Got to make two flights on my UCD 46 this afternoon. WOW ! I love this plane. I am very happy with this combo. I need to move the CG back some more. I have it at 5 1/4 trying to be conservative I want it to 3D well but don't wan't it to be too much of a hand full landing. My tank is on the CG so it stays where I set it. My question is with all this in mind where does everyone thing I should be. what the sweet spot if you will.
