Hi Chuck,
That's really funny that you contacted me about this because when I was guesstimating where my CG would fall using the 6cyl 220 Franklin engine, someone gave me your W&B numbers for your fixed Tri-gear. 1275 #'s EW if I recall.
To answer your question, my 2STD CG ended up being right on the dot. See the attached.
I thought that the airplane would be nose heavy from the 6 cyl engine so I moved it as aft as I could and used a 29# Whirlwind 151 CS prop. Battery on the FW. I have the Super II horizontal and I moved my wing aft. SL 30, transponder, audio panel, Trio Pro, AFS 4500 panel. Full conformal foam (heavy) upholstery, floorboards in baggage (makes it flat).
I built it as an FT with all the hardpoints and FW beefing for the nose gear trunnion. And then I got over all the fear-mongering re the TD (always my first choice) and found some Grove aluminum TD gear in Barnstormers for a song and converted.
I weighed control surfaces before and after painting with Southern Polyurethane single stage white, topped with clear and the difference was just a few ounces. I can't imagine paint on the whole plane amounting to more than 15#'s or so.
Hope this helps.
Best,
John
