Flying Your Aircraft
Consult local laws and ordinances before choosing a fl ying location.
Range Check your Radio System
Before you fl y, range check the radio system. Refer to your specifi c transmitter
instruction manual for range test information.
Just Before Flight
Once the fl ight control system is active, you will normally see the control
surfaces react to aircraft movement.
For your fi rst fl ights with the recommended battery pack (EFLB8003S30), set
your transmitter timer or a stopwatch to 5 minutes.
NOTICE:
Never fl y the aircraft without fi rst setting and activating a timer.
After 5 minutes, land the aircraft. Adjust your timer for longer or shorter fl ights
depending on your preference and battery usage.
Takeoff
NOTICE:
All takeoffs and landings must be done in Multirotor Flight Mode.
Attempting to land in Airplane Flight Mode will damage the motors and nacelles
possibly causing a crash. Crash damage is not covered under warranty.
Place the aircraft on a fl at, level surface with the tail facing you. Set your
transmitter to Multirotor Flight Mode and Stability Mode. Ramp up the throttle
trim to keep the propellers turning.
Tip:
Stability mode is highly recommended for the fi rst few takeoffs and landings,
until you become familiar with how the aircraft reacts to control inputs.
Check that the motor nacelles are in the fully upright position in Multirotor Flight
Mode before applying throttle. Gradually increase the throttle until the model is
approximately 2 ft. (600mm) off the ground. Avoid forcing the aircraft into the air.
Multirotor Flight
Using Stability Mode to begin, try to hold the aircraft in one spot small with
small corrections on the transmitter control sticks. If fl ying in calm winds, the
model should require almost no corrective inputs. After moving the aileron/
elevator stick and returning it to center the model will level itself (when fl ying in
Stability Mode). The model may continue to move due to inertia. Move the stick
in the opposite direction to stop the movement.
After you become comfortable hovering, you can progress into fl ying the model
to different locations, keeping the tail pointed towards you at all times. You can
also ascend and descend using the throttle stick.
Once you are comfortable with these maneuvers, you can attempt fl ying with
the tail in different orientations. It is important to keep in mind that the fl ight
control inputs will rotate with the aircraft, so always try to picture the control
inputs relative to the nose of the aircraft.
NOTICE:
Do not
attempt to fl y backwards at a high rate of speed. While the
aircraft is capable of fl ying backwards while in multirotor mode, the aircraft
becomes more unstable as backward speed increases due to airfl ow over
the fi xed wings.
Transitioning In Flight
To transition to Airplane Flight Mode from Multirotor Flight Mode
change
the fl ight attitude switch on your transmitter to the Airplane Flight Mode. The
throttle will increase slightly and the motor nacelles will rotate forward in three
stages to the airplane fl ight position. The elevons become active. It is normal
to have some slight oscillations in pitch as the aircraft transitions into Airplane
Flight Mode. While in Airplane Flight Mode the main motors use differential
thrust to provide yaw control and the tail motor does not run.
To transition to Multirotor Flight Mode from Airplane Flight Mode
reduce
the airspeed, change the switches on your transmitter to select the Multirotor
Flight Mode and Stability Mode for landing. The throttle will increase slightly
and the motor nacelles will rotate to the vertical position. The tail motor will
power on and the elevons will go to neutral. While in Multirotor Flight Mode
the elevons do not move. All pitch, roll and yaw control is accomplished by
differential thrust and angling of the motors.
NOTICE:
Do not transition to Multirotor Flight Mode at low throttle or lower
the throttle immediately after transitioning to Multirotor Flight Mode. Doing
so will cause a rapid loss of altitude and possibly a crash.
Airplane Flight
Fly the aircraft and trim it for level fl ight per the
Trimming Your Aircraft
section.
The Convergence fl ies in a very similar manner to any other fi xed-wing aircraft.
It is capable of a wide range of aerobatic maneuvers including loops, rolls
and spins. Additionally, the differential thrust of the motors allows for unique
spinning and tumbling maneuvers.
Landing
NOTICE:
All takeoffs and landings must be done in Multirotor Flight
Mode.
Attempting to land in airplane mode will damage the motors and rotation
mechanisms possibly causing a crash. Crash damage is not covered under warranty.
Transition the aircraft into Multirotor Flight Mode and bring it into a low hover.
Slowly lower the throttle to descend to a soft landing.
NOTICE:
If a crash is imminent, activate the throttle cut feature. Failure to
do so could result in extra damage to the airframe, as well as damage to the
ESCs, motors and motor nacelles.
NOTICE:
Crash damage is not covered under warranty.
NOTICE:
When you are fi nished fl ying, never leave the aircraft in direct sunlight
or in a hot, enclosed area such as a car. Doing so can damage the aircraft.
Low Voltage Cutoff (LVC)
The average fl ight time with a mixture of hovering and airplane fl ight using the
recommended fl ight battery is approximately 5 minutes.
The fl ight controller protects the fl ight battery from over-discharge using
Low Voltage Cutoff (LVC). When the fl ight battery is drained to LVC the fl ight
controller will automatically transition the motors into Multirotor Flight Mode
and change to Stability Mode. The remaining battery will last less than a
minute, so land the aircraft as soon as possible.
When the battery reaches LVC in Multirotor Flight Mode the motor power is
sharply reduced for an instant to warn the pilot the model has entered LVC and
the model is set to Stability Mode if it isn’t already. In this fl ight condition the
motors will slowly lose power until the ESCs cutoff. If you notice the motors cut
power for a brief moment, land immediately and re-charge the fl ight battery.
After landing, disconnect and remove the Li-Po battery from the aircraft to prevent
trickle discharge. Charge your Li-Po battery to approximately half capacity before
storage. During storage, make sure the battery charge does not fall below 3V per
cell. LVC does not prevent the battery from over-discharge during storage.
NOTICE:
Repeated fl ying to LVC may damage the battery.
Tip:
Monitor your aircraft battery’s voltage before and after fl ying by using a
Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the foam material in this aircraft, repairs to the foam can be made
using virtually any adhesive (hot glue, regular CA, epoxy, etc). When parts are
not repairable, see the Replacement Parts List for ordering by item number.
For a listing of all replacement and optional parts, refer to the list at the end
of this manual.
