The Spektrum DX6e 6 Channel Full Range DSMX Transmitter gives you the unbeatable response of DSMX technology, the simplicity of Spektrum AirWare programming software and many other features you can't find on other "budget" radios.Features at a Glance:Patent-pending gimbal design with spring configuration switchDSM2/DSMX Wireless trainer linkVirtually unlimited model memory-transmitter stores up to 250 models and only populates the model list with models the user has configuredAirplane, Helicopter, Sailplane and Multirotor programmingBuilt-In Telemetry7 airplane wing types and 6 tail types2 swashplate types4 sailplane wing types and 3 tail typesMultirotor flight mode setup7-point throttle curves for airplanes and helicopters7-point pitch and tail curves for helicoptersCross-platform model sharing with other Spektrum transmitters4 AA batteries includedEN328 compatible In Depth Features:Airplane, Helicopter, Sailplane and Multirotor Programming: The DX6e comes equipped with the programming you need to fly almost anything. And because it's based on the same Spektrum AirWare software used in most other Spektrum transmitters, you can share model setups with just about any Spektrum user you meet.AIRPLANE PROGRAMMING7 Wing Types: Normal, Dual Aileron, Flaperon, 1 Aileron 1 Flap, 2 Aileron 1 flap, Elevon A, Elevon B6 Tail Types: Normal, V-Tail A, V-tail B, Dual Elevator, Dual Rudder, Dual Rudder/ElevatorFlap System with Elevator Compensation3 Flight ModesDual Rates and Expo7-Point Throttle Curve3 Preset Mixes: Rudder-to-Aileron/Elevon, Aileron-to-Rudder, Elevator-to-Rudder4 Programmable Mixes – Normal or CurveHELICOPTER PROGRAMMINGGyro7-Point Throttle Curve7-Point Pitch Curve7-Point Tail Curve2 Swash Plate Types: Normal, 3-Servo 120˚3 Flight Modes + Throttle HoldDual Rates and ExpoCyclic-to-Throttle and Swashplate Timing Mixes4 Programmable Mixes – Normal or CurveSAILPLANE PROGRAMMING4 Wing Types: Single Aileron, Dual Aileron, 2 Aileron 1 Flap, 2 Aileron 2 Flap3 Tail Types: Normal, V-Tail A, V-Tail BCamber SystemCamber Preset5 Flight ModesDual Rates and ExpoDual Rates and Expo4 Preset Mixes: Aileron-to-Rudder, Aileron-to-Flap, Elevator-to-Flap, Flap-to-Elevator4 Programmable Mixes – Normal or CurveMULTIROTOR PROGRAMMINGMultirotor Channel Inputs – ALT (Altitude), ROL (Roll), PIT (Pitch), YAWMultirotor Checklists and WarningsSimplified Multirotor Flight Mode Setup and Switch Assignment250-Model Memory: The enormous capacity of the DX6e's on-board memory means you will rarely, if ever, need to juggle models between transmitter memory and your SD card. The model memory menu is easy to navigate too. Only memory slots with model settings saved to them will appear. You won't have to scroll through empty slots or move models around if one is deleted.Built-In Telemetry: The built-in telemetry feature can give you real-time information on things like battery voltage, signal quality, motor temperature and more.* You can also program alerts that let you know when specific telemetry values reach or exceed limits you define. * Requires telemetry sensors and a telemetry-enabled receiver.Patent-Pending Gimbal Design with Spring Configuration Switch: The DX6e's patent-pending gimbal design lets you change gimbal spring configurations simply by moving a slider switch on the back of the transmitter. No tools are required. Just select the spring configuration that matches the mode you are using and model type you are flying. That's it.There are four spring configurations to choose from:Normal Throttle for Modes 2 and 4 (Air, Heli and Sailplane Model Types)Spring-Centered Throttle for Modes 2 and 4 (Multirotor Model Type)Spring-Centered Throttle for Modes 1 and 3 (Multirotor Model Type)Normal Throttle for Modes 1 and 3 (Air, Heli and Sailplane Model Types)The slider switch is protected by a hinged cover that prevents you from accidentally changing spring configurations in flight.Wireless Trainer Link: The wireless trainer link gives instructors the option to wirelessly ''buddy box'' with another DSMX/DSM2® transmitter. Once bound to another transmitter, ModelMatch™ technology will allow the DX6e to re-link without having to go through the bind process again.Specifications:Band: 2.4GHzChannels: 6Model Memory: 250Modulation: DSMXRange: FullTelemetry: CompatibleTransmitter (Tx) Battery Type: AAType: 6-channel Aircraft Transmitter
