Dualsky XM5050EA-12 610kv Brushless Motor

The new V3 Dualsky XM5050EA-12 features a new Durotate rotor with an optimised back cover that reduces air noise, a new front cover that offers better heat dissipation and a higher density rotor and shell that reduces vibration. Add to this the use of thicker wire with high temperature resistance and the net result is more power and improved efficiency.

Features

  • Higher grade curved magnets
  • High efficiency, high density Silicon steel
  • Tighter tolerances allow a smaller air gap between the stator and the rotor
  • High grade enamelled silicon coated wire
  • Reduced air noise, less drag, more power
  • Lightweight
  • M8 propellor mount

Spektrum AR8360T 8ch Air Receiver with SAFE Technology and Telemetry RX.

The Spektrum AR8360T 8 Channel AS3X/SAFE Telemetry Receiver is a DSM2® and DSMX® capable receiver with a compact footprint to fit in a wide range of aircraft. The AR8360T is a full range 8 channel receiver with built in AS3X stabilization, which counters the effects of wind, turbulence and torque using a 3-axis MEMS gyro and exclusive flight control software tuned by expert RC pilots. There is no delay in control response or limit on control throws. You'll simply feel like you're flying an expertly tuned model that does exactly what you want

Features

  • Compatible with all Spektrum™ DSM2 and DSMX transmitters
  • Built in AS3X Stabilization System with SAFE flight envelope protection
  • AS3X and SAFE set up through forward programming directly from your Spektrum transmitter*
  • Compact footprint fits most parkflyer size, sport class and giant scale models
  • Features full range telemetry, integrated barometer to provide altitude and vario telemetry data without the need of additional sensors
  • Bind button allows for easy binding and eliminates the use of bind plug
  • Two external antennas will ensure secure RF coverage from all angles of the aircraft
  • Additional RF path redundancy with an additional SRXL2 Remote Receiver (SPM9747 or SPM4651, sold separately)
  • Ready to use with Spektrum Smart ESC for one-wire telemetry data without the need of modules, links and wires.
  • End pin output pins for easy and compact installation
  • Forward Programming capable for setting individual failsafe parameters per channel and more

Product Information

The AR8360T features a full range telemetry, integrated barometer to provide altitude and vario telemetry data without additional purchase. Included XBUS and temperature ports can be used to add additional telemetry sensors available separately. It also features an SRXL2 port for an SRXL2 Remote Receiver (SPM9747 or SPM4751T), available separately, to add additional RF path redundancy. An SRXL2/Bind/Program/Batt servo header is available to connect smart devices, program and update the receiver, bind with a traditional bind plug, or connect a battery. The AR8360T also features a bind button for easy binding with no plugs necessary and offers both SmartSafe™ technology and Hold Last as well as preset failsafe types set through forward programming.

Please Note: The DX7S and DX8 Gen 1 Spektrum Transmitters will not display Altitude or Variometer telemetry with the AR8360T receiver.

AS3X® TECHNOLOGY (3-AXIS STABILIZATION)

Exclusive Spektrum™ AS3X® technology enhances flight stability by countering the effects of wind, turbulence, and other outside forces to help your aircraft fly smoothly and with precision. You'll feel like you're piloting an expertly tuned model that performs exactly as you want.

FORWARD PROGRAMMING

You can configure the AR8360T receiver wirelessly, directly from any compatible Spektrum™ transmitter, through the Forward Programming menu. No separate computer or mobile device is needed for setup and adjustments.

  • Support for different multicopter types – from tricopters to octocopters.
  • Up to 3 adjustable flight modes, options for stabilizing the horizon and altitude.
  • Inflight gain tuning using free channels.
  • Using the latest 3axis gyroscope, 3axis accelerometer and barometric altimeter.
  • Support for LED strip consisting of WS2812 chips.
  • Support for external camera gimbal driven by servos.

  • Full setup options with DC/DS transmitters or via PC.
  • Available telemetry: Receiver voltage, signal quality, Gforce, attitude orientation.
  • Support of telemetry and up to 3 sensors connected directly.

Product Information

7 channel full-range receiver with integrated Assist stabilisation, compatible with JETI EX & EX Bus protocols. Supports telemetry functions and stabilisation of airplane and multicopter models.

The REX A receivers enhance the REX series of receivers and extend it with the intelligent flight stabilization feature, which is designed for airplane models and multicopters. This stabilization works in all three axes of the model and facilitates flying in windy or otherwise challenging conditions. Aerobatic manoeuvres will be more accurate and smoother. With the help of several flight modes, which are also suitable for beginner pilots, flying practice will be really easy.

Multiplex Rx-9-Dr M-Link 2.4ghz Receiver, Clearance

A high-quality 9-channel receiver built in state-of-the-art SMD technology in MULTIPLEX 2.4 GHz M-LINK technology for all types of models. Thanks to the compact dimensions with in-line plug configuration, it also fits into models with cramped installation conditions. As a dual receiver, this receiver has two complete, parallel-operating receiver circuits (receiver diversity). This is combined with a special signal pre-amplification for maximum sensitivity and thus for excellent reception quality and maximum system range.

Features

  • HOLD / FAILSAFE function
  • Telemetry / return channel capability
  • Integrated sensor interface for connecting external sensor modules (max. 16)
  • Tworeceiver diversity operation prepared (diversity cable required)
  • Integrated error counter / data logger (voltage and signal error)
  • MULTImate compatible
  • Integrated PC interface
  • SRXL serial servo output for Flybarless systems.
