Got another tank today! i'm compressing the updated video and I can say to squinty1 that this actually has some 3D in it. You can tell by how i struggle to hover it that i don't have enough authority in the tail surfaces (because its too nose heavy) I'm going to move it back tonight, fly tomorrow and give an actual cg reading where i end up. I think the parachutes and harriers are going to be much better with a further back cg as i'm using all my elev. right now and feel like i need more. This airplane rocks. 2 gallons burned now.
