As with most ARFs, it seems they always put a fuse former/bulkhead AT the CG, thereby making tank installation impractical, at best. I'm leaving it up front because I want to run muffler pressure, and the Uniflow tank system. With a pump, it adds more weight, and can get into a richening situation with the stock ST carb. There will be some trim changes, but not so much....probably could go with a 6 oz tank, if you wanted...or just fill the stock tank only partially. It ain't gonna take much fuel with this setup, I am quite sure.

I have 8231's in ailerons, fit just fine...same with fuse servos. The cutouts are "standard" and the JR servos fit no problem.
