FLYING YOUR QQ YAK 55 10E SUPER PNP
Selecting a Flying Site
Selecting a flying site is critical to a successful flight. Airplanes
require a lot more room than other R/C products, therefore, a
neighborhood or parking lot is less than ideal. A large open field
with short grass and generous overfly area are the best candidates if
no AMA field is available in your area. Know your overfly area -
ensure that there are no houses, playgrounds, or other buildings that
may be damaged if the airplane were to crash.
Takeoff
Taxi or place the aircraft on the runway centerline, with the nose
pointed into the wind. Select Select Flight Mode 1 with the gyro kill
switch set to gyro on, then set the throttle trim so that the motor
spins at its lowest RPM without stopping. Smoothly advance the
throttle to full while maintaining directional control with the rudder
and slight back pressure on the elevator. The airplane should lift off
smoothly before the throttle is fully open. Fly in Flight Mode 1 until
the aircraft is fully trimmed (see special trimming instructions), and
you are comfortable with its handling, then explore the other modes
as desired.
Flying
Altitude is your friend on the first flight. Briskly climb to a safe
altitude and trim the airplane out. The airplane should fly straight
and level at 2/3 to 3/4 power with no hands on the transmitter. Try
some basic maneuvers, and slowly progress into the airplane’s flight
envelope as you become more comfortable with the airplane’s flight
qualities and perfect your setup. Note: If at any time you experience
unexpected control system inputs or oscillations, switch off the gyro
function using your gyro kill switch (assigned on page 12), land and
troubleshoot the issue.
Landing
Be mindful of your flight time and allow adequate battery reserve for
a couple of go-arounds, if necessary, on the first few flights. Select
Flight Mode 1 and slow the airplane and align with the runway, into
the wind. The airplane should descend smoothly in this
configuration with proper airspeed. Once you are close to the
ground, gradually close the throttle fully and begin to smoothly
apply up elevator as required to arrest descent and the airplane
should gently touch down with a short roll out.
Trimming
The first several flights on your new QQ Yak 55 10E Super PNP
should be dedicated to trimming and setup. Fly the airplane at
2/3 power in any Flight Mode you are comfortable flying in,
and trim for level flight. DO NOT CHANGE FLIGHT MODES.
Land, adjust linkages or execute Quick Trim (see below) and
return the trim and/or sub-trim to zero and fly again.
Repeat process until the airplane flies hands off, straight
and level.
Transmitter trim or sub-trim will cause trim shifts when
different flight modes are selected. To eliminate this trim shift,
the model should be mechanically trimmed, or Aura “Quick
Trim” may be used instead.
CAUTION
USE CAUTION WHEN FLYING YOUR QQ YAK 55 10E SUPER PNP
IN MODE 3 AT HIGH AIRSPEEDS. DOING SO CAN INDUCE
CONTROL SURFACE OSCILLATIONS AND MAY CAUSE A CRASH.
Aura Quick Trim
The Aura 8 features a Quick Trim Mode that eliminates the need for
mechanical linkage adjustments during test flights. Aura will learn
the trim values from your transmitter, and apply them to the control
surfaces at power up when enabling quick trim mode.
NOTE: Quick Trim can also be used BEFORE flying to make small
changes to center the control surfaces before flight.
1. Fly the airplane in your preferred Flight Mode at 2/3 power. Trim
the aircraft with the transmitter trimmers and land. DO NOT
CHANGE FLIGHT MODES.
2. Power off the QQ Yak 55 10E Super PNP. Insert a bind plug into
Aura Port S3 (you will need to remove the servo lead that is
currently in S3). Check the transmitter is on and re-power the
Aura to enter Quick Trim.
3. Wait 5 seconds for the Aura to completely initialize. Confirm
Quick Trim mode is active by checking the Blue LED is slowly
flashing.
4. Remove the bind plug from Aura Port S3 to save your trim
settings. Re-install the servo that was previously removed into
port S3. Removing the bind plug stores the current trims in the
Aura. The Blue LED will flash quickly after control surface trim
values are stored. While the trim values are stored in Aura, they
are not applied to the control surface(s) until the Aura is re-
powered.
5. Remove power from the QQ Yak 55 10E Super PNP and center all
control surface trims on the transmitter.
6. Re-power the QQ Yak 55 10E Super PNP. The control surfaces
should be unchanged even though the trim has been centered
on the transmitter.
7. Switch between other Flight Modes to ensure you do not see
any changes in trim.
NOTE: QUICK TRIM MAY BE REPEATED AS NEEDED FOR FINE
TUNING, OR IF CHANGES TO THE AIRCRAFT ARE
MADE.
NOTE: ENSURE AILERON/ELEVATOR/RUDDER SUB-TRIMS ARE
AT ZERO IN THE TRANSMITTER BEFORE FLYING FOR
THE QUICK TRIM PROCESS TO WORK PROPERLY.
