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. Avoid using a heat gun on seams.
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. We are big fans of the Mercury line of adhesives as well as the glue
tips provided by them.
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 and carbon support
mounts.
5. All of the G10 control horns are the same with the exception of the elevator
horn. Its base has been shortened to fit the depth of the elevator.
6. 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.
7. 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 process for the MXS is pretty much identical
to that of the Extra and Edge EXP. Many of the photos in this manual will
show the Extra airframe. Only those assembly steps which differ will show
the MXS (mainly the installation of the dual ball link pushrod assemblies and
the installation of the elevator and horizontal stabilizer).

Items needed for completion
-masking tape
-Thin and medium CA. We highly recommend Mercury M5T thin and M100XF medium
formulas as well as the Mercury glue tips.
-30 minute epoxy. The new Mercury adhesives Epoxies have worked very well for us.
-Blue Loctite.
-Silicon based glue (Zap-A-Dap-A-Goo, etc.)
-Electric drill with an assortment of small drill bits.
-Small flat head and Phillips head screw drivers.
-Standard and needle nose pliers.
-Metric balldriver or allen key set.
-3 sub micro metal geared servos and 1 micro metal geared servo. All flight testing was
performed with Hitec HS-65MG and HS-5065MG digital servos on the ailerons and rudder
and a single Hitec HS-85MG on the elevator. We strongly recommend the use of these high
quality servos.
-Torque 2814T/820 Brushless Outrunner motor. This is the motor that this aircraft was
designed around and will deliver the best performance for the MXS.
-Airboss Elite 45 Amp ESC.
-4S 2350-3000 mah LiPo battery. We've had great success with the Thunder Power line of
batteries as well as the Zippy Rhino and Flightmax bargain LiPos available from
www.hobbycity.com in both 2350 mah and 2650 mah sizes.
-APC 12x6 E prop (NOT the slow fly version!).
-52mm Extreme Flight spinner.
-2 18"-24" extensions for the 2 rear servos and 2 6"-8" extensions to go between the
receiver and the aileron servo leads. We recommend the 28 or 32 AWG extensions to save
weight.
-Adhesive backed Velcro and Velcro strap for battery retention.

Let's begin!
1. Locate the 2 wing panels with ailerons as well as the 2 G10 aileron control
horns. 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 slot
and make sure it seats properly against the surface of the aileron.
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. 1 screw installed in the center hole at each
end of the servo is adequate to secure the servo. Make sure the output shaft is
positioned toward the trailing edge of the wing.
7. Locate the 2 threaded pushrods that are the same length 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. Use the longest arm provided
with your servo.
Repeat this process for the other wing half.

8. Locate the fuselage, one piece carbon fiber landing gear (the gear pictured
in the photo is the curved Extra landing gear. The gear legs on the MXS are
straight), 2 silver 3mm machine screws and 2 washers. Secure the landing
gear to the fuselage by inserting a 3mm screw into a washer, through the
carbon fiber gear and into the pre-installed blind nut in the fuselage. Make
sure to use a drop of blue Loctite on each screw to prevent them from backing
out.
9. Locate the 2 axles, 2 locking nuts, 2 wheels, 2 wheel collars and 2 wheel
pants from the hardware package. Place the wheel onto the axle and secure
with a wheel collar. 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. 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.

10. Locate the horizontal stabilizer/elevator assembly and slide the elevator
off of the hinges. Please pay careful attention here!!! You must insert the one
piece elevator into the fuselage before installing the horizontal stabilizer! The
elevator must be inserted into the fuselage upside down with the counter
balances facing the rear of the aircraft as shown in the following photo. Once
inserted into the fuselage the elevator can be rotated 180 degrees and placed
in the proper location.
