Yep. I've been running the numbers in my head. The twin engine option saves me about 10 ounces that would be centered about four or five inches behind the cg. Also a small servo plus linkage, about a half ounce. A lighter structure with no firewall, at least another ounce. Fuel system - maybe 2 ounces empty (mostly at the cg). Probably at least 12 ounces out of the nose. If two engines will fly it I don't see how I can justify the third engine (I would love to hear three Saito 30s humming along slightly out of phase!).

The Sikorsly Ilya Mourometz was another one that I considered but I don't think I could possibly balance it. In fact, I don't know how it flew. They had crewmen way back in the aft part of the fuse. THe tail area is huge and the engines sit just about on the cg. Very short nose. Must have hired pilots from teh Sumo Wrestling corps!

THanks for all the help.
