Greetings and congratulations on your purchase of the Extreme Flight RC
52" Extra 300 EXP ARF!
This new Extra is the first in a series of midsized electrics built around the
new Xpwr T3910 brushless outrunner. This size aircraft delivers big plane
performance in a package that is easy to transport and maintain at a very
reasonable price point.
The 52" Extra is loaded with all of the groundbreaking tech first brought to
market in the 48" EXP models including generous use of carbon fiber and
fiberglass material to add strength while keeping overall weight very low. The
result is a very robust airframe capable of handling most aerodynamic loads
while remaining lightweight for best performance. The Extra excels in all
modern aerobatic flight regimes including low and slow 3D, fast and
aggressive XA and ultra precise precision flight.

Tips for Success:
1. Before starting assembly, take a few minutes to read the entire instruction
manual to familiarize yourself with the assembly process.
2. Please take a few minutes and go over all the seams on the aircraft with a
covering iron on a medium heat setting.
3. Use a fresh bottle of thin CA with a fine glue tip when attaching the CA
hinges. This will ensure that the proper amount of CA wicks into the hinge
and surrounding balsa wood and creates a proper bond between the wood and
hinges.
4. Apply a couple drops of CA to high stress areas such as anti-rotation pins,
landing gear mounts, servo trays and motor box joints .
5. When applying decals, first clean the area where the decal will be applied
with alcohol. Mist the area lightly with Windex before applying the decal
which will allow you to properly position it, then use a rubber squeegee to
push all of the liquid from under the decal. This will result in very few air
pockets trapped under the decal.
6. Take the time to properly balance and trim your aircraft and set up rates
and exponential values. Your flying experience will be greatly enhanced by
doing this.
Please note: The assembly of the 52" Extra is almost
identical to the assembly process of the previously
released EXP models. Some photos will show the
previous model component assembly steps.

Let's begin!
1. Locate the 2 wing panels with ailerons as well as the 2 G10 aileron control
horns and base plates. Remove the ailerons from the wing and remove the
covering over the slot for the aileron horn on the bottom of the aileron with a
sharp hobby blade. Make sure you are doing this on the bottom of the
aileron!
2. Scuff the portion of the control horn that will be glued into the aileron with
sandpaper.

3. Use a glue tip on your bottle of medium CA and apply glue to the slot as
well as to both sides of the control horn. Insert the control horn into the
baseplate and then into the slot and make sure it seats properly against the
surface of the aileron. Wipe away any excess glue with a soft cloth soaked in
Acetone.

4. Remove the covering from the aileron servo location and make sure the
hinges are centered in their slots.
5. Slide the aileron into position on the hinges and secure with several drops
of fresh thin CA. This process is much easier and more effective if a fine glue
tip is used. Make sure to deflect the surface as pictured while applying the
CA.

6. Use the screws provided by the servo manufacturer to secure the aileron
servo in the designated location. Make sure the output shaft is positioned
toward the leading edge of the wing.
7. Locate the 2 threaded aileron pushrods that are the same size and 4 micro
ball links along with 4 2mm screws, nuts and washers. Thread the ball links
onto each end of the pushrods and secure to the servo arm and control horn
with the 2 mm hardware as shown in the picture. We recommend the use of
the Extreme Flight lightweight electric servo arms as shown. Please note the
orientation of the pushrod in relation to the control horn.
Repeat this process for the other wing half.

8. Locate the carbon fiber main landing gear, 2 axles, 2 locking nuts, 2
wheels, 2 wheel collars and the 2 wheel pants from the hardware package.
Place the threaded portion of the axle through the hole in the carbon gear and
screw the lock nut onto the axle, but do not tighten completely. Place the
wheel onto the axle and secure with a wheel collar. There is a slot pre-cut in
the wheel pant to allow it to fit over the axle. Before installing the wheel pant
place a drop of silicon based glue onto the wheel pant just above the pre-cut
slot. This will prevent the wheel pant from rotating, but allow it to move in
the case of a mishap which may help to prevent damage. Slide the wheel pant
into position over the axle and tighten the nut on the axle, taking care to make
sure the wheel pant is positioned properly. Repeat this process for the
remaining wheel pant. Again this is probably better explained in the
following series of pictures.
