Hello to all here, this is my first post, although I've been lurking around this forum for over a year now. Well, where to start???? Like everyone else here, my dream is also to build my own plane, but not any plane. So, here is some of the info I gathered, will post more as the thread evolves. Mission: Arctic Flight - From Barrow AK to Helsinki FI [TD="class: vTop fbPhotoUfiCol"]Distance is 3524 miles or 3062 nautical miles or 5761 kilometers. This distance is the theoretical air distance ( great circle distance). This is the shortest theoretical flight path. [/TD] General Characteristics Crew: 1 + one cat Length: 25 ft 11.811023622047173 inches or 7.92 meters Wingspan: 32 ft 9.700787401574757 inches or 10.00 meters Airfoil: TO BE DECIDED Powerplant: Ferrari V12 1985 testarossa ( bought on EBAY, hahaha) Body Type: Monocoque Wing type: Parasol with the classic Cabane struts fuel: Regular gas Fuel capacity: 450 gallons which will equal around 2000 pounds or more Oil capacity: 50 gallons ( yup, keep an eye on that weight) Empty weight: around 2000 pounds ( bit more depending on type of wood) Max take off weight: around 5000 pounds Range: 4500 miles service ceiling: 15000 ft I've been drawing multiple hulls ( hey its a seaplane), but Im stuck trying to find the proper airfoil. Any suggestions? Still have to consider multiple things like wood contraction and expansion on Sub-Arctic and Arctic conditions, weatherize and other wonderful things that make my day such a pleasure. Shall we play?
