Before Starting Assembly 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. If you find any damaged or missing parts, contact the place of purchase. If you find any wrinkles in the covering, use a heat gun or covering iron to remove them. Use caution while working around areas where the colors overlap to prevent separating the colors.
Section 1: Attaching the Wing to the Fuselage Required Parts • Wing • 1/4" x 13/4" wing dowel • 1/4-20 x 2" nylon bolt • Fuselage Required Tools and Adhesives • 6-minute epoxy • Sandpaper • Flat blade screwdriver Step 1 Locate the 1/4" x 13/4" wing dowel. Sand a small taper on one end of the dowel to make it easier to attach the wing to the fuselage. Step 2 Glue the dowel into the wing using 6-minute epoxy. Make sure there is about 1/2" of the dowel exposed. 6 Step 3 Place the wing onto the fuselage.
Section 2: Installing the Horizontal Stabilizer Required Parts • Wing • Horizontal stabilizer • Fuselage • Elevator joiner wire Required Tools and Adhesives • Flat blade screwdriver • Sandpaper • Felt-tipped pen • Paper towel • Rubbing alcohol Step 2 Check the distance from each stab tip to each wing tip. These measurements must also be equal. B B' Step 1 Slide the stab into the slot in the fuselage, with the leading edge pushed forward in the slot.
Section 2: Installing the Horizontal Stabilizer Step 4 Use a felt-tipped pen to trace the outline of the fuselage on the top and bottom of the stab. Note: DO NOT cut into the underlying wood. Let the knife “float” across the covering. Cutting into the wood will weaken the stabilizer and may cause it to fail in flight. Hint: You can use a soldering iron instead of a hobby knife to remove the covering. Doing so will eliminate accidentally cutting into the stabilizer.
Section 2: Installing the Horizontal Stabilizer Step 7 Slide the stabilizer from the fuselage far enough to expose the uncovered area. Mix 1/2 ounce of 30minute 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. Remove any excess epoxy using a paper towel and rubbing alcohol.
Section 3: Installing the Vertical Stabilizer Step 2 Check the alignment between the fin and stab. The fin must be 90-degrees to the stab to be in alignment. Sand the opening in the fuselage if necessary to get the perfect alignment. Step 3 Trace the outline of the fuselage onto the fin. Step 4 Remove the covering 1/16" below the line drawn in the last step. Step 5 Mix 1/2 ounce of 30-minute epoxy.
Section 4: Installing the Ailerons Required Parts • Wing • Aileron (left and right) • CA hinge (8) Required Tools and Adhesives • Thin CA • T-Pins Step 3 Slide the aileron and wing together. The gap between the aileron and wing should be infinitely small, approximately 1/64". Step 1 Locate 8 of the CA hinges. Place a T-pin in the center of four of the hinges. Hint: Be careful of the T-Pins, as they can be sharp. Step 2 Place the hinges in the precut slots in the aileron (or wing if you prefer).
Section 4: Installing the Ailerons Step 5 Remove the T-Pins and apply thin CA to each hinge. Make sure the hinge is fully saturated with CA. Use a paper towel and CA remover/debonder to clean up any excess CA from the wing and/or aileron. Step 6 Firmly grasp the wing and aileron and gently pull on the aileron to ensure the hinges are secure and cannot be pulled apart. Use caution when gripping the wing and aileron to avoid crushing the structure.
Section 5: Installing the Elevators Required Parts • Fuselage assembly • Elevator (left and right) • Elevator joiner wire • CA hinge (6) Step 3 Locate three CA hinges. Place a T-pin in the center of the hinges. Place the hinges into the elevator half. Required Tools and Adhesives • Thin CA • T-Pins • 30-minute epoxy • Sandpaper • Drill • Drill bit: 9/64" • Ruler Step 1 Locate one of the elevator halves.
Section 5: Installing the Elevators Note: You can combine the previous step with the following step if you like. This will hold the elevator in position while the epoxy cures. Step 6 Check to make sure the elevator moves freely. It should not rub against the stabilizer at the tip. Check to make sure the hinge gap between the elevator and stabilizer is roughly 1/64". Apply thin CA to both sides of the hinge. Make sure to saturate the hinge and don’t use accelerator.
Section 5: Installing the Elevators Step 8 Hold the remaining elevator in position against the stabilizer. Mark the location of the elevator joiner wire onto the elevator. Step 9 Drill the location marked in the previous step using a 9/64" drill bit. Step 10 Repeat Steps 2 through 7 to install the remaining elevator half.
Section 6: Installing the Tail Wheel Step 2 Cut a groove from the hole to the bottom of the rudder. This is necessary to provide clearance for the tail wheel bearing. Step 3 Test fit the tail wheel bracket into the rudder. Make sure there is plenty of clearance for the bracket bushing and that the hole has been drilled deep enough to fit the tail wheel wire. Step 4 Cut a slot in the aft end of the fuselage for the tail wheel bearing using a hinging tool or hobby knife.
Section 7: Installing the Rudder Required Parts • Fuselage assembly • CA hinge (3) • Rudder Required Tools and Adhesives • Thin CA • T-Pins • 6-minute epoxy Step 1 Locate the last three CA hinges, and place T-pins in the center like we have done for the ailerons and elevator. Step 2 Install the hinges in the rudder. Step 4 Mix 1/2 ounce of 6-minute epoxy. Remove the rudder, and place the epoxy only in the hole, not in the groove. Epoxy in the groove will probably make it difficult to use the rudder.
Section 8A: Engine Installation Required Parts • Fuselage assembly • 8-32 x 3/4" screw (4) • 3mm x 20mm screw (4) • Engine mount (2) • 3mm washer (4) • 3mm lock nut (4) Step 3 Mark the locations for the engine mounting bolts. Required Tools and Adhesives • Drill • Drill bit: 9/64" • Engine • Pliers • Clamp • Phillips screwdriver (large) Step 1 Attach the engine mount to the firewall using four 8-32 x 3/4" screws. Step 2 Position the engine on the mount.
Section 8B: Electric Motor Installation Required Parts • Fuselage Required Tools and Adhesives • Electric motor (Hacker C50 10L recommended) • Electronic speed control (Hacker master 70-3P) • Heat shrink • 8-32 lock nut (8) • 8-32 x 12” threaded rod (2) • 8-32 nut (4) • #8 washer (12) • Plywood (4” x 12” x 1/8”) • Electrical connectors • Propeller (APC 16x12E) There are numerous ways to convert your Twist™ to electric power.
Step 7 Attach the motor to the motor mount plate. Step 8 Thread an 8-32 nut and #8 washers onto each of the threaded rods. Slide the motor and mount onto the rods. Position the motor so the drive washer will be 4-1/4” forward of the firewall. Secure the plate using 8-32 lock nuts and #8 washers after making sure it is parallel to the firewall. Use 5-minute epoxy to glue the mount plate to the sides of the fuselage. Step 9 Select a propeller appropriate for your motor system.
Section 9: Throttle Pushrod Installation Required Parts • Fuselage assembly • 101/8" outer pushrod tube • 145/8" pushrod wire • Clevis • Clevis retainer Required Tools and Adhesives • Drill • Drill bit: 5/32" • Medium CA • Sandpaper Step 2 Test fit the throttle pushrod tube through the firewall, through former 2, and into the fuselage. Once satisfied with the fit, roughen the tube using sandpaper. Slide the tube back into position and use medium CA to glue it to the firewall and former 2.
Section 9: Throttle Pushrod Installation Step 3 Slide a clevis retainer onto a nylon clevis. Thread a clevis onto a 145/8" wire, a minimum of 10 turns. Step 4 Attach the clevis to the throttle arm on the carburetor. Slide the pushrod wire into the pushrod tube and re-install the engine. Bend the pushrod if necessary so it moves freely.
Section 10: Fuel Tank Assembly Step 2 Locate the rubber stopper. Insert one of the metal fuel tubes into one of the holes in the stopper so that an equal amount of tube extends from each side of the stopper. This tube will be the fuel tank pickup that provides fuel to the engine. Step 3 Slide the smaller cap over the tube on the smaller end of the rubber stopper. This end will be inserted into the fuel tank. The larger cap is placed on the side of the rubber stopper that makes the cap.
Section 10: Fuel Tank Assembly Step 6 Locate the short piece of silicone fuel tubing and the fuel tank clunk. Install the clunk onto one end of the silicone tubing. Slide the silicone tubing (end opposite the clunk) onto the fuel tank pickup tube (straight tube) in the stopper. Step 7 Carefully insert the stopper assembly into the fuel tank. Note the position of the vent tube; it must be up at the top portion of the fuel tank to function properly. (Hint: The fuel tank is taller than it is wide.
Section 11: Fuel Tank Installation Required Parts • Fuselage assembly • Fuel tank assembly • Fuel tubing (red and green) Required Tools and Adhesives • Foam: 1/2" Step 3 Install the fuel tank into the fuselage. Make any necessary supports to keep the tank from moving during flight. Step 1 Glue a piece of 1/2" foam to the sides of the fuel tank compartment.
Section 12: Landing Gear Installation Required Parts • Fuselage assembly • 23/4" wheel (2) • 5/32" x 1" axle w/nut (2) • 1" wheel • 5/32" wheel collar (2) • Landing gear • 8-32 x 1/2" screw (2) • 3mm x 5mm screw (2) • 1/16" wheel collar w/set screw Step 3 Attach the wheel to the axle using a wheel collar and 3mm x 5mm screw.
Section 13: Radio Installation Required Parts • Fuselage assembly • Servo w/hardware (5) • Wing assembly Required Tools and Adhesives • Drill • Drill bit: 1/16" • Phillips screwdriver (small) • Servo extension – 12" (2) Step 1 Install the recommended servo hardware (grommets and eyelets) supplied with your radio system onto five servos (elevator, rudder, throttle, and aileron (2). Hint: Place a drop of thin CA onto each screw hole to harden the wood around the hole.
Section 13: Radio Installation Step 7 Temporarily install the aileron servo and mark the locations for the servo screws using a felt-tipped pen. Step 8 Remove the servos and drill the holes for the servo mounting screws using a 1/16" drill bit. Photo for Step 9 Step 10 Tie the string onto the servo extension. Gently pull the extension through the wing using the string. Untie the string when the servo lead has been pulled through.
Section 13: Radio Installation Step 12 Secure the throttle servo using the screws supplied with the servo. Step 14 Temporarily mount the receiver and battery into the fuselage. It may be necessary to relocate the battery forward or aft to balance the model as described in the section "Control Throws and Center of Gravity." Plug in any servo leads or extensions at this time and connect any extensions necessary for the aileron servos.
Section 14: Linkage Installation Required Parts • Fuselage assembly • 43/8" pushrod wire (2) • 105/8" pushrod wire (2) • Nylon wire keeper (5) • Nylon control horn (4) • 2-56 x 1/2" screw (12) • Wing assembly • Nylon clevis (4) • Clevis retainer (4) Step 3 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 14: Linkage Installation Step 5 Place 2–3 drops of thin CA into the hole to harden the wood. Repeat this for each of the three holes. Step 7 Center the elevator servo electronically using the radio system. Install a servo arm onto the elevator servo. Attach the pushrod with clevis to the control horn. Physically place the elevator control surface in neutral. Mark the pushrod where it crosses the holes in the servo arm.
Section 14: Linkage Installation Step 9 Cut the wire 3/8" above the bend. Step 12 Slide a clevis retainer onto a nylon clevis. Thread a clevis onto a 43/8" wire a minimum of 10 turns. Step 13 Remove the back plate from a control horn using side cutters or a sharp hobby knife. 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.
Section 14: Linkage Installation Step 18 Center the aileron servo electronically using the radio system. Install a servo arm onto the aileron servo. Attach the pushrod with clevis to the control horn. Physically place the aileron control surface in neutral. Mark the pushrod where it crosses the holes in the servo arm. Step 19 Bend the wire 90-degrees at the mark made in the previous step. Cut the wire 3/8" above the bend. Step 20 Slide the wire through the outer hole in the aileron servo arm.
Section 14: Linkage Installation 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. Step 25 Secure the throttle pushrod to the servo arm using a nylon wire keeper. Install the throttle servo arm screw when complete.
Section 15: Canopy Installation Step 3 Use a hobby knife and scissors to trim the canopy along the lines drawn in the previous step. Step 4 Position the canopy back onto the fuselage. Trace around the canopy and onto the fuselage using a felt-tipped pen. Step 5 Lightly sand the inside edge of the canopy and slightly inside the line drawn on the hatch using medium sandpaper. Step 6 Apply a bead of RCZ56 Canopy Glue (ZINJ5007) around the inside edge of the canopy. Position the canopy onto the hatch.
Adjusting the Engine Step 1 Completely read the instructions included with your engine and follow the recommended break-in procedure. Step 3 Before you fly, be sure that your engine idles reliably, transitions and runs at all throttle settings. Only when this is achieved should any plane be considered ready for flight. Step 2 At the field, adjust the engine to a slightly rich setting at full throttle and adjust the idle and lowspeed needle so that a consistent idle is achieved.
Preflight Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases the radio should be charged the night before going out flying. Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the correct direction and with the recommended throws).
