Briefintroduction
1. Functionandfeatures
T380Squad‐copterisamid‐levelaircraftdesignedmainlyforFPVenthusiasts.
ThismeansthattheT380SisNOTforbeginners.TheT380Soffershighly
efficientflightbyusing8inch,slowturningpropellersonbrushlessmotors.
TheT380Sisalsoverystable.Thestabilityisachievedbyusingahigh
performanceMEMSsensorfor6DOFstabilizationresultinginlowdriftand
offeringshockresistance.TheT380Sissimpletoflyandrequiresatleasta
four(4)channelradiotransmitter.Ourincludedradioreceiverandcore
systemiscompatiblewithmostradiotransmittersystems.TheT380Siseasy
tooperateandiscapableoftakingoffvertically,hovering,flyingforward,left,
