Give me a few sentences and I'll explain what I mean. First off when you say that you're confident your CG is correct, are you using the CG in the manual? I ask prior to making this statement...most manufacturers and absolutely EVERY FW edf that I've purchased and flown has a CG recommendation 7 to 25mm further forward than the ACTUAL CG. This is due, my personal opinion, so that the novice among us are guaranteed to have a nose heavy aircraft to prevent stalling. I can count the FW edfs I don't own on one hand and still have fingers left over, so I don't make this comment casually, yes I'm aware of my addiction lol.
A nose heavy acft and a tail heavy acft have 1 thing in common, incorrect CG. Your test of sitting the F-86 on it's tail and lifting it an inch before it rotates to on it's own isn't a bad place to start CG wise for your maiden. But it's still a nose heavy bird with that CG. Move the battery back until you can set her on her tail, with her canopy on and at the slightest movement of you lifting the tail, she rotates on all 3 gear by herself.
I agree that with all your cosmetic enhancements you might have changed where to place the battery significantly. But the airframe aerodynamically is the same, the CG procedure I described to you is also the same, and will give you the correct CG for your Sabre.
