Usetheincludedadhesive‐backed‘hook‐and‐loop’materialtoinstallthereceiver(not

thereceiveronthesideofthefuselageoppositeoftheESC.Plugthe3‐wireleadfromtheESC
intothe‘throttle’channelandtheelevatorservoleadintothe‘elevator’channelonthe


NOTE:It’simportanttoensurecorrectpolaritywhenpluggingtheleads/connectorsinto
thereceiver.Refertothemarkingsonthereceiver(orthemanualforthereceiver)to
identifywhichpinsaccepttheblackcolor(negative/ground),redcolor(positive)andwhite

Wealsosuggestpluggingtherudderservoleadintothe‘aileron’channelonthereceiver.It’s
typicaltousethe‘aileron’controlstick/channeltocontroltherudderfor‘3‐channel’models


•YoumustchargetheLiPobatteryinasafeareaawayfromflammablematerials.
•NeverchargetheLiPobatteryunattendedatanytime.Whenchargingthebattery
youshouldalwaysremaininconstantobservationtomonitorthechargingprocess
andreactimmediatelytoanypotentialproblemsthatmayoccur.
•Afterflying/dischargingthebatteryyoumustallowittocooltoambient/room
temperaturebeforerecharging.Also,itisNOTnecessaryorrecommendedto
dischargethebattery‘completely’beforecharging(LiPobatterieshaveno‘memory’
andit’ssafetochargepartiallydischargedbatterieswhenusinganappropriate
chargerandsettings).
•Tochargethebatteryyoumustuseonlytheincluded205C2‐Cell/2S7.4VLiPo,0.5A
DCBalancingCharger(AZSC205C)orasuitablycompatibleLiPobatterycharger.
Failuretodosomayresultinafirecausingpropertydamageand/orpersonalinjury.
DONOTuseaNiCdorNiMHcharger.
•Ifatanytimeduringthechargeordischargeprocessthebatterybeginstoballoonor
swell,discontinuechargingordischargingimmediately.Quicklyandsafely
disconnectthebatterythenplaceitinasafe,openareaawayfromflammable
materialstoobserveitforatleast15minutes.Continuingtochargeordischargea
batterythathasbeguntoballoonorswellcanresultinafire.Abatterythathas
balloonedorswollenevenasmallamountmustberemovedfromservice
completely.
•Storethebatterypartiallycharged(approximately50%charged/3.85Vpercell),at

•Whentransportingortemporarilystoringthebattery,thetemperaturerangeshould
befromapproximately40–100°F.Donotstorethebatteryormodelinahotgarage,
carordirectsunlightwheneverpossible.Ifstoredinahotgarageorcarthebattery
canbedamagedorevencatchfire.
•Donotover‐dischargetheLiPoflightbattery.DischargingtheLiPoflightbatterytoa
voltagethatistoolowcancausedamagetothebatteryresultinginreducedpower,
flightdurationorfailureofthebatteryentirely.

LiPocellsshouldnotbedischargedtobelow3.0Veachunderload.Inthecaseofthe
2‐Cell/2S7.4VLiPobatteryusedtopowertheGamma370youwillnotwanttoallow
thebatterytofallbelow6.0Vduringflight.

Theincluded20‐AmpBrushedMotorESC(AZS1210)featuresa‘soft’lowvoltage
cutoff(LVC)thatsmoothlyreducespowertothemotor(regardlessofthepower
levelyouhavesetwiththeleft‐hand/throttlestick)toletyouknowthevoltageof
thebatteryisclosetothe6.0Vminimum.However,evenbeforethisreductionin
power,ifyoufindthatmorethanthetypicalamountofthrottle/powerisrequired
tocruiseorclimbyoushouldlandthemodelanddisconnectthebatteryimmediately
topreventover‐discharge.

AndwhileitispossibletocontinueflyingthemodelafterthesoftLVCoccurs,thisis
NOTrecommended.Continueddischargingcanresultinreachingthe5.0V‘hard’LVC
whichmaycausepermanentdamagetotheLiPobatteryresultinginreducedpower
andflightdurationduringsubsequentfights(orfailureofthebatteryentirelywhich
isnotcoveredunderwarranty).

Also,itisnotrecommendedthatyouflytothesoftLVCeverytimeyoufly.Instead
youshouldbeawareofthepowerlevelofthebattery/airplanethroughoutthe
flight,andifatanytimetheairplanebeginstorequiremorethrottle/powerthan
typicaltomaintaincruiseorclimbyoushouldlandtheairplaneanddisconnectthe
LiPobatteryimmediately.ConstantlydischargingthebatterytothesoftLVCcanstill
causepermanentdamagetothebatterysoit’sbesttouseatimerorstop‐watchto
timethedurationofyourflightsandtostopflyingatareasonabletimebeforethe

IMPORTANTNOTE:DONOTSTORETHELIPOFLIGHTBATTERYFULLYCHARGED.
ForimprovedsafetyandlongevityoftheLiPobatteryit’sbesttostoreitonlypartially
chargedforanylengthoftime.StoringtheLiPobatteryatapproximately50%charged
(whichisapproximately3.85Vpercell)istypicallybest,howeveritwilltakesome
carefulmanagementofthechargetimeandtheuseofavoltmetertoachievethis
voltage.

Ifyouhavetheequipmentandskillstoachievethe50%chargelevelforstorageitis
recommended.Ifnot,simplybesuretonotstorethebatteryfullychargedwhenever
possible.Infact,aslongasthebatterywillbestoredatapproximatelyroom
temperatureandfornomorethanafewweeksbeforethenextuse,itmaybebestto
storethebatteryinthedischargedstateafterthelastflight(aslongasthebatterywas

approximately30‐45minutestofullychargeamostlyorfullydischarged(notover‐


For‘fast’chargingwerecommendusingtheRadient™PrimalorAscendchargers.Both
