1.Introduction
A3SuperisthelatestRCflightcontrolsystemofEAGLE’sA3Series.Itisdesignedespeciallyforfixedwing.
With an integratedbuiltinhighprecision6axis(3gyro+3acc)MEMSsensorandadvancedattitudeandPID
control algorithm, the controller can accurately detect the angular velocity and attitude of the plane and issue
commandstoallservos,whichenablesthebalanceandstabilitythroughouttheflight.A3Superprovidesfeatures
ofdeltawing(flyingwing),vtail,remotemastergainadjustmentandseparatedualaileronandelevatorcontrol.
ItcanbeusedinnearlyanytypeofRCplanes.
A3 Super offers four flight modes, including Normal Stabilization Mode, 3D Attitude Locking Mode,
Selfbalance Modeand Gyro Deactivated Mode. It also provides three kinds of control behavior including
StableMode,NormalModeandSportModetomeettheneedofvarioususer’srequirement.
We also provide you a program card. Without connecting to a PC, you can easily setup all the functions and
parametersevenintheoutdoorflight.ThefirmwarecanbeupgradedthroughtheUSBadapter.Pleasecheckout

6.5.PowerSupply
Thecontrollerispoweredthroughthe[BATT]pins.Toachieveit,youcanconnectitdirectlytoanyidlechannel
ofthereceiverusingtheincluded3wirereceivercable,ortoanindependentBEC.Thevoltagerangeis5to6V.If
aBECisusedasthepowersupply,pleasemakesurethatthevoltagenotexceedingtheworkingvoltagepermitof
your servos, and verify that the BEC have sufficient capacity to provide working current for all the electronic
devicesontheplaneespeciallywhenusingseveralhightorqueservos.
6.6.FlightModeChannel(FMOD)
[FMOD]isusedforswitchingtheflightmode.Wehaveassigneda3positionswitchtoitasmentionedabove.
Theexpectedflightmodecanbepresetinthefunction"FlightMode"oftheprogramcardorconfigtool.System
will default to the mode which assigned to position1 if you leave this pin unconnected. Even so, it is
recommendedthat you always usean
independent channel to switch the
modeinflight.
6.7.MasterGainControlChannel(GAIN)
[GAIN]isusedtocontrolthemastergainremotely.Inthiscase,weuseaknob(RD)tomakealinearadjustment
of the gain. Surely a 3position switch can be used instead to get a 3level gain control.. Once connected, the
master gain will be controlled bythe transmitterdirectly. Only when the pin is disabled or unconnected, the
mastergaincanbemodifiedviatheprogramcardorconfigtool.
6.8.DualAileron&DualElevator
AtruedualaileronandelevatorsystemisavailablenowonA3Super,theOUT4isforthe2ndaileronservoand
the OUT5 is for the 2nd elevator servo. Mostly we use two aileron servos with single aileron input, in this
condition,youjustneedtoplugthetwoaileronservosintoOUT1andOUT4respectively.TheOUT4willbecome
a mirrorofOUT1bythesoftwareautomatically, which canavoidthehassleusingaYextensioncable.Thisis
verysimilarinconnectingthedualelevator.
The dual channelsshare thesamesettings,suchas servo limits, gyro directionandgainsettingandso on.For
example,ifyousettheservolimitsofaileronchannelto ±80%,themaximumtravelofbothaileronservoswill
be ±80%.
Usuallythe2servosshouldbeinstalledsymmetricallyonthebothsideofthewing,butyoucanmakethem
inanopposite directionifyoulike. The separate gyroreversingfor AIL2andELE2 will helpyougetthe
correctresult.

12.6.ServoLimits
This function is used to set the mechanical limits for aileron, elevator and rudder servos. The max limit is
determined by the maximum possible control travel of the mechanism. The limits can be set between 0100%
corresponding to the pwm pulse length from 1020 to 2020μs. The default setting is 100%. When adjusting,
switch the controller to the 3D flight mode first, move the
