Seawind (oz14280)

About this Plan

Seawind. Radio contro sport seaplane model, for electric power.

Quote: "Get your feet wet in electric seaplanes with this homebuilt-like pusher, designed for 12-cell power systems. Seawind, by Laddie Mikulasko.

Each summer, a number of modelers have the opportunity to spend some of their vacation time near water. In many instances, they wish they had brought along a seaplane to fly. The electric-powered Seawind is well-suited to take along on such trips, or just for relaxed weekend flying at the local lake. The model is simple to build - and can also be flown from land, by using the simple two-wheel main landing gear.

The Seawind has good handling characteristics both on the water and in the air. It is mildly aerobatic, and being electric powered, can be flown practically anywhere without concern of annoying anyone with the racket from an internal combustion engine. The motor in my prototype is a geared Astro 15 running backwards and tuming a 12x5 tractor prop, powered by twelve 1400 mAH Sanyo SCR cells. Motor control isvia a Horak electronic throttle.

As with any electric, a light-weight structure is a must for good performance. Use only the lightest balsa you can find, and do not omit the weight-saving cutouts in the various parts as indicated on the plan.

Wing: The wing is built in two halves, which are joined later. Pin the bottom main spar and trailing edge to the building board, directly over the plan. Insert all the ribs and glue them in place. Insert and glue the top spar and the leading edge. Sand the leading and trailing edges to the contour of the ribs. Glue on the top leading edge and trailing edge sheeting. Glue cap strips to the ribs as indicated.

When dry, remove the wing panel from the building board and flip it over. Block up the trailing edge and securethe wing to the building board with pins. Sand a gentle curve into the bottom wing spar and trailing edge between ribs W1 and W2, as shown on the plan, so that both pieces are flush with the bottom of W1. This done, glue on the bottom trailing and leadingedge sheeting and capstrips, and sheet the area where the sponsons are located. Set aside this half of the wing and build the other half to the same stage..."
