apply too much heat or you may cause bubbles or damage to the covering. A heat gun may also be used along with a soft cotton cloth to shrink and adhere the covering. Again, be extremely careful when using a heat gun. 2. Be sure to seal any exposed wood with a thin coating of epoxy to prevent engine oil from soaking in. This is especially important around the engine compartment and servo openings with exposed areas. 3. Some modelers prefer to seal the hinge gaps using strips of appropriate covering or clear trim tape. We have found this to be helpful with models intended for higher speed flight or models with unusually large hinge gaps. aircraft utilize a very tight double beveled hinge line and do not normally require this step. Sealing the hinge gaps is therefore left as an option for the modeler. ...

Screews & Washers for cowl: 4(3x14mm) Hexagon socket screws & 4 Washers RUDDER ASSEMBLY 1.It is much easier to install the twin control horns before installing the rudder. Locate the Carbon Fiber rudder control horns, ball links, and associated bolts and nylon‐insert lock nuts. Use some fine sandpaper to roughen up the center areas of the two control horns so that the glue adheres better. Using a sharp hobby knife or soldering iron remove the covering away from the slots in the rudder and trial fit the two control horns. 2. Mix up some 30 minute epoxy and coat the inside of the slots and the center of the control horns. Hint: a scrap piece of 1/16” ply, tooth pick, or old hobby blade can be used to coat the inside of the rudder slots. Slide the control horns in place and make sure they are centered perfectly by using a ruler to measure between the pivot holes and the hinge line. Wipe any excess glue off with isopropyl alcohol and paper towels. Install the ball links, bolts and nuts into the holes to help assure alignment of both control horns while the glue cures. ...
Page 26
3. Apply 30 minute epoxy to hinges, then insert them into the hinge slots on the rudder, secure the rudder with masking tapes, then allow the epoxy to dry. 4. The SU26M can use either closed loop or a rear push pull servo for the rudder. We recommend that you balance the model assembled before choosing your servo placement. A. The SU26M is supplied with a high quality set of pull‐pull cables and ball‐links. ...
Page 27
B. Install your rudder servo into the precut locations in the fuselage. Using a fine drill pre‐drill the holes and drop thin CA into the holes to strengthen the wood. You will need 3 inch arms on the servo. Set up your radio accordingly and center the rudder servo. C.Aluminum dual servo arm are include in the kit, enlarge the control holes with 2.5mm drill bit. D. The SU26M has the closed loop pre‐installed and crimped at the rudder end. These can be connected with the M2.5 screws and nuts. The wire will be left looped inside the fuselage and will need to be connected to the servo arm. ...
Page 28
E. Use your radio system to center the rudder servo and attach either the supplied arm or an appropriate arm for your servo. Thread one of the ball links about half way onto one of the threaded couplers. Feed the loose end of one of the cables through a brass tube and then through the threaded coupler. Holding the rudder centered, adjust the cable length as tight as possible while checking the ball link position over the servo arm. When satisfied with the position, pinch the cable around the threaded coupler and then feed the loose end back through the brass tube. Loop the cable back through the brass tube as before and crimp the ...
Page 29
F. Check the operation of the rudder using your radio and make sure there is no binding and the cables are adjusted properly. You may have to tighten the cables after a few flights as they may stretch slightly from the initial installation. 5.And SU26M also provide pull‐push style for rudder. Below is picture of pull‐push style linkage set . Cut off excess carbon fiber rudder horn, and use sandpaper to polish the parts needed to inlay, and use epoxy glue the carbon rudder horn. ...

LANDING GEAR ASSEMBLY 1. Locate the supplied main and tail wheel landing gear parts and sort them out on your workbench. 2. Bolt the main gear to the bottom of the fuselage using the supplied bolts. Place the bolts in through the can tunnel opening with appropriate size spanner. Remember the gear will rake forward. ...
Page 32
4. Install the main wheel axles to the composite landing gear and tighten the nylon‐insert lock nut. Install one wheel collar onto the axle. Use a second wheel collar as a guide to leave a gap on the inboard of the axle. Use a small drop of thread‐lock and tighten in place. Slide the wheel onto the axle and install a second wheel collar also using thread‐lock on the set screw. 5. Fit the wheel pant in place and install using the two supplied bolts. Use thread‐lock to secure the bolts in place. Repeat the above steps for the other main gear. ...

Page 39
4. Using plenty of 30 minute epoxy fit the horn and plate into place. Use a ball joint and bolt to hold the horn in place while drying. REPEAT FOR THE OTHER SIDE 5.Locate the horizontal stabilizer, use a hobby knife to remove the covering over the area that will be glued to fuselage, then glue it to the slot with 30 minute epoxy, allow to dry. ...
Page 40
6.Place long arms onto the servo’s you are planning to use for the elevators. 7.Fit the pushrod in place remembering one end is reverse threaded. Set it so the arm is centered and the elevator is flat. Choose the holes depending on how much deflection you require. ...
Page 41
8.There is an option to use one servo or two servos for the elevator. If using one servo, the 2 parts of the elevator need to be connected by the wood block with glue as shown below. The picture is for illustration only. Actually, the connection of the 2 parts needs to be performed in the fuselage after the hinges are connected. ENGINE(Motor), EXHAUST, & FUEL SYSTEM INSTALLATION ENGINE Installation 1. Select the proper guide for your engine and drill the holes and cut out the center as indicated. Notice that the engine center line is offset to the left to compensate for the right thrust built into the engine box. 2. Fit the Cowl and measure the distance from the engine bulkhead to the front of the cowl, add approx 2‐3mm for the back plate and this is the length that your engine should be set Using ...
Page 42
3. Mount the ignition module according to the manufacturer’s instructions. The best place to mount it is on the side of the engine box.

FINAL RADIO SYSTEM INSTALLATION 1. Whether you 72 MHz systems or the newer 2.4 GHz systems, proper radio installation and care is vital to the safe and reliable operation of your aircraft. Follow the manufacturer’s instruction for installation guidance of receivers and batteries paying attention to factors such as vibration isolation, adequate cooling, and clearances. 2. Mount your reciever(s) securely in a location which provides a clean and maintenance free solution to your setup. All servo wires should be neatly routed and secured in place so they will not come loose or flop around during flight. 3. The fuselage ply sides provide space to mount your switches just below the canopy. Mount your switches according to the manufacturer’s instructions and route your wires safely and securely as above. 4. Your receiver battery(s) can be mounted in a variety of locations depending on your balance ...
Page 48
Note: The best way to check your balance is to trim for level flight at about 1/2 to 3/4 throttle and then roll inverted. The aircraft should maintain level flight with very little to no down elevator input. If the aircraft climbs when inverted then you’ve probably got your CG too far aft. If the nose drops more than slightly, then you are most likely nose heavy. Recommended control surface deflections: Low Rate High Rate Elevator 15 degrees 45‐50 degrees Rudder 25 degrees 40 ‐ 45 degrees Ailerons 25 degrees 35‐40 degrees FINAL ASSEMBLY AND PRE‐FLIGHT INSPECTIONS 1. Before arriving at your flying field, be sure all your batteries are properly charged and all radio systems are in proper working order. 2. Install the wings onto the fuselage being careful to align the wing tube with the wings and not force it. The wing tube may be initially tight but will loosen some with use. Guide your servo wires into the fuselage openings and connect to the proper aileron channels. Servo clips are ...

4. Fill your fuel tank making sure your vent line is not plugged or capped. With the canopy off, this is a good time to check for any fuel leaks. 5. Position the canopy in place and tighten the canopy screws. Be sure to use the supplied rubber washers under the screw heads. 6. If you have removed your horizontal stabilizers, install them once again and check all bolts and connections. ...
