  • Page 19: Rudder Assembly

     Wrench set (Bag No. KA03CE) RUDDER ASSEMBLY NOTE: There are pictures of different planes in this manual, however, this plane’s wings is assembled the same way. 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.
  • Page 20 3．To fit the rudder to the fin, locate the rudder hinge wire and insert. To make it easier to insert twist as it is inserted.
  • Page 21 4. The CORVUS 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. 5. The CORVUS is supplied with a high quality set of pull-pull cables and ball-links. 6.
  • Page 22 8. 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.
  • Page 23 9. 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.

  • Page 24: Landing Gear Assembly

    LANDING GEAR ASSEMBLY 1. Locate the supplied main and tail wheel landing gear parts and sort them out on your workbench. 2. 2. Bolt the main gear to the bottom of the fuselage using the supplied screws and stainless steel Self- locking nuts.
  • Page 25 3. Place the Fairings onto the landing gear. 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.
  • Page 26 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. 6. Using silicone attaches the fairings to the fuselage. Use tape to hold them into position and leave for a few hours to ensure that the silicon has set.
  • Page 27 The installation is very simple, the factory has installed most of the accessories, please see the following pic ture. 8. Use your finger to find the three holes at the bottom of the fuselage. Using a knife clear the holes and fix the tailwheel in place.

  • Page 28: Wings Assembly

    WINGS ASSEMBLY NOTE: There are pictures of different planes in this manual, however, this plane’s wings is assembled the same way. 1. Aileron push rod linkage set. 2.5mmx60mm Pushrods for aileron. 2. Locate the slots for the aileron control horn and remove the covering with a sharp knife. Place the horns into position and the cover over the top to work out the area needing to be removed.
  • Page 29 3. Rough the area of the horn that will be glued in place. 4. Using 30 minute epoxy glue the horn and plate into the aileron. REPEAT FOR THE OTHER SIDE 5. Place the servo in the bay and drill holes for the servo screws. Remove the servo and apply thin cyano to the holes.

  • Page 30: Elevator Assembly

    6. We recommend using KUZA 1.5” aluminium CNC servo arm (sold separately) for wing control. Using the pushrods connect the servo arm to the horn. Remember that on the pushrod one end is reverse threaded. Use M2.5 screws and nuts to connect the pushrod. Set it so the aileron it level when the arm is at 90 degrees. REPEAT FOR THE OTHER SIDE ELEVATOR ASSEMBLY NOTE: There are pictures of different planes in this manual, however, this plane’s wings is assembled the same...
  • Page 31 2. Find the slots for the control arms in the elevators and remove the covering where the horns are inserted and the area for the plate. 3. Sand the area on the horn that will be glued inside the elevator. 4.
  • Page 32 REPEAT FOR THE OTHER SIDE 3． Use your radio to set the servo center position and install the large control horn onto the servo. Assemble the control rod and ball links and adjust the control linkage for proper geometry. When satisfied, screw the ball link to the servo arm and control horn.
  • Page 33 REPEAT FOR THE OTHER SIDE For 35CC version,Engine, Exhaust, & Fuel System Installation Engine Installation NOTE: There are pictures of different planes in this manual, however, this plane’s engine is assembled the same way. 1. Select the correct 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.
  • Page 34 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. Secure the pickup lead and ignition wires with zip ties so that they do not vibrate or touch any hot part of the engine or exhaust.
  • Page 35 5. Assemble the throttle servo mount using the supplied laser cut parts or there is a servo cutout in the bottom of the engine box for 28cc-38cc engines. Mount your throttle servo and complete your linkage setup. A hole will need to be drilled on the firewall to allow the pushrod to connect to the throttle arm on the carb. 6.

  • Page 40: Cowling Installation

    COWLING INSTALLATION 1.Test fit the cowl first, make sure it fits well with canopy and fuselage. 2. Drill 2mm holes on cowl and fuselage. 3.Enlarge the holes on cowl with 3mm drill bit. 4. Secure the cowl with 3x16mm Hexagon bolts and 10mm PTFE washers...
  • Page 41 To perform properly without being too pitch sensitive, you must not go too aft on the CG. GoldWing RC recommends an initial CG setting of 125-146mm(4.9-5.7 inches) behind the leading edge of the wing at the root. More experienced pilots may want to set the CG further aft for more 3D capability.
  • Page 42 engine, servo cutouts are provided in the rear of the fuselage for the rudder servos. These options should allow you to balance the model without adding any weight. 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.
  • Page 43 Then install pull-pull ball links on control horns. 3．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 after some with use. Guide your servo wires into the fuselage openings and connect to the correct aileron channels.
  • Page 44 Cut the wing film needed to be install the SFG. Fixed the SFG Use M3X18 hand bolts and balsa sheets. Installation of the SFG is optional. 5. 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.
