ESC/Receiver Arming, Battery Installation and Center of Gravity

NOTICE: Always keep material or debris away
from the intake. When armed, the rotor will turn in
response to throttle movement and could ingest
loose objects.
The UMX A-10 requires a 3S 850mAh Li-Po battery
with an IC2 or EC2 connector (SPMX8503S30
recommended). Add a piece of hook and loop
material (hook side) to the side of the fuselage
along the battery compartment. Add a small piece
of hook and loop material (soft side) to the side of
the battery at the same end as the power lead. It is
important to only use a small piece to prevent the
battery from shifting. Using too large of a piece will
make it difficult to remove the battery and may lead
to fuselage damage.
Arming the ESC/receiver also occurs after binding
as previously described, but subsequent connection
of a flight battery requires the following steps.
1. Lower the throttle and throttle trim to the
lowest settings on your transmitter.
2. Remove the battery/canopy hatch from the
fuselage and install a flight battery (A) all the
way to the back of the battery comportment.
Center of Gravity (CG)
The CG location is 32-34mm back from the
leading edge of the wing at the root. Balance the
airplane inverted on this recommended CG mark
with all landing gear installed. Adjust as needed by
sliding the battery forward or back.
3. Power ON your Transmitter,
then wait 5 seconds.
4. Connect the battery to the ESC, noting proper
polarity. Keep the plane immobile and away
from wind for 5 seconds to allow the AS3X
system to initialize.
A successful connection is indicated by:
– A series of tones
– A continuous LED
CAUTION: Always disconnect the Li-Po
battery from the ESC when not flying to
eliminate power supplied to the motor. The ESC
does not have an arming switch and will respond
to any transmitter input when a signal is present.
CAUTION: Always disconnect the Li-Po
battery from the ESC when not flying to avoid
over-discharging the battery. Batteries discharged
to a voltage lower than the lowest approved
voltage may become damaged, resulting in loss of
performance and potential fire when batteries
are charged.
