Every other part will be "upside down" for better parts fit. These parts are shown below with x's in them. STEP 2: Glue the "...
- Page 10 STEP 4: Glue the " Balsa parts for the fuselage sides, top, and bottom together, as shown below, with thin CA. STEP 5: Test fit the pylon into the fuselage top sheet. Sand the sides of the pylon, if necessary, so it fits through the slot smoothly.
- Page 11 STEP 8: Press the 1/8" Lt. Ply F1 part onto the pylon (with the engraved text to the FRONT) and then press the pylon assembly onto the crutch. The engraved "TOP" on the crutch should, of course, be on the top. Do NOT glue them together yet.
- Page 12 STEP 10: Press the sides onto the pylon/crutch assembly. Holding everything together, making SURE that all parts are fully pressed into place, secure all joints with some thin CA. Do NOT glue the fuselage sides together at the rear. STEP 11: Press the 3/32" balsa F3, F4, and F5 formers into the fuselage sides with the engraved TEXT FACING FORWARD.
- Page 13 STEP 12: Slide the balsa fuselage top over the crutch and into place on all the formers and fuselage sides. Press the 3/32" balsa F6 and F6B parts in place. STEP 13: Press the 3/32" balsa hatch shelf in place. MAKE SURE that it is fully pressed into place and glue it with thin CA.
- Page 14 STEP 15: Glue the 3/32" balsa hatch onto the 3/32" balsa hatch braces, as shown. Use thick CA or a slower setting glue. Use a weight to hold the bend in the hatch while the glue dries. Glue in the 1/16" plywood hatch latches in place, as shown.
- Page 15 STEP 19: Glue the 1/8" Lt. Ply landing gear mount assembly onto the firewal, as shown. Make sure that the holes line up! STEP 20: Install and glue the pushrod housings, in the fuselage, in the locations shown on the plan sheet.
- Page 16 STEP 23: Glue together one 3/32" balsa W17 and one 1/32" plywood W17P parts together, using the 1/8" holes and 1/8" dowels for alignment. Repeat this, with the plywood on the OTHER side, so you have a left AND right. W17P W17P STEP 24: Repeat step 23, using the W18 and W18P parts.
- Page 17 STEP 26: Press the 1/8" balsa trailing edge, W37 in place. Make sure the ribs are pressed all the way into the slots. Do not glue it yet. Press the 1/8" balsa W25 spar cap in place. Do NOT glue it yet. STEP 27: Press the 1/16"...
- Page 18 STEP 28: Press the 1/16" balsa leading edge support, W28 in place. Do this just a little at a time on each rib. work from one end to the other and then back again. Sliding it in just a little at a time keeps you from breaking it. Slide the 3/16" balsa leading edge, W29 in place, followed by W30.
- Page 19 STEP 30: Glue the 1/16" plywood WJ1 in place, as shown below. Do NOT get extra glue inside this part, as the wing joiner slides in here. Glue the 1/16" plywood WJ2 on the back of WJ1, once again, being VERY careful to not get glue inside the joiner area.
- Page 20 STEP 33: Press WS2 into W26, as shown below. MAKE SURE you use the right side of W26, so the ribs line up with the notches in W26. Also, do not forve the fit. If it's a bit tight, "pinch" the balsa tabs and then they'll fit better. Slide the ribs onto the main Spar, as shown below.
- Page 21 STEP 35: Press the 1/16" balsa leading edge supports, W31 and W32 in place. Do this just a little at a time on each rib. work from one end to the other and then back again. Sliding it in just a little at a time keeps you from breaking it. Slide the 3/16"...
- Page 22 STEP 37: Glue the 1/16" plywood WJ3 in place, as shown below. Do NOT get extra glue inside this part, as the wing joiner slides in here. Glue the 1/16" plywood WJ4 on the back of WJ1, once again, being VERY careful to not get glue inside the joiner area.
- Page 23 STEP 39: Place another magnet on each of the ones you just glued in place. Use a marker and mark the end of the magnets. This is so you don't glue the magnets into the tip panels in reverse, on accident. Trust me, they're a pain to get out if you glue them in the wrong way! STEP 40: Glue the magnets you marked in step 40 into the tip panels.
- Page 24 STEP 42: Sand the leading edges at the wing tips to shape, as shown on the plans. Sand the wing leading edge to the profile shown. To prevent the sandpaper from digging into the ribs and breaking them, put some blue painters tape across the ribs to protect them. Finish sand the rest of the wing with 320 or 400 grit sandpaper.
- Page 25 STEP 44: Protect the plans by laying down clear plastic wrap over them. Build the tails over the plans, using thin CA on all the joints. STEP 45: Lightly sand the tail parts. You can round the OUTSIDE edges of the parts if you'd like, for a nicer looking finished model.
- Page 26 STEP 47: Cover all the parts with a lightweight covering film, such as So-Lite. Do NOT use heavier films such as MonoKote, UltraCote SolarCote, etc., as the shrinkage of these films can damage the lightweight structure of this model. They also add a lot more weight, which you absolutely do not want. If you have not covered a model before, please read the instructions that come with your covering.
- Page 27 STEP 51: Remove any covering from the parts where they contact and will be glued to other parts, with a SHARP X-Acto blade, being careful not to cut into the wood itself. STEP 52: Glue the pylon parts together, using thick CA or a thin application of 5-minute epoxy.
- Page 28 STEP 57: Bend the " landing gear wire, as shown on the plan sheet. The axles are longer than needed, to allow for different, BIG wheels, if you decide to do so. Press the landing gear wire into the fuselage, followed by the 1/8"...
- Page 29 STEP 59: Glue the motor mount together, as shown in the drawings to the left. The parts are cut so they can only fit together the right way. STEP 60: Install the remaining 4 4-40 T-Nuts into the back of the motor mount.
- Page 30 STEP 63: Glue the plastic control horns into the rudder and elevator, as shown. Hinge line STEP 64: Trim off the ends of the ribbed control horn post to be flush with the control surface. Hinge line STEP 65: Insert the elevator control horn through the hole in the fuselage top and slide it onto the elevator pushrod Z-bend.
- Page 31 STEP 66: Glue the vertical fin to the stab, making sure that the fin is perpendicular to the stab and is fully seated. You can use thick CA or a THIN application of epoxy. The 2 tabs on the vertical will be sticking out the bottom of the stab.
- Page 32 STEP 69: Hinge the rudder to the vertical with tape, the same way you did the elevator. Carbon Rods STEP 70: Glue each carbon tube into the slot in the pylon with a SMALL amount of epoxy. STEP 71: Set the control throws as follows: LOW RATES: Rudder: 1"...
- Page 33 STEP 71: Mount the battery, RX, and ESC in the fuselage with the double sided velcro, included in this kit, as shown on the plans. STEP 72: Install the wing, using 6 of the included rubber bands. Make sure the wing is centered on the pylon.
