aircraft designs available and include many innovative construction techniques. We’ve taken this
expertise and teamed up with EG Aircra ft to bring this new model to the radio control enth usiasts. The
Corvus is designed for the popular 50-70 cc engines and weighs about 16.5 lbs to 18 lbs. Perfect for
IMAC or Freestyle, this new EG giant offers everything you want in a giant scale aerobat i nc l u din g great

AN IMPORTANT MESSAGE ABOUT SAFETY AND RADIO CONTROL FLYING

MODELS

Flying radio control aircraft, like any hobby or sport, contains certain risks. The operator of these
models is responsible for these risks. If the airplane is misused or abused, you may cause serious bodily
injury and/or damage to property. With this in mind, you will want to be certain that you build your
model carefully and correctly. If you are not an experienced flier, have your work checked and ask for
help in learning to fly safely . This model aircraft is not a toy and must be operated and flown in a safe
manner at all times. Always perform a pre-flight check of the model including all control surfaces, proper
function of the radio gear, structure, radio range, and any other area relating to the safe operation of this
aircraft.

Models are not insurable but operators are. You can obtain coverage through membership in the
Academy of Model Aeronautics (AMA). For an AMA information package call 1-800-435-9262, ext.
292 or visit the AMA website at "www.modelaircraft.org

Note: As with all kits, to correctly understand the construction of your airplane it is
important that you read all the instructions and study the parts before you begin
construction. Handle the parts of this kit with care so you do not damage any of the
structure or covering. 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.

AIRCRAFT COVERING:

1. With all ARFs, varying temperatures and storage delays can cause covering material to loosen over

time and transportation. EG recommends lightly going over all the covering with a covering iron set
at medium temperatures. Be sure to use a soft cover over your iron so you d o not sc ratch the covering
surface. Be sure you go over all seams and edges of the covering to assure it is secure to the airframe
and other covering. Be careful not to apply too much heat or you may cause bubbles or damage to the
covering. A heat gun may also be used alon g 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. EG 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.

RUDDER INSTALLATION:

1. It is much easier to install the twin control horns before installing the rudde r. Loca te the Ca rbon 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.

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. Set aside until cured. NOTE: There are pictures of different planes
in this manual, however, this plane’s rudder is assembled the same way.

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 o peration. The hinges should seat fully into the slots so that the hinge
line gap is minimal while still allowing full rudder deflection.

4. Before gluing the hinges in you must first c lean the hinges of any mold release agent usin g isopropyl

alcohol, and scuff up the plastic with light sandpaper for maximum glue adhesion.

5. Mix up some 30 minute epoxy and using a toothpick or small wooden dowel coat the inside of each

hinge slot with epoxy. Also put a thin layer of epoxy on one end of the flat hinges. Install this end
into the slots of the rudder and make sure each hinge is properly aligned at exactly 90 degrees to the
hinge line.

6. Now coat the other end of the flat hinges with epoxy and install the rudder into the trailing edge of the

vertical stabilizer. Again, make sure the hinges remain in proper alignment. Using paper towels and
some isopropyl alcohol clean off any excess ep oxy from the hinges and surrounding areas.

7. Make sure the rudder is fully seated so that the hinge gap is minimal while still allowing full deflection

of the rudder. When satisfied, use some masking tape to hold the rudder in pl ace along the bottom and
counterbalance. After the epoxy has cured, remove the masking tape and check for proper operation.
If the hinges are dry some light oil carefully placed on each hinge will help greatly.

LANDING GEAR ASSEMBLY:

1. Locate the supplied main and tail wheel la nding 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.
