MICROBEAST PLUS with firmware version 5.4.x offers the possibility of forwarding telemetry data from telemetry capable devices to the receiver, so you can display telemetry data in your transmitter. Since there are no uniform specifications for telemetry data protocols, MICROBEAST PLUS acts as middleware between the systems. A large number of different sensor data can be received, which is converted internally into a uniform format and then forwarded and processed specifically for the receiving remote control system. The typical application is transmitting battery data from the speed controler of an electric model (battery voltage, power draw, power consumption, ESC temperature, ...) to the radio. So the pilot gets detailed insights of battery status and knows when it's time to land.

The following speed controllers/sensors can be used as telemetry data source at the moment:

  • Hobbywing® Platinum (V4/V5)
  • Kontronik® JIVE/PowerJIVE/HeliJIVE
  • Kontronik® JIVE Pro/Kosmik
  • Scorpion® Tribunus II ("UnSc" mode)
  • speed sensor connected at RPM input


The following radio systems can be used to display telemetry data at the moment:

  • Jeti® EXBUS
  • Spektrum® SRXL2


Please note that telemetry capability must be purchased as additional feature for your MICROBEAST PLUS. After upgrading the feature you must install the firmware with telemetry support by StudioX software. For devices with PROEDITION firmware it is already included.



Adjustment on the device

After receiver scan and function assignment the Menu Point M will open, in case you're using a Spektrum® SRXL2 or JETI® EXBUS radio system. If needed you can directly get to this screen without changing your basic radio setup by clicking the button "Telemetry" in overview screen of RECEIVER MENU.

To select the connected ESC/telemetry data source move the rudder stick repeatedly in one direction until the Status LED lights in the correct color:

Status-LED Telemetry data source
off no telemetry/use RPM signal
purple flashing Hobbywing® Platinum V4
purple Hobbywing® Platinum V5
red flashing Kontronik® JIVE/PowerJIVE/HeliJIVE
red Kontronik® JIVE Pro/Kosmik
blue Scorpion® Tribunus ("UnSc" mode)



Please note there are some additional settings for telemetry available:

  • In GOVERNOR MENU you can use the signal divider and gear ratio adjustment to calculate the rotor head speed from the incoming motor speed. Most ESCs will send the electrical motor speed on the telemetry channel only, so you must divide the motor speed by the number of magnet pole pairs and by the main gear ratio of your helicopter, in order to display the rotor speed. See GOVERNOR MENU E and GOVERNOR MENU F for more details.
  • Some ESC do not calculate the current consumption (Hobbywing®, Kontronik® Jive). Here MICROBEAST PLUS will do the work and calculate the current consumption using the instant current values. Anyhow, results may vary as speed controllers usually measure the motor current but not the battery current. So we added the parameter Capacity correction which allows to compensate the offset. I.e. when telemetry shows 3600mAh of current consumption, but in reality you did charge 4000mAh back into your battery after the flight, you can increase the Current correction by 10% to 110 in order to get proper reading the next time. Please note this very special value can only be set by using StudioX!


Setup with StudioX

After receiver scan and function assignment an additional setup screen for telemetry will open, in case you're using a Spektrum® SRXL2 or JETI® EXBUS radio system. If needed, also you can directly get to this screen without changing your basic radio setup by clicking the button "Telemetry" in overview screen of RECEIVER MENU.

  • Choose the connected ESC/telemetry data source by pressing the corresponding button.
  • The option Capacity correction can be used to adjust the displayed power consumption in case it does not match the real capacity you see when recharging your battery after the flight. The default value is 100%. If the displayed capacity is lower than the real power consumption increase the value, in case the displayed capacity is too high, decrease this value. Please note this parameter is only effective for Hobbywing® and Kontronik® JIVE (not JIVE PRO/Kosmik) ESCs, as here the power consumption is calculated by MICROBEAST PLUS using the given current draw from the ESC.
  • Note there are some additional settings for telemetry available in the other menus. In GOVERNOR MENU you can use the signal divider and gear ratio adjustment to calculate the rotor head speed from the incoming motor speed. Most ESCs will send the electrical motor speed on the telemetry channel only, so you must divide the motor speed by the number of magnet pole pairs and by the main gear ratio of your helicopter, in order to display the rotor speed. See GOVERNOR MENU E and GOVERNOR MENU F for more details.


Connecting the telemetry sensor/ESC


Warning.png When using telemetry, the control line of the speed controller must be connected to pin [DI1], not [CH5]! The cable for the telemetry signal is plugged into [CH5] instead.




Hobbywing® Platinum (V4/V5)

Connect the control wire of your Hobbywing® ESC to port [DI1]. Connect the programming port of your Hobbywing® ESC to port [CH5] using a standard servo wire with male servo plugs on each end.

If needed you can connect the yellow wire for measuring the motor speed to the RPM input at MICROBEAST PLUS. The motor speed signal can be used for the internal governor function of MICROBEAST PLUS. For telemetry transmission it is not necessary as the data will be included in the telemtry signal!

  • Smaller Hobbywing® Platinum models (Platinum 60 and 80) do not measure current. Here displayed current and consumed capacity will stay "0.00". However, you can use the displayed battery voltage to estimate the maximum flight time of the model and to effectively prevent a deep discharge of the battery, i. e. by setting a low voltage alarm in your radio.
  • Hobbywing® Platinum V3 ESC don't supply any telemtry output. Anyhow, you can connect the motor speed cable as shown above to MICROBEAST PLUS. Then you can display motor speed/headspeed on your radio at least!



Kontronik JIVE

Older Kontronik® JIVE controllers come with a 3-pin debug connector that is normally used to program the motor controller by the use of a jumper wire. However, this connection also outputs some basic information about the motor controller and battery, which can be used for telemetry purpose.

Please note that this is not an official telemetry connection and the data may be inaccurate or not available at all. This depends heavily on the firmware of the ESC which we can't influence.



To connect MICROBEAST PLUS with your JIVE ESC you need a special type of wire. As shown below, the telemetry signal pin is the middle pin of the debug connector. The outer pin is common ground. On MICROBEAST PLUS side you must connect the signal wire to the upper pin of port [CH5] and the common ground to the lowest pin (=minus). You mustn't connect anything to the middle pin (=voltage) of port [CH5]!

Connect the control wire (MASTER port) of your KONTRONIK® ESC to port [DI1]. If needed you can connect the additional power output (SLAVE port) to the [SYS] port of MICROBEAST PLUS.

Warning.png Please be very careful when connecting your ESC with MICROBEAST PLUS. The voltage pins of [CH5] mustn't be connected with the debug port of your JIVE ESC. Make sure your wiring looks as shown above and make sure to connect the plugs correctly on each side. Do not interchange the sides of the wire. You can heavily damage your MICROBEAST PLUS or your ESC if not following these instructions properly!




Kontronik JIVE PRO/KOSMIK

The Kontronik® JIVE PRO/Kosmik controllers comes with a 5-pin connector that is normally used to program the motor controller by the use of a jumper wire. Since firmware version 1.10 (JIVE Pro)/4.12 (KOSMIK) Kontronik® added a generic telemetry data output to this connection. Please make sure your JIVE PRO/KOSMIK is updated to the latest version. On first generation KOSMIK series ESCs the telemetry port is the socket in the middle. On newer KOSMIK (Cool) ESCs you can choose, which port to use by software. Here select the generic Kontronik® telemtry protocol.

To connect MICROBEAST PLUS with your JIVE PRO/KOSMIK ESC you need a special type of wire. You can get a ready to use solution from Kontronik® - Ordernr. 9703 (TELEMETRY CABLE JR). As shown below, the telemetry signal pin is the middle pin of the 5-pin connector. The most inner pin is common ground on JIVE Pro ESCs. On KOSMIK the pin next to the "LED side" is common ground. It is highly recommended to use a multimeter and check polarity before connecting your ESC to MICROBEAST PLUS. Note that the pin on the opposite side carries +5V. Do not connect anything here!

On MICROBEAST PLUS side you must connect the signal wire to the upper pin of port [CH5] and the common ground to the lowest pin (=minus). You mustn't connect anything to the middle pin (=voltage) of port [CH5]!

Connect the control wire (MASTER port) of your KONTRONIK® ESC to port [DI1]. If needed you can connect the additional power output (SLAVE port) to the [SYS] port of MICROBEAST PLUS.

Warning.png Please be very careful when connecting your ESC with MICROBEAST PLUS. The voltage pins of [CH5] mustn't be connected with the telemetry port of your JIVE PRO/KOSMIK ESC. Make sure your wiring looks as shown above and make sure to connect the plugs correctly on each side. Do not interchange the sides of the wire. You can heavily damage your MICROBEAST PLUS or your ESC if not following these instructions properly!




Scorpion® Tribunus II

Connect the control wire (MASTER) of your Scorpion® ESC to port [DI1]. Connect the programming port (PC) of your Scorpion® ESC to port [CH5] using a standard servo wire with male servo plugs on each end.
