Page 8: The Build
THE BUILD THE BUILD THE BUILD THE BUILD CONSTRUCTION METHODS: Building surface should be at least 2ft x 4ft and flat. Weights or some small heavy objects will be handy for holding things in place during the time glue is setting. Three types of glue are used for the build, Welders glue is use for most areas, Hot Glue for the electronics and CA in the construction of the control rods and stiffners. - Page 9 STEP STEP STEP STEP – – – – C C C C – – – – Locate the wing the wing halves and the fuseslage backbone. Note that there are little tabs that help to position the wing halves correctly. You should be looking at the bottom of the wings, and the cutout for the elevator should be facing down, this...

- Page 12 STEP STEP STEP STEP – – – – E E E E – – – – (con’t) From the underside of the Elevator install the 1x5x245 strip into the precut slot of the fixed part of the elevator so the spar will be flush with the surface.
- Page 13 STEP STEP STEP STEP – – – – F F F F – (con’t) Once the Welders has tacked up, lay both pieces on a piece of either wax or parchment paper, and slide the two pieces together. Use the extreme front and rear of the Canopy corners as a guide to line up with the corners of the cut outs in the Fuselage.
- Page 14 STEP STEP STEP STEP – – – – G G G G – (con’t) Notice that the Stirrups are keyed to the plate and all three parts should fit nicely into the exisitng holes and slot you just made. Also notice that the slot in the Stirrup should be toward the rear of the plane.
- Page 15 STEP STEP STEP STEP – – – – H H H H – Locate the lower part of the Fuselage and test fit into the slots of the belly side of the backbone. Apply a thin layer of Welders to the contact areas of both pieces, and smooth to a thin layer and allow to tack up.
- Page 16 STEP STEP STEP STEP – – – – H H H H – (con’t) With the belly of the plane facing up, test fit the Elevator. Check with a tape measure that when all butted up flush that the tips of the Elevator from both sides are the same distance to the wing tips.
- Page 17 STEP STEP STEP STEP – – – – H H H H – (con’t) Locate the Anti-Torsional strips. For a more streamlined look you can trim and bevel one end of each strip as shown. Tack gluing method will be used to attach the Strips, but in order to get the glue in the right spots, do the followning;...

- Page 22 STEP STEP STEP STEP – – – – L L L L – (con’t) Once the glue on flat surfaces has tacked up, apply Welders to the sides of the tabs and the motor mount than assemble. Check for squareness and tweek from side to side if necessary.
- Page 23 STEP STEP STEP STEP – – – – M M M M – (con’t) Cut horizontal and vertical slits into the bottom of the Rudder control surface to accommodate the tail wheel holder and the bottom rudder hinge. Make sure that there will be enough room for the tail wheel to clear the bottom of the rudder control surface.
- Page 24 STEP STEP STEP STEP – – – – M M M M – (con’t) Remove the Rudder from the fuselage and glue the hinge pieces into their respective places being mindful of their locations as noted in the previous step. Pressure on the glue joints can be maintained with some high tack masking tape.
