ASSEMBLY
1. Vertical and Horizontal Tail Surfaces
• Flex all control surfaces (Elevator and rudder) to loosen the hinge joint.
• Attach the Horizontal tailplane and then insert the vertical stabilizer with the front first then home the
rear of the vertical stabilizer. Make sure this is a secure firm fit. Use 2 2mm x 45mm self-tapping
screws to mount the tail surfaces to the rear of the fuselage.
• The Avios team suggests that you apply either foam safe contact adhesive or a long set time 2-part
epoxy on these tail surfaces. If you have no need to remove these parts or if you are going to push
the Bushmule to its extreme flight envelope.
• Use a Servo tester to centre your elevator and rudder servos, then adjust the clevises until you
have a level and zeroed control service. (Hint-Placing some fuel tube or small zip tie the secure the
clevis is always a good for security and peace of mind.)
2. Landing Gear
• Insert from landing gear leg in 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)
• 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.
• Attach the main landing gear, simply insert the pre-bent wire of the landing gear into the slot in the
centre of the fuselage. Use the two mounting brackets and the four 2mm x 13mm self-tapping
screws to secure the main gear.
3. Installation of main wing
•
•
•
•

•
•
•
The main wing centre piece houses the motors, ESC’s, flaps, flap servos and main wiring harness.
Please centre all servos, flex the ailerons on the outer wing panels.
Connect all control rods to the cont rol horns with the supplied hardware to the flaps and Ailerons.
Make the wiring harness is labelled and organised then bundled together to keep the wiring harness
from getting caught between the main centre wing and fuselage.
Use the two M4 x 55mm main wing machine screws to secure the main centre wing section to the
fuselage.
Use the two square machined aluminium wing spares and slide them into the main wing section,
attach the servo extensions to power your lights and ailerons.
After you home the outer wing to the centre main wing section use the four 2mm x 15mm self-tapping screws to fasten the outer wing sections to the main centre wing section.
Attach the wing strut support with the 4 available split pins. Please check the wing at this point to
make sure the dihedral angle is even with both outer wing sections.

4. Electronic avionics set up
• Requiring a minimum 6 channel receiver bound to your transmitter plug in all the corresponding
channels.
• These controls include the Throttle, Ailerons, Elevator, Rudder, Flaps and cargo door.
• Plug your 4S LiPo flight battery into the XT-60 battery connector that powers up your Bushmule.
• Check the rotation of the outrunner motors, they should both spin in opposite direction. Either both
towards the fuselage or towards the wing tips.
• Check all your control services and make sure they are all operating the correct way without any
binding issues. Adjust mechanically if they are not equally centered.
5. Control Set-up
• The Avios Bushmule handles extremely well, is very manoeuvrable through all ranges of the flight
envelope. In saying this your Avios Bushmule needs setting up before your initial maiden flight.
After the first flight the you can adjust the control surfaces to suite your own preference.

Basic assembly of your Bushmule is complete.
Now perform a final check on all screws, bolts and components,
ensuring all are secure and firmly in place.

6. Centre of Gravity
The centre of gravity or CoG is the most important measurement for a successful and comfortable
flight.
The suggested CoG for the Avios Bushmule is 50-60mm from the leading edge of the wing.With your
flight battery installed balance the Bushmule will fly perfectly at the required measurement.
CG Location:
CG 50-60 mm ~ from
leading edge.
With assembly and set-up now complete, your Avios Bushmule 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.
7. Hints
We have a few hints to help when flying the Avios Bushmule, 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.
Another great tip is to balance your new plane laterally (wing tip to wing tip) this is a looked over but
important balance before you fly.
Balancing the 3 bladed propellers always helps to keep vibration to a minimum and help with efficiency.
With your Avios Bushmule fully built and ready for flight now is a perfect time to go over your model
once more to make sure nothing is over looked, all screws, nuts and bolts are secure and your flight
control surfaces are all correct and secure.
8. OPTIONAL SKIS
Your Bushmule 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 and are very straight forward to install and 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 ensuring the loop at the rear of the spring is corrected located onto the plastic post as
shown. With the spring location and installed in place, secure each ski to the axle the wheel collars.
Note, when not on the ground all skis should spring forward/upwards. This is normal.

9. MODEL FLYING PRECAUTIONS
• Select your flight area carefully. Always choose an open space that is unobstructed from trees and
buildings and away from crowed areas. Avoid flying in areas with roads, electric/telephone
poles/wires and water nearby or within close proximity to full size controlled airspace.
• Do not fly this model in poor weather. High winds, low visibility, inclement weather, rain and storms
are to be avoided.
• Never attempt to catch this model whilst in flight. Even a slow-moving model can cause harm to
yourself and/others and risks damage to the model.
• 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 model 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
guideline 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 screw, nuts, bolts, grub screws and 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, 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 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 your Bushmule. If any doubt
do not fly the model.
• 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 maiden or first flight with your Bushmule 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 flyer then please seek the help and assistance of an experienced
RC pilot to help and confirm these final checks and test fly the model for you.
11. FLYING THE BUSHMULE:
• Your Avios Bushmule is one of the most versatile, stable and predictable RC aircraft to fly. A fantastic introduction to the world of twin motored RC flying.
• When flying the Bushmule the counter rotating propeller will give the flyer zero or limited torque
effect as the motors are spinning in opposite directions.
• The Bushmule has a very wide flight envelope happily flying slow with the large barn door style
flaps, the Bushmule is a true STOL (Short Take Off and Landing) workhorse. But, when you put the
throttle down the power is perfectly distributed from the 4S flight battery to the twin 30A ESC’s to 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 is a great flying RC platform.
• Changing the large “Tundra” like wheels to skies or optional floats make this RC aeroplane a
special and unique animal.
• With your additional FPV (First Person View) equipment the Bushmule converts easily to a FPV
superstar. Pan and tilt cameras, flight camera 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 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, 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 suite your flying style.
• Although it can be, the Bushmule doesn’t need to be flown at full throttle all the time. Dropping back
on the throttle will not only let you enjoy the Bushmule 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
increase the life of your flight pack.
• Flight packs of 20C discharge rate or above are recommended for use in the Bushmule 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 the prop has been knocked.
• If you intend to use the supplied skis on snow and sand or wish you wish to fit the optional floats
and fly off 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 and have tired
appearance, 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 badly.
• 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 with this throttle /
rudder mix also opens the Bushmule’s wild side with flat spins and crazy antics. (please check your
transmitters owner’s manual for the mixing instructions.)
Thank you again for purchasing the Avios Bushmule.
We hope you’ll have many happy days of flying in wide open skies
Don't forget, spare parts are available for this model,
