Contents of Kit Preflight As a large model, the airplane is critical of proper battery use, control linkage setups and flying techniques. Please pay particular attention to the following areas. Maintain the proper mechanical advantage on all control surface linkages. Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the correct direction and with the recommended throws). Test run the engine and make sure it transitions smoothly from idle to full throttle and back. Also ensure the engine is tuned according to the manufacturer s instructions, and it will run consistently and constantly at full throttle when adjusted. Check all the control horns, servo horns, and clevises to make sure they are secure and in good condition. Replace any items that would be considered questionable. Failure of any of these components in flight would mean the loss of your airplane. Never attempt to make full throttle dives! Large models perform much more like full-size airplane than small models. If the airframe goes too fast, such as in a high throttle dive, it may fail. The model should be flown like a full-scale airplane. Throttle management is absolutely necessary. Hardware checks Double-check the setscrews in all control horns to be sure they are very tight. Periodically check these to be sure they have not loosened over time. Always use threadlock on metal-to-metal fasteners. Receiver Battery Selection Be sure adequate batteries are used to power the receiver. It is recommended that two identical 6-volt receiver packs are used. Each pack must have a minimum of 2700mAh capacity. Use packs of 3000mAh when super high torque servos are used. Range check Always range check the radio system per the manufacturer's instructions before the initial test flight and periodically afterward. Check the voltage of the on-board packs ALWAYS use an ESV with a 1-amp load to check the receiver battery packs and the ignition pack before each and every flight. If there is any doubt that the packs are questionable, DO NOT FLY until the packs are recharged. Front Landing Gear Cover for T-28 Trojan 2 19

5 Recommended Center of Gravity (CG) Additional Required Items Correctly balancing the model is critical to its performance and flight characteristics. Checking the balance on this model is best done with two people. Measure back 25%-28% of the whole wing root s length from the leading edge and mark the CG range with a felt-tipped pen at the wing tip. This is the recommended center of gravity (CG) range. Fully assemble the model. With a helper, lift the airplane with your index fingers to find the balance point. The balance point (CG) should lie between the two marks on the wing. If not, try to move some parts such as batteries to different position, or add the necessary weight to the nose or tail to obtain the correct balance. CG Radio Equipment 7-channel radio system (minimum) 3 standard servos 8 hi-torque servos Recommended Engines R-45 AEROVATE 45CC Propeller (consult engine instructions) Servo Extensions Y-Harness Adhesives 6-minute epoxy 30-minute epoxy Thick CA glue Threadlock Servo Selection Tools Adjustable wrench (small) Drill (drill press preferred) Hook and loop straps Foam Hex wrench Hobby knife Phillips screwdriver (small) Pliers Scissors Square Measuring device (e.g. ruler, tape measure) The servos used for the control surfaces of this model must have a minimum of 9kg-cm (125 oz-in) of servo torque. The servos with metal gear are strongly recommended. Before Starting Assembly Before beginning the assembly of the model, 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. 18 3

6 Section 1 Aileron Servo and Control Horn Installation Wing panel (left and right) Aileron (left and right) Attach the servo arm to the servo when the servo is centered. Locate the two hard wood blocks for mounting the servo. Use the servo and two blocks to measure the correct position for the blocks on the aileron servo cover. Mark the position with a pen. Glue the blocks to the servo cover with epoxy at the marked position. After the epoxy is fully cured, secure each block to the cover with a wood screw. Install the servo to the mounting blocks with provided screws. Plug a servo extension onto the servo. Tie the servo leads together by using a secure connector, or using a ribbon to prevent them from coming loose during flight. Tie a weight to a piece of string. A wheel collar works great in this application. Tie the other end of the string to the servo extension. Lower the weight into the wing from the aileron servo opening. Let the weight drop out through the opening near the wing root for the servo. Use the string to pull the servo lead through the wing. Step 6 Install the aileron servo cover with servo to the servo opening with four screws. Section 11 Canopy Installation Fuselage Canopy The canopy are pre-cut to fit the fuselage. Position the canopy on the fuselage and secure it using provided screws. Radio Setup A 7-channel or greater computer radio is highly recommended. This allows the following features: Mixing the right aileron to the left aileron (flaperon mix) Electronically adjustable aileron differential Mixing the right elevator to the left elevator (dual elevator mixing) Independent travel and trim adjustments of each elevator half When you use a 7-channel or greater computer radio, each servo is plugged into its own separate channel. Consult your radio manual for specific details on hookup and programming. Control Throws The following is our recommended control throws for your reference. Step 7 Locate the hard wood mounting position for the control horn on the aileron in line with the servo arm. Install the control horn to the position using the provided screws. Step 8 Repeat Steps 1 through 7 for the remaining wing panel. 4 17

7 Step 6 Secure the tail hook hatch cover onto the fuselage with provided screws. Section 10 Wing Installation Wing panels Fuselage V wing pin Locate the V wing pin and carefully slide half of it into one wing panel. Section 2 Hinging and Sealing the Control Surfaces Wing panel (left and right) Aileron (left and right) Properly hinging the control surfaces on this model is very important! Poorly installed hinges affect the model s precision and control response and can also be dangerous. Each and every hinge needs to be securely bonded in place in both the flying surface and the control surface. The hinge pivot points need to be exactly parallel to each other and precisely located on the center of the hinge line. The control surfaces of this model are predrilled for the hinges included in hardware package. Sand each end of the hinges using coarse sandpaper. This will improve the bond of the epoxy to the hinge. Carefully slide the remaining wing panel onto the other half of the wing pin. The fit may be tight; use caution when inserting the wing panels onto the wing pin. Make sure both wings fit well and there is no gap between them. Install the joint wings onto the fuselage with two pins in the leading edge sliding into the holes provided in the fuselage. Install the belly pan onto the fuselage. Secure the wing panels and belly pan using the provided wing screws. Mix some 30-minute epoxy. Using a glue syringe or toothpick, place a sufficient amount of the epoxy into one of the hinge pockets in the aileron leading edge. Install one of the hinge points until the hinge pin center is flush with the leading edge of the aileron. Wipe away any excess epoxy with rubbing alcohol. Continue installing hinges in the leading edge of the aileron. The control surfaces (ailerons) will be installed after the epoxy is fully cured. Note: Be sure that the hinge pivot pins are parallel and flush to the aileron leading edge. It s important to frequently mix a fresh batch of 30-minute epoxy in order to achieve good glue joint penetration. If you notice the epoxy becoming thicker, then mix a new batch! When the epoxy is cured, work each hinge throughout its full motion several times using your hands. This will break free any epoxy that may have found its way into the hinge joint. Move the hinge throughout its full travel until no resistance is felt. 16 5

8 Mix some 30-minute epoxy. Place a sufficient amount of epoxy in each of the hinge pockets in one wing panel. Carefully attach the aileron to the wing, making sure the hinges are inserted in their respective hinge pockets. Press the aileron and wing together until the hinge line gap between the aileron and wing is small enough. Use a paper towel and rubbing alcohol to wipe away any visible epoxy around the hinges. Section 9 Tail Hook Installation Fuselage Tail hook Mount the tail hook onto the provided brace with a screw and lock nut. Step 6 Double-check the hinge gap and allow the epoxy to fully cure for enough time. Now is a good time to repeat Steps 1 through 5 for the remaining wing panel and aileron. Step 7 When fully cured, move each control surface throughout its travel range several times to break away any epoxy in the hinge. Be sure to deflect the surface fully. Note: It s a good idea to seal the aileron and elevator hinge lines airtight with a piece of covering to prevent flutter after you finish hinges installation. Slide the tail hook with brace through the hatch opening in the tail of the fuselage. Mount the brace into the slot with epoxy. Section 3 Aileron Linkage Installation Control horn linkages (2) Adjust the linkage length until the holes in the ball links align with the outer hole in the servo arm and the second hole in the control horn when the aileron is neutral and the servo arm is centered. Attach the ball links to the outer hole in the servo arm and the second hole in the control horn with screws and nuts as shown. Repeat Steps 1 through 2 for the remaining servo in the opposite wing panel. Plug a servo extension onto the tail hook servo. Tie the servo leads together by using a secure connector, or a ribbon to prevent them from coming loose during flight. Secure the servo onto the hard wood servo mount with screws. Install the servo with mount into the slot with epoxy. Make a slot on the servo arm as shown. Attach the servo arm to the end of the tail hook. With the tail hook and the servo in their initial position, install the servo arm onto the servo using a screw. 6 15

Make sure to add a few pieces of foam between the fuselage and battery to prevent damage to the battery caused by vibration. Connect the battery to the ignition switch. Section 4 Flap Installation Wing panel (left and right) Flap (left and right) The technique for installing the flap is similar to the aileron installation. Please refer to Section 1, 2, 3 to install the flap. The control horn is pre-mounted in the flap. Install the flap servo with linkage, hinge the flap, attach the linkage to control horn and secure the flap servo cover with screws to complete the procedure. 1 Attach the fuel line from the fuel tank to the carburetor. Make sure the line is from the clunk and not the vent line. 2 Route the vent line from the fuel tank out of the bottom of the cowling. 3 Make any necessary cutouts to clear the engine components in the cowling. Remove a section from the bottom of the cowling near the exhaust pipe for cooling outlet as shown. This opening is necessary to allow cooling air to pass through the cowling to prevent overheating of your engine. 4 Install the cowling onto the fuselage using provided screws. Mount the propeller and spinner to complete the procedure. Section 5 Stabilizer Installation Stabilizer (left and right) Fuselage Stabilizer tube The opening for the elevator linkage is highlighted by a sticker on the fuselage. Carefully drill a hole for the opening at the highlighted position. 14 7

10 Install the elevator servo on the right position of servo tray in the fuselage. Attach the servo arm to the servo. Make sure the servo arm is perpendicular (90 ) to the centerline of the fuselage when the servo is at the neutral position. Install the linkage retainer onto the outer hole of the servo arm. The vertical and horizontal base lines are pre-marked on the firewall. Measure and mark the same distance from the lines for the four engine standoff screws. The firewall is already mounted correctly to provide right offset for the engine when the engine standoff center is on the intersection of the above lines. Locate the hard wood mounting position for the control horn on the elevator. Install the control horn to the position using the provided screws. Drill the holes in the firewall for mounting the engine. Install four screws from the back side of the firewall. You may apply epoxy glue here. Glue the elevator hinges in place using the same techniques used to hinge the ailerons. Install engine using four machined aluminum standoffs, screws and lock washers. Step 6 Install throttle servo with servo arm to the provided throttle servo mount. Drill a hole in the firewall for the throttle linkage to pass. Attach the linkage to the servo arm and throttle. Repeat Steps 1 through 4 for the remaining stabilizer and elevator. Step 6 Locate the stabilizer tube and carefully slide it into one stabilizer as deeply as possible. Slide the stabilizer (with tube) into the stabilizer tube opening in the fuselage. Make sure the stabilizer anti-rotation pin slide into the holes provided in the fuselage. Note: It may be necessary to slightly enlarge the hole in the fuselage for the anti-rotation pin using a small round file. Step 7 Install the exhaust pipe to the engine. Step 8 Secure the ignition module to the engine box. Make the connections between the ignition box and engine at this time. 8 13

11 Assemble the fuel tank correctly. Be sure to use the gas-compatible stopper and fuel tubing. Step 7 Carefully slide the remaining stabilizer onto the stabilizer tube that projects from the fuselage. Place foam on the floor of the tank compartment. Secure the tank in place by wrapping rubber bands or hook and loop straps around the tank and tank floor. Later we will run the fuel lines. Step 8 Make sure both stabilizers fit well with the fuselage and there is no gap between them. Secure the stabilizers with screws at the bottom as shown. Locate the hidden switch hatch on the side of the fuselage and open the hatch. Mount the receiver switch in the hatch and then close the hatch door. Step 9 Bend one end of the provided steel linkages. Assemble the provided wood rod with steel linkages on both sides. Section 8 Mounting the Engine and Cowling Fuselage Engine and accessories 0 Slide the heat-shrink tube in place where the wood rod with steel linkages connect to each other. Use a heat gun to heat the tube to fix the connection of the wood rod and steel linkages. 1 Attach the joined linkage to the linkage retainer on the elevator servo arm and the control horn when the elevator is neutral and the servo arm is centered. This model accepts gas engines ranging from 45 through 50cc. The following steps show the installation of a 45cc gas engine for your reference. The detailed steps may be different when your selected engine is different. R-45 Installation Collect the necessary items for the installation of your particular engine. 2 Repeat Steps 9 through 11 for the remaining elevator servo and control horn. 12 9

12 Section 6 Rudder Installation Rudder Fuselage The opening for the rudder cable is highlighted by a sticker on the fuselage. Carefully drill a hole for the opening on both sides of the fuselage. Install the rudder servo on the right position of servo tray in the fuselage. Attach the servo arm to the servo. Make sure the servo arm is perpendicular (90 ) to the centerline of the fuselage when the servo is at the neutral position. Step 6 Put the threaded rod of the rudder control horn through the hole and secure it with the provided nuts. Adjust the position of the rod so that it has the same length on both sides of the rudder. Screw the molded swivel link with linkage onto the threaded rod at the right position so that the rudder cable in operation will not hit the opening of the fuselage. Step 7 Hinge the rudder using the same techniques as with the aileron and elevator. Step 8 Put the rudder in its neutral position and center the rudder servo. Adjust the length of both rudder cables to match the distance from the rudder servo arm to the control horn. Use a plier to fix the length of the cables. Install the rudder cables on both sides of the outer holes of the rudder servo arm and control horn. Put the fuselage on its side with rudder virtually connecting. Using the provided rudder cable, measure a straight line from the rudder servo arm to the opening in, and mark the extension line on the rudder with a pen. Measure rearward 10mm (3/8 ) from the edge of the rudder bevel and make another mark using a pen. The intersection of the line from and this line will be the position for the rudder control horn. Section 7 Receiver, Battery and Fuel Tank Installation Fuselage Use foam and rubber bands (or hook and loop straps) to secure the receiver to the battery tray. Carefully drill through the rudder at the marked position, perpendicular (90 ) to the rudder centerline at the marked position. Be especially careful when penetrating through the backside of the rudder. Wrap the receiver battery in foam and use rubber bands or hook and loop straps to secure the battery to the battery tray
