I'm Scratch bulding a Learjet and plan on using 2 d/f the plane is going to be about 6' in legenth the fusalage will have a radius of 110mm and i have yet to scal down the wing span but my question is will 2 .46 fans be power enough or should i go all out and get 2 .91 the plane is going to have a fiberglass fuse and a wood and foam wing and elevator. plan on also having alot of scale detail like flaps and spoilers so that would add weight but again (2) .46 or (2) .91 and if you know of any d/f manufactures could you please let me know by sending a url

Thanks
Adam
