"I did a little research

US 35 wt 68oz HP 2.4
OS BGX wt 60 oz HP 4.1
Fuji 32 BT-32A wt 60oz. HP 2.2
Zenoah G38 wt 71 oz. HP 2.5

Engines I have
MVVS 1.6 wt 38 oz HP 3.0
BME 44 wt 46 oz HP (I don't know, but it is the most powerful)

I figured if I was going to add weight in the nose anyway, I might as well go with the BME. Plus, I really wanted to save the MVVS for a Cap 232. "

How did you come to the above conclusion, if you didn't know where the CG belonged ? ? ?
