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. Welders glue is used exclusively for this build, except for the control rod ends, which are glued with thin CA.
Page 9 Carefully align the spar slots. While maintaining alignment, bring the two halves together and press firmly. STEP 2 STEP 2 STEP 2 STEP 2 Remove the support tabs from the spar slots. Rev: 2013.02.02.v001b...
Page 10 Locate the wing spars, check their fit into the slots. Coat both sides of the short spar with a bead of Welders. Insert the spar into the forward slot, spreading it a little as you go to help the glue get all the way in. Rev: 2013.02.02.v001b...
Page 11 Coat both sides of the long spar with a bead of Welders. Insert the spar into the rearward slot, spreading it a little as you go to help the glue get all the way in. Press the foam against the spar to secure the bond.
Page 12 Wipe off any extra glue from both sides Use some tape (high tack tape shown) or other means to maintain pressure on the glue joint while it cures Add some weights to hold everything flat while the glue dries. Rev: 2013.02.02.v001b...
Page 13 STEP 3 STEP 3 STEP 3 STEP 3 Locate the wood control horns. Complete the pre-made slot in the Elevon so that it extends all the way through Test fit the horn. Rev: 2013.02.02.v001b...
Page 14 Coat both sides of the horn with Welders. Lay a small bead of Welders into the slot. Install the horn into the Elevon, make special note to line up the profile of the horn with the profile of the hinge slot as shown.
Page 15 Wipe off any excess glue. Repeat for the other Elevon. Let everything dry. Apply weights to help keep things flat. STEP 4 STEP 4 STEP 4 STEP 4 Locate the items shown. Rev: 2013.02.02.v001b...
Page 16 Slide the z-bend and shrink tubing onto one of the carbon push rods Heat shrink the very end only. Apply a few drops of CA down the open end of the heat shrink tubing. Rev: 2013.02.02.v001b...
Page 17 Shrink the tube completely. Apply heat carefully and blot away any CA that is forced out, onto a paper towel. If the glue catches fire remove the lighter and blow out.

Page 20 Attach the quick link to the Servo arms. For the arms included with the Twisted Hobbys CS-40D, use one hole in for mild control (shown) and outer most hole for extreme control On a piece of cardboard or other soft surface push the pin onto the keeper.
Page 21 PREPARE SERVOS PREPARE SERVOS PREPARE SERVOS PREPARE SERVOS Add thin (skim) layer of Welders to the three sides of the Servos that come into contact with the surfaces of the cutouts in the wing. NOTE: The method being described will allow for removal of the servos yet hold them tight otherwise.
Page 22 Smooth the glue out to a thin coat and allow to dry a couple hours, longer if possible. NOTE: Once the glue has dried, there will still be a “sticky” surface between the servos and wing cut out, hold them securely in place, but still remove-able if needed STEP 5 5 5 5...
Page 23 Trace the location of the doubler Coat each surface with a thin coat of Welders Allow the glue to tack up. Rev: 2013.02.02.v001b...
Page 24 Bring piece together, remembering to keep the back edges flush. Completed assembly. If the glue on the servos and wing has dried, you can now install them into the wing cutouts. Servo horns should be sticking out on the bottom side. NOTE: Install these in the same positions as when you did your initial radio setup earlier in the build.
Page 25 Both Servos in position Decide what batteries you will be using. Mark as required for the foam that needs to be removed. Rev: 2013.02.02.v001b...
Page 26 Remove the material as marked and test fit the battery STEP 6 STEP 6 STEP 6 STEP 6 Locate the upper and lower center ribs. Test fit the upper rib, making sure that the back edge lines up with the cut out in the wing.
Page 27 Test fit the lower rear rib. NOTE: This part is NOT symmetrical make sure it is orientation is such that the back edge lines up with the cut out in the wing. Glue all the pieces together (wet) and secure with pins or tap. Allow to dry. Locate the motor mount Rev: 2013.02.02.v001b...

Page 29 Coat the mating surface for the motor mount on the fuselage with Welders, and allow to tack up. Once the glue has tacked up, assemble the two pieces. Motor mount installed and ready for the motor to be installed. Rev: 2013.02.02.v001b...
Page 30 STEP 7 STEP 7 STEP 7 STEP 7 Locate push rods that were assembled with ends earlier Install the z-bend end into the Elevon Horn. With Elevon it’s neutral position, rough cut the push rod to approx. ¼ inch beyond the quick link. Rev: 2013.02.02.v001b...
Page 31 Push back the Elevon and slide the cut end of the push rod thru the quick link. It may be necessary to cut the rod a little shorter. Lightly tighten the set screw. NOTE: Over tightening will crush the carbon rod and ruin your push rod. Repeat for the other side.

Page 33 Test fit noting that the larger surface area is the top of the rudder. Lay down a bead of Welders on both sides of the wing in the area that comes into contact with the rudder. Avoid the area directly around the servo, this will make it easier to remove should it fail.
Page 34 The glue will tack pretty quickly, but until it does, make there are no gaps. Repeat the process for the SFG’s. Test fit. Rev: 2013.02.02.v001b...
Page 35 Apply a small bead of Welders in the are the SFG will contact. Install check squareness. Repeat for the other side. Make note of where the Center of Gravity should be located. C.G. = 13mm C.G. = 13mm C.G. = 13mm C.G.
Page 36 If using all the Twisted Hobbys’ stuff, and the 250mAh Twisted Hobbys’ LiPo battery, your ESC and Receiver should be located approx as shown in regards to the front to back position.
Page 37 Bottom side. For this build we chose to keep all the electronics on the top in order keep them save during landings. …………….. READY SET GO! ENJOY! Rev: 2013.02.02.v001b...

Page 42: Tips And Tricks
TIPS AND TRICKS TIPS AND TRICKS TIPS AND TRICKS TIPS AND TRICKS - A good building surface is “drop ceiling” panel from a local hardware store on a nice flat board - use parchment paper between the areas being glued and your work surface - heavy flat objects (like books, batteries, etc.) could be used to hold everything flat - When resetting your radio, start with all the ATV’s or throw volumes at 100%.
