RE: 40% 260 on a Diet
I look at this with great "enthusiasm" as I take great lengths to realistically remove weight from my builds. The light side of a 40% Carden 260 is 37lbs with a DA150 with canisters. This plane can and has been done lighter but I think 37 a realistic light plane. Canisters add roughly 1-1/2 lbs. A DA 100 for all practical purposes weighs 6lbs and the 150 about 8lbs. Looking at this projected 28 lbs makes me wonder...37lbs minus canisters 1-1/2 minus 2lb engine weight comes to 34lbs with cowl mufflers. This leaves 6 lbs of wood and foam to remove from a already considerable light plane considering this was from a 37lb reference. How did you come to the 28lb target weight???This plane takes 29 sheets of sheeting to do the wings. Cardens stock for sheeting is roughly 1oz per sheet. Lets not sheet the wings so there's another 29oz's or 1lb 13 oz's. Still got 4 lbs to go from an already light number with no sheeting on the wings period..I wonder???Have you calculated this number out or is it just a guessed target..Regards Walt
