N891JF is right at the forward limit with pilot and full fuel, and I can tell you that I need a lot of UP trim to keep the nose up, but it's a small trim tab and I still have plenty of travel left, so it does work. Forward is certainly better than too far aft, and even though yours has a nosewheel, I wouldn't expect any problems being able to rotate the nose up on takeoff. It's easy enough to move some things aft if needed later, and it's better to start with max stability, rather than min. > Next question: The horizontal engine centerline with the temporary engine > mount is 2.5" below the top of the upper longerons.

Anyone see a problem with that.< My CG is 2.375" below the longerons on N56ML, and it's not a problem at all in any respect with my plane.
