RE: Open Source Scratch Build?
Not a huge amount of time this evening, but I just had to start getting the 3-View printed out. I didn't get the files posted but will try again tomorrow. I don't have a large format printer/plotter, but will start with pieced together tiled prints.
Here is the first 16 pages, only 80 more to go not counting ribs and other stuff. I will be adding as I go, feel free to contibute.
On an engine note, with the ultra narrow nose of this aircraft, an RCV SP would fit nicely. Tubig's Spitfire thread has some good ideas on cooling. Do you think a SP120 would be enough horse power for this bird? Would look really cool with a 16" three blade, though a two-blade would be more scale? It's 3.11" with the nose being about 4.5".
But though a 4S would have more torque and I know warbid guys like them. A GMS 1.20 Humming at 13,000 would produce an engine pitch at about 13,000rpms / 60 seconds = 216 Cycle/Second and the AM-35A Mikulin V-12 would have produced 2200 RPMs = 1100 Exhaust strokes/Minute * 12 cylinders = 13200 Exhause firings/minute or 220 Cycles/Second. Thats 792 Khz for the AM-35A and 780 Khz for the GMS 1.20. And with a good Pits muffler it will be throaty.
Here is the first of the 3-View.
