Battery installation
Receiver diagram
Preight check
Important ESC and model information
1. Remove the battery hatch.
2. Remove the hook and loop tape from the
fuselage. Apply the looped surface to the battery.
3. Install the battery into the fuselage- securing it
with the preinstalled battery straps.
Note: The weight of each battery may vary due
to different manufacturing techniques. Move the
battery fore or aft to achieve the optimal center of
gravity.
1. The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick
is not in the low throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off
position. Once the throttle stick is moved to the low throttle or off position, the motor will emit a series of beeps. Several
beeps with the same tune means the ESC has detected the cells of the battery. The count of the beeps equals the cells of
the battery. The motor is now armed and will start when the throttle is moved.
2. The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the motor is
rotating in the wrong direction, simply reverse two of the three motor wires to change the direction of rotation.
3. The motor has an optional brake setting. The ESC comes with brake switched off and we recommend that the model
be own with the brake off. However, the brake could be accidentally switched on if the motor battery is connected to
the ESC while the throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full throttle and
plug in the motor battery. The motor will beep one time. Move the throttle stick to low throttle or the off position. The
motor is ready to run and the brake will be switched off.
4. Battery Selection and Installation. We recommend the 2S 350mAh 20C Li-Po battery. If using another battery, the bat-
tery must be at least a 2S 350mAh 20C battery. Your battery should be approximately the same capacity, dimension and
weight as the 2S 350mAh 20C Li-Po battery to t the fuselage without changing the center of gravity signicantly.

Preight check
transmitter and model setup
Aileron Elevator Rudder
Control throws
After assembly and prior to your rst ight, make sure all control surfaces respond correctly to your
transmitter by referring to the diagram below.
Tip: The maiden ight should always be
own using low rates, y the aircraft until
you are familiar with its characteristics prior
to trying high rates. Make sure the aircraft
is ying at altitude and adequate velocity
prior to using high rates, as the aircraft will
be sensitive to control inputs with the larger
control surface movements.
The suggested control throw setting for the Pioneer are as follows (dual rate setting):
High Rate
Elevator
Aileron
Rudder
12mm up / down 10mm up / down
12mm up / down 10mm up / down
10mm left / right 8mm left / right
Low Rate
Finding the correct center of gravity is critical in ensuring that the
aircraft performs in a stable and responsive manner. Please adjust the weight
distribution so the aircraft balances in the range stated on the diagram.
• If you cannot obtain the recommended CG by moving the battery
to a suitable location, you can also install a counterweight to achieve
correct CG. However, with the recommended battery size, a
counterweight is not required. We recommend ying without
unnecessary counterweight.
• Depending on the capacity and weight of your
choosen ight batteries, move the battery forward or
backward to adjust the center of gravity.

Before ying the model
Flight tips
Find a suitable ying site
Performing a range check
Monitor your ight time
Find a ying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be
required and have mastered ying your plane in conned spaces, choose a site which is at least the size of two to three
football elds - a ying eld specically for R/C planes is best. Never y near people - especially children, who can
wander unpredictably.
A radio range check should be performed prior to the rst ight of the day. This test may assist you in detecting electronic
problems that may lead to a loss of control- problems such as low transmitter batteries, defective or damaged radio
com- ponents or radio interference. This usually requires an assistant and should be done at the ying site.
Always turn your transmitter on rst. Install a fully charged battery in the battery bay, then connect it to the ESC. In this
process, make sure that the throttle cut functionality is on, and that the throttle stick is secured in its lowest position
other-wise, the propeller/fan will engage and possibly cause bodily harm.
Note: Please refer to your transmitter manual that came with your radio control system to perform a ground
range check. If the controls are not working correctly or if anything seems wrong, do not y the model until you
correct the problem. Make certain all the servo wires are securely connected to the receiver and the transmitter
batteries have a good connection.
Monitor and limit your ight time using a timer (such as a stopwatch or on the transmitter, if available). As modern
Lithium Polymer batteries are not designed to discharge completely, when the battery runs low, the ESC will lower then
completely cut the power to the motors to protect the battery.Often (but not always) power can be briey restored after
the motor cuts off by holding the throttle stick all the way down for a few seconds.To avoid an unexpected dead-stick land-
ing on your rst ight,set your timer to a conservative 4 minutes. When your alarm sounds you should land right away.
Take off
Point the aircraft into the wind while slowly applying power until the aircraft starts to track straight, use the rudder when
necessary. When the aircraft reaches takeoff speed, ease back on the elevator stick until the aircraft is climbing at a
constant rate without decelerating. Climbing at too steep of an angle at the relatively low speeds of a takeoff-climb may
result in an aerodynamic stall.
Flying
Always choose a wide-open space for ying your plane. It is ideal for you to y at a sanctioned ying eld. If you are not y-
ing at an approved site always avoid ying near houses, trees, wires and buildings. You should also be careful to avoid ying
in areas where there are many people, such as busy parks, schoolyards, or soccer elds. Consult laws and ordinances before
choosing a location to y your aircraft. After takeoff, gain some altitude. Climb to a safe height before trying
technical manoeuvres.

Flying tips
Landing
Land the aircraft when you start to feel sluggish motor response. If using a transmitter with a timer, set the timer so you
have enough ight time to make several landing approaches.The model’s three point landing gear allows the
model to land on hard surfaces. Align model directly into the wind and y down to the ground. Fly the airplane down to
the ground using 1/4-1/3 throttle to keep enough energy for proper are. Before the model touches down, always
fully decrease the throttle to avoid damaging the propeller or other components. The key to a great landing is to mana-
ge the power and elevator all the way to the ground and set down lightly on the main landing gear. With some practice,
you will be able to set the aircraft gently on its main gear and hold it that way until the speed reduces enough where
the nose wheel (tricycle landing gear aircraft) or tail wheel (tail draggers) settles onto the ground.
Maintenance
Repairs to the foam should be made with foam safe adhesives such as hot glue, foam safe CA, and 5min epoxy. When
parts are not repairable, see the spare parts list for ordering by item number.
Always check to make sure all screws on the aircraft are tightened. Pay special attention to make sure the spinner is
rmly in place before every ight.

User Manual
Basic parameters
Functionality
Operation instructions
Power and calibration
1. This aircraft is equipped with Vector, an advanced ight control system. The two different ight modes (Stability and
Dynamic) can be toggled via the 2 position switch located on the left shoulder of the transmitter.
Stability mode: Allows for the aircraft to automatically level its wings when no user input is given. This mode is perfect for
begin- ners or as a safety function during loss of orientation.The aircraft will maintain level ight at half throttle, and slowly
increase in nose up attitude when the throttle is advanced above 50 percent.
Dynamic mode: Dynamic mode gives pilots full control over the aircraft without making any control inputs unless the
attitude upset is caused by factors such as wind gusts.
Binding
Connect the battery to the aircraft, turn on the transmitter and simultaneously press the two bind buttons to enter binding
mode.
Transmitter warnings
1. After the transmitter is powered on, an audible signal is given every minute to assist the pilot in keeping track of ight time.
The green status LED indicates that the transmitter is operating normally.
2. When low on power, the transmitter will beep constantly and the status LED will turn red.
3. If the throttle stick isnt at 0 when the transmitter is powered on, the transmitter will beep constantly and the status LED will
turn red.
1. Set the aircraft on a level surface, turn on the transmitter and then power on the aircraft.
2. Wait for the Vector system to self calibrate (rapid red LED ash).
3. After calibration (3 seconds), the aileron and elevator servos will cycle 3 times, indicating successful calibration.
4. Vector status LED:
Stability mode: LED ashes rapidly
Dynamic mode: LED stays on
