  • Page 2 Dear EG Customer, Thank you for purchasing the new EG 60CC Corvus 540. EG is known worldwide for the best aerobatic aircraft designs available and include many innovative construction techniques. We’ve taken this expertise and teamed up with EG Aircraft to bring this new model to the radio control enthusiasts. The Corvus is designed for the popular 50-70 cc engines and weighs about 16.5 lbs to 18 lbs.
  • Page 3 EG WARRANTY AND RETURN POLICY EG guarantees this product to be free from defects in both material and workmanship at the date of purchase. This does not cover any parts damaged by use, misuse or modification. In no case shall EG's liability exceed the original cost of this kit.

  • Page 4: Included Features

    Included Features: • • Covered in Genuine Ultracote / Carbon fiber tail wheel assembly with Oracover CNC machined metal parts, including • Complete and Detailed Instructions the aluminum tail wheel hub on CD • Carbon reinforced fuselage and • Fits new DA60 and 3W55 Engines wings.
  • Page 7 Inspect all the parts for any shipping damage and report any issues to EG as soon as you can. Make sure you have a flat and sturdy workbench and follow all safety rules for the tools and adhesives you plan to use.

  • Page 8: Rudder Installation

    RUDDER INSTALLATION: 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 cut the covering away from the slots in the rudder and trial fit the two control horns.
  • Page 9 3. The slots for the supplied flat hinges are pre cut. Locate the flat hinges and dry fit the hinges and rudder into place and test the operation. The hinges should seat fully into the slots so that the hinge line gap is minimal while still allowing full rudder deflection.

  • Page 10: Landing Gear Assembly

    LANDING GEAR ASSEMBLY: 1. Locate the supplied main and tail wheel landing gear parts and sort them out on your workbench. NOTE: There are pictures of other planes in this manual, however, the Corvus is assembled the same way.
  • Page 11 2. Bolt the main gear to the bottom of the fuselage using the supplied bolts. Use a small drop of thread- lock to secure the bolts in place.
  • Page 13 3. Bolt the gear cover plate in place using the single bolt provided and the hole in the center of the 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.
  • Page 14 5. Fit the wheel pant in place and install using the two supplied screws. Use thread-lock to secure the screws in place. Repeat the above steps for the other main gear.
  • Page 15 6. Tail wheel assembly with CNC machined metal parts, including the aluminum tail wheel hub The installation is very simple, the factory has installed most of the accessories, please see the followin g picture.
  • Page 16 Find the carbon plate screw mounting holes on the fuselage, use a knife to open the Oracover, then use three screws to attach the carbon plate to the fuselage using thread- lock. Then install the spring, using the self-tapping screws to attach the other end of the spring onto the rudder.
  • Page 17 8. The following is a picture of properly installed tail wheel assembly. RUDDER CONTROL INSTALLATION: 1. The Corvus is supplied with a high quality set of pull-pull cables and ball-links. NOTE: There are pictures of other planes in this manual, however, the Corvus is assembled the same way. 2.
  • Page 18 5. Thread the couplers about half way into the ball links of the rudder. Hint: remove the ball links from the rudder horn first to make this step easier and then re-install once the couplers are threaded on. Feed the loose end of each cable into the cable slots at the rear of the fuselage and feed them forward towards the servo mount location.
  • Page 19 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 brass tube three times just tight enough not to cut the brass tube but enough to securely hold the wire in place.
  • Page 20 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 the correct length stand offs, mount your engine securely using bolts, washers, and locknuts.
  • Page 21 6. An extra servo can be fitted for choke or a mechanical linkage can be used. 7. The fuel tank is preassembled. Complete the installation in the fuselage using zip ties or velcro straps to hold the tank in position. Connect a fuel line between the tank and carb, a fuel line between the tank vent and the bottom of the fuselage, and a fill line to a fueling port which can be mounted on the fuselage side opposite your ignition switch.
  • Page 22 A barb on the bottom of the fuselage can be fitted for the vent. 8. The CORVUS comes with canister pipe tunnel. Standard muffler, pitts muffler, canister or tuned pipe can be fitted. If a tuned pipe is going to be used the end of the can tunnel can be removed. The tunnel can be closed off to accept canisters of all sizes, or stock mufflers.
  • Page 23 Tuned Pipe Mounting The Corvus comes with many openings for the exhaust outlet, line up the exhaust then remove the covering for the required outlet. They come with covers that can be used for cooling. Use a soldering iron to open up the holes.

  • Page 24: Cowling Installation

    COWLING INSTALLATION: 1. With the engine fitted, tape a piece of card to the bottom of the fuselage that can overlap the cylinder head. Remove the engine and refit the cowl. Then fold over the card to show where the cylinder head would be as below.
  • Page 25 Again, EG recommends you temporarily install the ball link onto the horns while the glue cures. This will assure proper alignment of each horn. NOTE: Pictures of different planes are shown in...
  • Page 26 2. Install your elevator servo into the root of the horizontal stabilizer making sure the servo wire exits towards the leading edge of the stab. 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.
  • Page 28 4. To install the horizontal stabilizers you first need to install two 42” servo wire extensions in the fuselage so that they extend from the radio compartment to the aft openings. A servo wire tunnel is provided in the fuselage to guide the wires. 5.
  • Page 29 If you are new to “ganged servo” setups, EG recommends you seek assistance from a local experienced modeler or have them double check your work.
  • Page 30 progress to assure a zero-binding operation. Once satisfied, permanently attach the ball link to the servo arm with the supplied screw and nut.
  • Page 31 7. Check the final radio operation of the ailerons and make sure there is no binding or servo fighting of each other. Also check to make sure all linkage bolts and nuts are secure. FINAL RADIO SYSTEM INSTALLATION: 1. Whether you 72 MHz systems or the newer 2.4 GHz systems, proper radio installation and care is vital for the safe and reliable operation of your aircraft.
  • Page 32 To perform properly without being too pitch sensitive, the CG should not be to far aft. EG recommends an initial CG setting of 5.0 – 6.0 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 33 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.
