Solution
Aircraft will not
“throttle up”
but all other
controls seem
to function.
• User did not lower throttle trim and
throttle stick prior to initializing the
aircraft.
• Throttle channel is reversed.
Note: Futaba transmitters (equipped
with Spektrum modules) may require
you to reverse the throttle channel.
• Lower throttle stick and
throttle trim to their lowest
settings.
• Reverse throttle channel
on specific transmitter if
applicable.
LED on aircraft
remains flashing
and cannot be
controlled by
transmitter.
• User did not wait at least 5 seconds
after powering the transmitter prior
to connecting the flight battery to
the aircraft.
• User bound the aircraft to a different
transmitter.
• Transmitter was too close to
aircraft during the initialization
process.
• Unplug, then reconnect
flight battery.
• Rebind aircraft to your
desired compatible
transmitter.
• Move transmitter
(powered on) a few feet
from the aircraft prior to
reconnecting the flight
battery.
Controls appear
to be reversed
after binding to a
different
transmitter.
• User did not initially set up
transmitter prior to binding to the
aircraft.
• See the “Advanced
Programming” section of
this manual.
Aircraft does
not function
after connecting
flight battery and
aircraft smells
burnt.
• User may have accidentally plugged
the flight battery in the wrong
polarity.
• Replace AR6400T board
and ensure the RED
polarity marks are facing
the same direction when
connecting the flight
battery to the AR6400T
board.
The system will
not connect
• Your transmitter and receiver are too
close together. They should be 8 to
12 feet apart.
• You are around metal objects.
• Model selected is not the model
bound to.
• Your transmitter was accidentally
put into bind mode and is not bound
to your receiver anymore.
• Move transmitter 8 to 12
feet from receiver.
• Move to an area with less
metal.
• Check model selected and
ensure you are bound to
that model.
• Rebind your transmitter
and receiver.
Receiver quits
responding
during operation
• Inadequate battery voltage
• Loose or damaged wires or
connectors between battery and
receiver
• Charge batteries This
receiver requires at least
3.2V to operate. An
inadequate power
supply can allow voltage to
momentarily drop below
3.2V and cause the receiver
to brown out and reconnect.
• Check the wires and
connection between battery
and receiver. Repair
or replace wires and/or
connectors
