Hi Dave

here are some pics about the mod I made. The CG at 215mm still a bit forward, but drop landing had to do with blanked elevator at full flaps- too much exponencial. I used the same expo settings as in the F18 and proved wrong

I plan to move the CG a bit more in the rear at 220mm, maybe even at 230mm. When rolled inverted in other flight (gear retracted), the plane pitched down when inverted, so I guess 225-230mm will be fine. This is a long way from the original 190mm recommended by the manufacturer. No pitch change during flight as "fuel goes by" with tank install near CG. Downside is that main gear doors open because fuse pressure is higher without intake. I have already ordered the BIG Robart cylinders for the job[8D]
