Safety in Flying
This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme
maneuvers. It should only be operated by a competent pilot in a safe area with proper supervision.
ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to
fly.
NEVER fly over an unsafe area, such as a road or street.
Never fly too close to yourself or spectators.
Never run your motor inside a house or building with the propeller attached – Remove the prop for
safety.
Required Items
CA Glue – Thin and Thick
Epoxy glue
Hobby Knife
Small Phillips Screwdriver
Set Metric Allen Wrenches
Scissors
Small Pliers
Wire Cutters
Masking tape
Optional – Heat gun
Before Starting Assembly
Examination
Unpack your airplane and examine the components. Check for damage of any kind. If you see any
damage, please contact Value Hobby immediately.
Covering
Your airplane was packed in plastic at the factory without any wrinkles in the covering. You may notice
some wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane
out to the flying field. These wrinkles are the result of wood shrinkage and/or expansion. Balsa wood
changes size and shape slightly as it is exposed to varying humidity in the air. This is a natural property
of balsa wood. As your airplane adjusts to the weather in your part of the world, wrinkles may appear and
disappear. Wrinkles may be removed with the gentle application of heat to the covering material on your
airplane. The best tool to use is a hobby heat gun. Apply the heat gently: the covering material will shrink
as you apply the heat, and this will remove the wrinkles. BE CAREFUL! Too much heat applied too
quickly can damage the covering, either by causing it to pull away from the wood at seams and corners
or even by melting it. The covering will shrink at low temperature with patient application of heat.
Wrinkles in the covering DO NOT affect flight performance.
Remove the canopy before attempting to use heat on your covering! The canopy is made of
thermo-activated plastic and WILL deform with the application of heat. Do not apply heat to the canopy.
If you need to clean your airplane, we recommend using a damp towel. The paint used on the canopy
and cowl is not safe for all cleaners. In particular, DO NOT use alcohol on these parts, it will remove the
paint.

Section 4: Elevator Installation
Step 1. Test fit the horizontal stabilizer in the fuselage. It should be centered between the left
and right side. Using the wing tube as a guide, measure the distance from the tube to the
stabilizer as shown. Make sure this distance is also the same on the left and right sides.
http://www.valuehobby.com/
13
Step 2. Trace the outline where the horizontal stabilizer joins the fuselage using a marker.
Step 3. Using the outline from the last step, remove the covering over the horizontal stabilizer
that goes into the fuselage.
http://www.valuehobby.com/
14
Step 4. Insert in the elevator the four hinges into their appropriate slots and verify the correct
position and alignment of the elevator with the stabilizer. Then carefully glue the hinges, with
some drops of thin CA, in the elevator only.
http://www.valuehobby.com/
15
Step 5. Insert carefully the elevator through the fuselage.
Step 6.Insert carefully the stabiliser into fuselage space.
Locate the elevator hinges into the
stabiliser.
http://www.valuehobby.com/
16
Step 7. Flex the elevators 45 degrees up and down, make sure the elevator can move freely.
Then glue the hinges with thin CA.
Step 8. Slide the carbon fiber wing tube into the fuselage, and carefully check the alignment of
the stabilizer with the fuselage.

included in your kit. Make sure the motor spins freely . Depending on the size of the shaf t collar
on your motor, you may need to remove a small amount of wood from the firewall for free
rotation.

Section 10: Cowling Installation
Step 1. To mount the cowl, first locate the 4 small plywood rectangles on the inside of the
fuselage sides at the front of the fuselage. The cowl-mounting screws are screwed into these
plywood pieces. In order to know where these plywood rectangles are after we install the cowl,
tape small pieces of paper over the plywood rectangles as shown.
Step 2.
Install the cowl and align carefully so that the spinner matches the cowl a s desired. B e
sure canopy hatch is in place for this step.

Step 3. Use a hobby knife to make small holes through the paper strips into the cowling. This
locates the cowl screws accurately so that they will screw into the plywood. Use the 4 small
remaining wood screws to mount the cowl.
