Status: offline 		I have a question about the CG location. I balanced the plane at the recommended CG location which states hang a wire around the center top wing tube. When I did that it looks as if you need to add allot of lead to the front to get it to balance. I have a DA 100 installed in it. So when I flew the plane balanced at this location it immediately was nose heavy so I started taking out weight, Now according to the CG location it is now tail heavy but still fly’s with up trim and when inverted at a 45 degree angle go up it tucks down like it is still nose heave. So with this where should this plane balance? I also noticed that when you set the lower wing a Zero the Stab is sitting at about +4 degrees Up at the leading edge Is this also correct?

Status: offline 		Well, I figured it out this past weekend on the CG location for my 33% Ultimate. This plane has a wide range on the CG location. It ended up moving it back about an inch aft of the top wing tube and now it fly's much better. It will now stay on track on an upward climb inverted an not fall off an all the up trim needed before has been taken out.
