ASSEMBLY:
1. Vertical and Horizontal Tail Surfaces
1. Flex all control surfaces (Elevator and rudder) to loosen the hinge joint.
2. Attach the horizontal stabilizer, and then insert the vertical stabilizer. Slot the front in first then
push home the rear of the vertical stabilizer, make sure this is a secure firm fit. Use two 2mm x
45mm self-tapping screws to mount the tail surfaces to the rear of the fuselage.
3. If you have no need to remove these parts or if you are going to push the BushMule to its
extreme flight envelope, the Avios team suggests that you apply either foam safe contact
adhesive or a long set time 2-part epoxy on these tail surfaces.
4. Use a Servo tester to center your elevator and rudder servos, then adjust the clevises until you
have a level and zeroed control service. (Hint: Placing some fuel tube or a small zip tie over
the clevis will stop it opening, very good for security and peace of mind.)
2. Landing Gear
1. Insert the landing gear leg into the front mounting bracket. Centre the nose wheel and tighten
the 1.5mm grub screw. (Use a thread lock and make sure the grub screw tightens onto the flat
part of the shaft). The V2 has upgraded servo connection components.
2. Centre the nose wheel steering servo with a servo tester and attach the control rod from the
servo arm to the connecting arm of the nose gear shaft.
3. Attach the main landing gear (re-positioned on the V2), simply insert the pre-bent wire of the
landing gear into the slot in the center of the fuselage. Use the two mounting brackets and the
four 2mm x 13mm self-tapping screws to secure the main gear.
5

3. Installation of main wing
1. The main wing center piece houses the motors, ESC’s, flaps, flap servos and main wiring
harness.
2. Please center all servos, and flex the ailerons on the outer wing panels.
3. Connect all control rods to the control horns with the supplied hardware to the flaps and ailerons.
4. Label the wiring harness and bundle them together to keep the wiring harness from getting
caught between the main center wing and fuselage.
5. Use the two M4 x 55mm main wing machine screws to secure the main center wing section to
the fuselage (with the V2 these will be screwing into brass threads).
6. Slide the two square machined aluminum wing spars into the main wing section, attach the servo
extension leads to power your lights and ailerons.
7. Once the outer wing panels are fully home on the center section, use the four 2mm x 15mm
selftapping screws to fasten the outer wing sections to the main center wing section.
8. Attach the wing strut support with the 4 supplied split pins. Please check the wing at this point to
make sure the dihedral angle is the same for both outer wing sections.

4. Electronic avionics set up
1. The BushMule V2 ideally uses a 6 channel receiver as a minimum to get the best from the
model. Bind your chosen receiver to your transmitter, and plug in all the servos to the corre-
sponding channels.
2. These controls consists of the Throttle, Ailerons, Elevator, Rudder, Flaps and Cargo Door.
3. Plug your 4S LiPo flight battery into the XT-60 battery connector that powers up your BushMule
V2.
4. Check the rotation of the out-runner motors, they should both spin in opposite directions, and
both should rotate inwards towards the fuselage.
5. Check all your control services and make sure they are all operating the correct way without any
binding issues. Adjust mechanically the length of the servo push-rods to center all the control
surfaces.
5. Control Set-up
1. The Avios BushMule V2 handles extremely well, is very maneuverable through all ranges of the
flight envelope. In saying this, your Avios BushMule V2 needs setting up before your initial maiden
flight. After the first flight, then you can adjust the control surfaces to suit your own preferences.

6. Centre of Gravity
The centre of gravity or CoG is the most important measurement for a successful maiden flight of
any model airplane.
The suggested CoG for the Avios BushMule V2 is 50-60mm from the leading edge of the wing
with your flight battery installed. We suggest aiming for the 50mm forward position for initial flights.
CG LOCATION:
11
CG 50-60 mm ~ from
leading edge.
With assembly and set-up now complete, your Avios BushMule V2 should
be ready for flight. However we recommend you read and follow the
advice given in the next stage of this manual before flying your model.

12
7. Hints
We have a few hints to help when flying the Avios BushMule V2, when measuring the CoG take
some time to adjust this to match your flying style. Moving the battery to adjust the CoG forward
and aft to find your personal balance point. Once again we suggest keeping in near the forward
mark for initial flights.
Another great tip is to balance your new plane laterally (wing tip to wing tip) this is sometimes
looked over, but is an important step before you fly.
Balancing the 3 bladed propellers helps to keep vibration to a minimum, and helps with efficiency of
the drive train. With your Avios BushMule V2 fully built and ready for flight now is a perfect time to
go over your model once more to make sure nothing has been overlooked, check that all screws,
nuts and bolts are secure, and that your flight control surfaces are set correctly and secure.
8. Optional Skis
Your BushMule V2 comes supplied with high quality plastic skis for use on snow and even on
sand. These skis add greatly to the versatility of the BushMule V2, and are very straight forward to
install. They add a fun and exciting aspect to flying the model, please follow the guide below when
installing the skis.
With all wheels removed from the undercarriage slide each ski onto the wheel axles followed by
the tension spring. Ensure the loop at the rear of the spring is correctly located onto the plastic
post as shown. With the spring located and installed, secure each ski to the axle with the wheel
collars. Note, when not on the ground all skis should spring forward/upwards, this is normal.

9. Model Flying Precautions
1. Select your flying area carefully. Always choose an open space that is unobstructed from trees
and buildings and away from crowded areas. Avoid flying in areas with roads, electric or telephone
poles and wires, and water, nearby or within close proximity to full size controlled airspace.
2. Do not fly this model in poor weather. This includes high winds, low visibility, inclement weather,
rain and storms are to be avoided.
3. Never attempt to catch the model whilst in flight, even a slow-moving model can cause harm to
yourself and/others, and risks damage to the model.
4. This model is recommended for children no younger than 14 years old. All children, no matter
what age, should always be supervised by a capable and responsible adult when operating this
model.
Always unplug your models flight battery when not in use, never leave the battery installed in your
model. Please remember to keep clear of the propellers at all times when your flight battery is
connected. Before flying, always turn on your transmitter first then plug your flight battery into your
model. After flying, always unplug your flight battery first then turn off your radio transmitter.
Exercise caution when charging your batteries and follow in full your battery manufacturers safety
guidelines when doing so.
10. Pre-flight Checks:
• Always perform a range check between your Transmitter (TX) and Receiver (RX). Please follow
your Transmitter manufacturers guidelines for performing this important check.
• Check all screws, nuts, bolts, grub screws and ensure all mounting points are firmly secured,
including control horns and clevises.
• Only fly with fully charged batteries (both flight batteries and transmitter batteries) Failure to do so
could result in loss of control, and possible damage to persons and property. Always check your
batteries and have a system that works for you with flat and fully charged batteries.
• With your BushMule V2 powered up check all your control surfaces are free from damage/
obstructions and moving in the correct directions.
• Always inspect the model and propellers for any damage that may have occurred during transit
and listen for any unusual sounds from the electronics when powering up. If in any doubt about
any aspect of your model then do not fly it.
• With your model held securely, and the propellers free from obstructions, increase the throttle to
confirm the rotation is in the correct direction.
• If this is the first flight with your BushMule V2, double check the CoG is at the correct position. If
not adjust the battery position inside the battery area to achieve the required balance point.
• If you are an inexperienced RC pilot then please seek the help and assistance of an experienced
RC pilot, to help and confirm these final checks, and to test fly the model for you.

11. Flying The Bushmule:
• Your Avios BushMule V2 is one of the most versatile, stable and predictable RC airplanes to fly. It
is a fantastic introduction to the world of twin motored RC flying.
• When flying, the counter rotating propellers will give the model zero, or limited torque effect as the
motors are spinning in opposite directions.
• The BushMule V2 has a very wide flight envelope, and will happily fly very slowly with the help of
the large barn door style flaps, the BushMule V2 is a true STOL (Short Take Off and Landing)
workhorse. But, when you open the throttle, the power is perfectly distributed from the 4S flight
battery to the twin 30A ESC’s and the powerful, and reliable brushless outrunner motors. Spinning
two 10 inch propellers the power is converted to a stampeding barnstorming utility thoroughbred.
No horsing around, the Avios BushMule V2 is a great flying RC platform.
• Changing the large “Tundra” like wheels to skies or optional floats make this RC airplane a special
and unique kind of animal.
• With your additional FPV (First Person View) equipment, the BushMule V2 converts easily to a
FPV superstar. Pan and tilt cameras, flight cameras, and VTX’s will easily fit in the well thought out
positions, and huge fuselage spaces.
12. From Avios to the customer:
• Firstly, thank you for purchasing the Avios BushMule V2 and welcome to the adventure of all
terrain flight, "Anytime, Anywhere".
• Whilst not essential to flying, the use of coordinated rudder in flight will add to the general handling
through to slow speed manoeuvres, will improve your flying skills and let you explore the full
potential of this fine model. A mix of 40% aileron-rudder is recommended as a good starting point.
From there you can adjust this mix to suit your flying style.
• Although it can be, the BushMule V2 doesn’t need to be flown at full throttle all the time. Dropping
back on the throttle will not only let you enjoy it at a more relaxed pace, but will also result in
longer flight times, reduce the risk of the motors and ESC’s over heating in hot weather, and will
increase the life of your flight pack.
• Flight packs of 20C discharge rate or above are recommended to ensure optimal performance in
flight.
• Keep all leads within the fuselage area as tidy as possible. Tidy wires not only look better but also
allow for easier access to all internal components, increase airflow around electronics, and reduce
the risk of electronic interference.
• Inspect the propellers, and mounting nut/bolts frequently, especially if you’ve suffered a hard
landing or a prop has been knocked.

• Inspect the propellers, and mounting nut/bolts frequently, especially if you’ve suffered a hard
landing or a prop has been knocked.
• If you intend to use the supplied skis on snow, and sand, or you wish to fit the optional floats, and
fly off of water, it is recommended that you add a coat of clear acrylic varnish to the applied decals.
Prolonged exposure to water may cause the decals to lift from the surface, leaving a tired appear-
ance, let’s face it, no one likes a tired looking ass. Please, test your varnish on a scrap piece of
EPO first to ensure it does not react to the foam.
• Our final suggestion is to add a mixture on your Transmitter to enable throttle to be mixed with
your rudder inputs. Even though the optional floats have the provision for a water rudder it’s a lot
easier to taxi on water, snow or rough fields with this additional mix. Flying the BushMule V2 with
this throttle / rudder mix also opens up the Bushmule’s wild side with flat spins and crazy antics.
(please check your transmitters owner’s manual for the mixing instructions.)
