a incidence meter so I'll check all of those values later when I get time.

So what do you guys think, little nose heavy now? Should I add even more weight?

Also, there is a tiny little bit of fuel in the tank, the stuff my clunk can't reach when draining the fuel tank, is that going to make much difference?
