The Seafoam is a Ken Willard design published in RCM. \u00a0You\u2019ll find the plan on Outerzone. \u00a0I did this kit in an attempt to make more 10 size glow models available to use all of the 10 size engines that are sitting around with nothing to do.<\/p>\n
The plane got its name from the Midwest foam wing and stabilizer set that was used to build it. \u00a0The original foam wing had an extra thick airfoil to impart greater strength to the wing. \u00a0I reduced the thickness considerably in my kit to reduce drag, as the extra thickness is not needed for strength when building with ribs and spars. \u00a0When building the wing, use 1\/4\u2033 balsa sticks for the leading edge and trailing edge. \u00a0Ailerons are 1\/4\u2033 x 1\u2033 balsa trailing edge stock, or you can attach them to the trailing edge for 3 channel control. \u00a0The wing is to be sheeted with 1\/16\u2033 balsa, either full sheeting or with cap strips on the ribs. \u00a0Use triangle stock on the wing tips to make Hoerner tips for enhanced performance.<\/p>\n
To build the wing, mark the rib locations on your sheeting, lay out a couple of perpendicular lines on a big piece of paper or directly on your table. \u00a0Then stick everything together. \u00a0Don\u2019t worry, it\u2019s really easy.<\/p>\n
The stabilizer saddle is made to accommodate the flat balsa stabilizer included in the kit. \u00a0You should build a hatch on top of the nose section, either for your lipo batteries, or for the servos if flying with a 10 glow engine. For the engine nacelle I have included the 1\/16\u2033 ply bottom, a pair of balsa sides, and a firewall. \u00a0The original plan assumes that you\u2019re going to throw a nacelle together somehow, and old Ken didn\u2019t give much instruction on the matter. \u00a0Even if you leave everything hanging in the breeze it will work, but I trust you to come up with something that satisfies your level of expectation for good looks.<\/p>\n","protected":false},"excerpt":{"rendered":"
