I had the same problem with my Funtana 125G , I changed the CG half way between the forward and aft CG specs and it still will drop the tail a bit but once you give it a bump of down elevator it will settle out and level off, once it does it's a matter of a delicate topuch in that you will have to just bump some up elevator rather than pull and hold the elevator and she'll grease right in 3 points everytime, some guys have posted in the forum regarding this problem with this plane and they actually went in and Mcguyvered up an adjustable AOA rig on the wing , So if my lil pea brain interpreted what I read in those posts, the problem with the 125G dropping the tail when landing is an Angle Of Attack issue with the wing, I just changed the cg to neutral and give it a bump or 2 of down elevator to level it off then just bump some up elevator to grease it in
