If your plane is nose heavy it makes it more difficult to Flair at landing. Try reballancing your plane first to see exactly where your cg is.. then maybe move it 1/4 inch back at a time to see how it lands.

I played around with my TF Sea Fury and the CG a little. This plane lands so well and has a nice two wheel roll out before the tail slowly settles. After a dumb thumb move and a rebuild the plane landing was not as smooth and was difficult to run out on those mains. I thought CG! After some changes to CG, little changes to performance. The cowl was not fitting well so I rechecked the thrust. I found the engine almost 1/4 inch lower than the recomended thrust line. Fixed that and it makes me look like I know what I'm doing again. CG had little effect even when moved 1/2 inch. Thrust made a world of difference.
