I am conscious of how obvious is what follows: “be afraid of every gram put behind the CG”.
In my C III, despite of over 250 grams of the dummy Mercedes; of an entirely of copper “shoehorn” exhaust for the certain not light Laser 90, to balance I was forced to put a lot of lead (550 grams!) in the nose.
I have this very same fear and I think I need to see what possible weight savings are possible at every step of the rear construction (and the tail construction). I'm planning to cut down the ply doubler (as most of it, honestly, isn't needed) and it's probably a good idea to use 1/64 ply at least for the rear part of the fuselage. I may also see whether there's any "fat" to be trimmed off the forward fuse now that it's all locked together.
