Add the leading edge stock after the basic frame is done as the stock is inserted in a rotated fashion. Add the wing tips and align the front tip along the center of the leading edge. Sand the leading edge stock to be rounded and meet the ribs. Wing Construction Detail FUSELAGE CONSTRUCTION The fuselage is built as two separate box structures, the front sheet area and the rear built up section, which are then joined over the plan. This system not only keeps each stage simple, but it also helps to ensure a straight fuselage.

Use the brass hub for alignment. Epoxy the hubs in place and add a sufficient amount of epoxy around the base of the hub to reinforce the connection of the hub to the ply. Plywood reinforcing hubs are provided that are to slip over the brass tubing as shown. Alternatively, gluing an additional ½” square piece of scrap 1/8” balsa with a hole drilled in the center can be substituted. Next, CA glue the neoprene cording together to from a “tire”. Use thin CA sparingly as the CA bonds very aggressively to the rubber. Press the CA wetted ends Tail Surface Construction Detail together for an instant bond. The best way to align the ends is to glue them while they are in place on the wheel. Then attach the tires to the wheels and CA in place. A thin bead of CA around the rim makes for a secure tire. Paper cones are cut out. Use a ballpoint pen to score each line on the back to make an impression of “spokes”. It is helpful to do this operation on a paper tablet so that the pen makes a good crease. Fold the paper along the crease lines to exaggerate the raised lines. One of the sections forming a wedge is cut out. Make cuts to the center of the circle along a pair of the spokes. Close the paper cut‐out to form a cone and tape the joint inside the cone. Assembly Sand and dry fit to make the interplane struts. Be sure to mirror the opposing struts for proper wing installation. COVERING Any lightweight covering material can be used. Polyspan makes a good choice Litespan is also popular. This prototype was covered in Polyspan and painted with ...

Motor and Gearbox Tips The Mini‐Olympus gearbox is very durable and reliable but it does have a few weak points. 1) There is often flashing on the gears making rough spots or binding which robs power. Take a sharp Exacto knife and remove this until your gearbox turns smoothly. 2) Excess flashing also occurs where the motor is mounted that makes alignment poor and again robs power. Take the Exacto and carve away this excess until the motor fits easily. 3) Loose set screws on the main shaft and motor let power slip away. Tighten all these set screws ...
