The Spektrum™ AR20310T PowerSafe receiver is a feature-packed 20 channel receiver with integrated full-range telemetry. Each come with built-in connection ports for RPM, Flight Pack Voltage and Temperature sensors as well as an X-Bus port for additional telemetry options.

If you have a DSMX®/DSM2® transmitter capable of 11ms frame rates, the AR20310T will deliver lightning-fast input-to-output response that is perfect for high-performance applications such as aggressive 3D , IMAC, and Turbine Airplanes. Each receiver includes 2 remote receivers that take advantage of Spektrum MultiLink™ technology. This patented technology eliminates the reflected signal fading and antenna blind spots that can affect all 2.4GHz systems.

A ground-breaking feature introduced on the AR20310T PowerSafe Receiver is the built in receiver battery energy sensors. Giving pilots added awareness of the load and mAh used by the servos, retracts, lights, etc. used by each battery. Current Gen 2 Radio firmware already supports this function. Also, as with most of the current receiver line up, these feature a bind button that gives pilots an easy alternative to the age old bind plug.

Super comfortable model memory management

The COCKPIT SX 9 is equipped with 200 internal model memories, the model memory is stored on the internal SD card in the .xml format.A comfortable model memory management on the PC via USB mass storage is therefore easily possible.

Outstanding speech output

With more than 450 words, numbers and phrases, it is one of the most advanced systems of its kind ever installed in a hand-held transmitter.
The use of this system allows COCKPIT SX 9 pilots to take critical telemetry data and station functions without turning away the view from flying..The COCKPIT SX 9 will tell you the specific sensor values if necessary. Once an alarm is triggered, you do not have to look at the display to see what's going on, the COCKPIT SX 9 tells you.

Back channel / Telemetry

When a telemeter capable receiver is used, the current voltage of the receiver power supply is displayed on the display of the transmitter.If an adjustable minimum voltage is exceeded, an acoustic signal warns of a vacant receiver battery. without a sensor, the connection quality (LQI) on the transmitter display can also be displayed in% values.
An additional security solution!
In addition, up to 8 telemetry data can be displayed on the display (depending on the sensors connected to the receiver, eg voltage, current, temperature, etc.) (application examples: motor temperature, drive voltage, current consumption of the drive).The storage of the telemetry data can be found in the model instead of in connection with the optional MULTIPLEX FlightRecorder (# 8 5420).Display of the sensor values in the display is freely configurable, dynamic adjustment of the displays

Wireless teacher / student operation

The COCKPIT SX 9 M-LINK can be standard as both teacher and student transmitter.All L / S-compatible M-LINK transmitters can be used as a student or teacher transmitter.The optional COPILOT module (# 4 5184) is required for the teacher operation.The COCKPIT SX 9 operates with selective L / S operation.This permits the transfer of individual control functions to the student, either individually or as a whole, depending on the learning progress of the student.Only by touching the sticks the teacher can take over the model again.

Dualsky 3S Li Po

Overview

A quality lightweight high discharge (150C) 3S LiPO

Product Information

Dualsky has produced a great battery for small electric models where a high discharge rate is desired. With the 150C discharge capability you can draw up to 72A from this 49g battery. And it can be charged at 12C (less than 10 minutes) 

It comes fitted with an XT60 connector that allows the high current draw but you can change it to something smaller in a lower current environment.

Thats all from the Thermal Circle. Happy Safe and Successful Soaring. Hayden Daley 2022.
