its 4 ft long 3 ft wide made with fan fold blue foam it started off like a profile plane then i made bulkheads the skined it in foam then 1 3/2 balsa sheet.....im not sure how scale it is just kinda going from pictures tryin to keep it light as possible right now its at (570 g. or 1 lb 4 oz.) dry weight nothing installed....im not sure on the power system yet .....it first started out as i was going to use my 2 64mm powerplant out of my dynam a10 but after doing a quick thrust test i was only getting 10 oz. of thrust per fan..i thinks its only a 330 watt system....so i scraped that idea and ordered a couple other sets of fans to see what i can get out of them (77mm and 89mm) i got a couple sets of motors for each a (420 watt set and a 1300 watt set)and a medly of batteries i still might need to order another battery with a high c rating for the 1300 watt setup.....but the project is on hold till i get my fans from hk for size reference cause i will have to install them before i finsh skinning the bottom of the plane : )
