Thanks Ken for the kind words. OK now I totally get it on the trimotor thing and I think what you are going for is what I call a Characture airplane and not really ment to represent anything. I have done some along that line of thought and you know what I think that kind of ship can be totally cool. Ya go for it a big tri/bi plane really offers a ton of cool things to dream up.
I am thinking a ship of that size three 15/20's would work out just fine but the only problem with that is there are simply not many left in that displacement and likely choice would be the OS LA-15.
You know one of my dream projects and I know I am not likely to ever get to but that does not mean I can thourghly dream up the design. An that is the only Caproni CA-60 with nine wings (a triple set of triplanes) no tail surfaces (pitch and roll controlled by wing surfaces) an eight engines, Oh yea its a flying boat.
