This large, impressive plane<\/a> was published in Model Airplane News in 1984. \u00a0It looks like a giant version of the 60 size Super Kaos published in RCM. \u00a0The plan shows a foam wing core fully sheeted with 3\/32\u2033 balsa, with hardwood blocks for landing gear attachment. \u00a0My short kit has a built-up balsa wing with 11 ribs on each side, plus plywood rib reinforcements for the landing gear blocks.<\/p>\n

Leading edge is 3\/8\u2033 balsa. \u00a0Trailing edge is 1\/4\u2033 balsa. \u00a0Spars are 3\/8\u2033 x 1\/2\u2033 hard wood, either spruce or bass. Landing gear blocks are 1\u2033 x 1\/2\u2033 hard wood, 6 inches long. \u00a0Please specify nose wheel or tail wheel when ordering, so I can cut the correct ribs. \u00a0 When you build your wings, the rib spacing is as follows. \u00a0Starting at the root, the\u00a0space between the first two ribs is 2.25 inches, the next space is 2.5, then 3, then 3 again, then 4 for the remainder of the spaces. \u00a0You can get the plan printed, and draw the wing rib locations on the plan if you think it would help.<\/p>\n

The ribs are sized for 3\/32\u2033 sheeting. \u00a0Scaling the dimensions up from\u00a0the 59\u2033 Super Kaos plan, the trailing edge sheeting would be 2 1\/4\u2033 wide. \u00a0Leading edge sheeting extends from the leading edge stick to the spar. \u00a0Or you could just go all out and sheet the whole wing for extra strength.<\/p>\n

The fuselage top is labeled 3\/8\u2033 balsa on the plan. \u00a0It will be cut from two layers of 3\/16 to be laminated by the builder. \u00a0Also,\u00a0it is split into a front piece and a rear piece, because the total length of this part is 55 inches. \u00a0The joint is staggered for extra strength.<\/p>\n

You build the horizontal stabilizer. \u00a0I supply the fin, rudder, and elevators, all to be laminated from parts half as thick as noted on the plan. \u00a0But there\u2019s something funny about the plan. \u00a0It shows the stabilizer saddle cut into the fuselage sides, because the stabilizer at 7\/16\u2033 thickness is thicker than the top fuselage longeron, which is 3\/8\u2033. \u00a0So far so good, but the plan directs the builder to cut the elevators and the filler block between the elevators from 1\/2\u2033 balsa. \u00a0I can cut them from two layers of 1\/4\u2033, which means you laminate them and sand 1\/16\u2033 away, or I can cut them from one layer of 3\/16\u2033 and one of 1\/4\u2033. \u00a0You laminate them and they will be the correct thickness. \u00a0Sounds like a better option to me, so this is what I\u2019ll do unless you have a better idea.<\/p>\n

One other thing: \u00a0Maybe you\u2019ll tilt your engine sideways, inverted, or whatever. \u00a0So you\u2019re on your own with the cowl.<\/p>\n","protected":false},"excerpt":{"rendered":"
