Ran some initial numbers on the CG. I am paying for putting 2 servos in the tail as I expected. Fuel and smoke tank will go on CG. I will have to work hard to keep everything as forward as I can. Laying it out as I have done in the spreadsheet brings me to needing 21oz in the nose. I think I can get some stuff further forward than listed but this gives me a good outline of what I am up against.
