Note on Lithium Polymer Batteries
You will need a minimum 6-channel transmitter,
receiver and four servos. You can choose to purchase
a complete radio system. If you are using an
existing transmitter, just purchase the other required
equipment separately. We recommend the crystalfree, interference-free Spektrum™ DX6i 2.4GHz DSM®
6-channel system. If using your own transmitter, we
recommend the JR SPORT™ MN48 Mini servos.
If you own a Spektrum radio, just add a DSM2
and four JR SPORT MN48 mini servos. We show the
installation of the AR6200 receiver in the manual.

Lithium Polymer batteries are significantly
more volatile than alkaline or Ni-Cd/
Ni-MH batteries used in RC applications.
All manufacturer’s instructions and warnings
must be followed closely. Mishandling of
Li-Po batteries can result in fire. Always
follow the manufacturer’s instructions when
disposing of Lithium Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause
serious bodily harm and damage to property. Fly
only in open areas, preferably at AMA (Academy of
Model Aeronautics) approved flying sites, following all
instructions included with your radio.
Keep loose items that can get entangled in the
propeller away from the prop, including loose clothing,
or other objects such as pencils and screwdrivers.
Especially keep your hands away from the propeller.
During the course of building your model we suggest
that you use a soft base for the building surface.
Such things as a foam stand, large piece of bedding
foam or a thick bath towel will work well and help
protect the model from damage during assembly.
This is not shown in the assembly photographs to
display the detail of the actual building of the model.

1. Locate one of the wing panels. Separate the
aileron from the wing. Remove the hinges and set
them aside.
3. Use a pin vise and 1/16-inch (1.5mm) drill bit
to drill a hole in the center of each of the hinge
slots in the wing. Note that there are five (5) slots,
even though only three (3) hinges were removed in
the previous step.
4. Place a T-pin in the center of each of the hinges
as shown. You will need to prepare five (5) hinges
in this step. The additional hinges have been
supplied with your model.
5. Insert the hinges in the slots of the aileron.
The T-pins will keep the hinges centered so they
are positioned equally in the aileron and wing
when installed.
6. Position the aileron by sliding the hinges into the
slots in the wing.
2. Use a pin vise and 1/16-inch (1.5mm) drill bit
to drill a hole in the center of each of the hinge
slots in the aileron. Note that there are five (5)
slots, even though only three (3) hinges were

7. Check the alignment of the aileron. Use a ruler
to make sure the end of the aileron is aligned
evenly with the wing tip.
8. Remove the T-pins from the hinges. Set the hinge
gap using a hobby knife with a #11 blade. The
blade should just fit in the gap between the aileron
and wing.
11. Flex the aileron through its range of motion a
few times to break in the aileron hinges.
When hinging the aileron, do not use CA accelerator.
The CA must be allowed to penetrate the hinge or
the bond between the hinge and wood could fail.
9. Flex the aileron slightly so the hinges can be
seen. Make sure not to change the hinge gap in the
process. Saturate the hinges using thin CA on both
the top and bottom of the hinge to both sides of the
wing and aileron.
10. After the CA has fully cured, check to make
sure the hinges are secure by gently pulling on the
aileron and wing. If you find any loose hinges,
apply more CA to the hinge and recheck.
12. Repeat Steps 1 through 11 to join the
remaining aileron to its wing panel.
