Field Equipment Required Before Starting Assembly • Propeller (2-stroke (EVO11050) 4-stroke (EVO13080)) • Glow Plug Igniter with Charger (HAN7101) • Fuel • Glow Plug (EVOGP1/HAN3011) • Glow Plug Wrench (HAN2510) • Manual Fuel Pump (HAN118) • 12-Volt Starter (HAN162) Before beginning the assembly of your Twist, remove each part from its bag for inspection. Closely inspect the fuselage, wing panels, rudder, and stabilizer for damage.
Section 1: Attaching the Wing to the Fuselage Section 2: Horizontal Stabilizer Installation Required Parts Required Parts • Wing Step 3 • Fuselage • 1/4 x 1 3/4-inch wing dowel • Wing • Fuselage • Horizontal stabilizer • Elevator joiner wire Required Tools and Adhesives • 1/4-20 x 2-inch nylon bolt Required Tools and Adhesives • 6-minute epoxy Place the wing onto the fuselage. Secure the wing using the 1/4-20 x 2-inch nylon bolt.
Section 2: Horizontal Stabilizer Installation (continued) Step 5 Remove the stab and use a hobby knife with a brand new blade to remove the covering 1/16-inch inside the lines just drawn. Step 7 Slide the stabilizer from the fuselage far enough to expose the uncovered area. Mix 1/2 ounce of 30-minute epoxy. Apply the epoxy to the exposed area on both the top and bottom of the stab. Slide the stab back into position and double-check the alignment of the stab.
Section 4: Ailerons Installation Required Parts • Wing Step 3 • CA hinge (8) • Aileron (left and right) Required Tools and Adhesives • Thin CA Section 4: Ailerons Installation (continued) Slide the aileron and wing together. The gap between the aileron and wing should be infinitely small, approximately 1/64-inch. • T-pins Step 5 Remove the T-pins and apply thin CA to each hinge. Make sure the hinge is fully saturated with CA.
Section 5: Elevators Installation Required Parts Section 5: Elevators Installation (continued) Step 3 • Fuselage assembly • Elevator joiner wire • Elevator (left and right) • CA hinge (6) Required Tools and Adhesives • Thin CA • T-pins • 30-minute epoxy • Sandpaper • Drill • Drill bit: 9/64-inch • Ruler Step 1 Locate three CA hinges. Place a T-pin in the center of the hinges. Place the hinges into the elevator half.
Section 6: Tailwheel Installation Section 7: Rudder Installation Required Parts Required Parts • Rudder Step 3 • Tailwheel assembly Required Tools and Adhesives Mark where you drill the two locations for the tailwheel support.
Section 8: Engine Installation Required Parts Section 9: Throttle Pushrod Installation Step 3 • Fuselage assembly • Engine mount • 4mm x 20mm screw (4) • 4mm washer (4) • 4mm x 25mm screw (4) • 4mm lock nut (4) Mark the locations for the engine mounting bolts. Required Tools and Adhesives • Drill • Drill bit: 11/64-inch (4.5mm) • Engine • Pliers • Clamp • Phillips screwdriver (large) Step 2 Position the engine on the mount.
Section 9: Throttle Pushrod Installation (continued) Step 3 Slide a clevis retainer onto a nylon clevis. Thread a clevis onto a 14 5/8-inch (370mm) wire, a minimum of 10 turns. Section 10: Fuel Tank Installation Required Parts • Fuselage assembly Step 3 • Fuel tank assembly • Fuel tubing (blue) Install the fuel tank into the fuselage. Make any necessary supports to keep the tank from moving during flight.
Section 11: Landing Gear Installation Section 12: Radio Installation Required Parts Required Parts Step 3 • Fuselage assembly • 2 3/4-inch wheel (2) • 4mm x 25mm axle with nut (2) • 1-inch wheel • 4mm wheel collar (2) • Landing gear • 4mm x 20mm screw (4) • Grub screw (2) Attach the wheel to the axle using a wheel collar and grub screw.
Section 12: Radio Installation (continued) Step 8 Remove the servos and drill the holes for the servo mounting screws using a 1/16-inch drill bit. Step 9 Use a piece of string with a small weight (such as a wheel collar) attached as a device to pull the servo lead through the wing. Lower the weight through the servo opening, allowing it to pass through the ribs and out the hole in the center of the wing. Step 10 Tie the string onto the servo extension.
Section 13: Linkage Installation Required Parts Section 13: Linkage Installation (continued) Step 3 • Fuselage assembly • Wing assembly • 4 3/8-inch pushrod wire (2) • Nylon clevis (4) • 10 5/8-inch pushrod wire (2) • Clevis retainer (4) • Nylon wire keeper (5) • Nylon control horn (4) Position the control horn on the elevator so the horn aligns with the hinge line of the elevator. Mark the position for the mounting holes using a felt-tipped pen.
Section 13: Linkage Installation (continued) Step 10 Slide the wire through the hole one in from the end of the elevator servo arm. Secure the wire using a nylon wire keeper. Step 14 Position the control horn on the aileron so the horn aligns with the hinge line of the aileron. Mark the position for the mounting holes using a felt-tipped pen. Section 13: Linkage Installation (continued) Step 18 Center the aileron servo electronically using the radio system. Install a servo arm onto the aileron servo.
Section 13: Linkage Installation (continued) Step 24 Make a 90-degree bend at the mark made in the last step. Temporarily connect the pushrod to the throttle arm. Check the movement of the throttle to verify there is no binding at either low or high throttle. If there is, make the necessary adjustment to eliminate any binding.
Adjusting the Engine Step 1 Completely read the instructions included with your engine and follow the recommended break-in procedure. Step 2 Preflight Step 3 Before you fly, be sure your engine idles reliably, transitions and runs at all throttle settings. Only when this is achieved should any plane be considered ready for flight. At the field, adjust the engine to a slightly rich setting at full throttle and adjust the idle and low-speed needle so that a consistent idle is achieved.
