  • Audible LiPo Voltage Guard

    Audible LiPo Voltage Guard

    Lipo packs must not be discharged below approximately 3.0 Volts per cell. Even a single deep discharge may permanently damage your pack. The tiny Lipo Voltage Guard operates in parallel with your Electric Speed Controller. It will Start a High power piezo Sounder when your pack drops below a preprogrammed voltage threshold. The factory setting is for 3 cells , 3.0V per cell, with 'timed minimum hold'. The LiPo Voltage Guard may be easily reprogrammed to suit your own requirements with your transmitter/ receiver the supplied programming lead and your flight pack or power supply capable of any voltage between 5 and 45 volts.


    Microprocessor controlled, auto calibrating, 10-bit A/D converter with digital signal processing.

    Operating voltage: 5V - 45V
    Minimum threshold: 5V (2 cells, 2.5V / cell)
    Maximum threshold: 34V (10 cells, 3.4V / cell)
    Precision: 1% or better
    Current draw: 35mA during alarm state, <10mA otherwise
    Weight: 4g
    Size: 28mm x 20mm x10mm

  • CarbSmart


    CSM Carb Smart Adjusts the fuel mixture to maintain a steady cylinder head temperature Simplifies Mixture adjustment

    Helps to protect engine
    How It Works?
    Using a temperature sensor on the cylinder head CarbSmart leans or richens the fuel mixture in flight by means of a servo connected to the main needle of the carburettor.
    No Rx channel is required. The target temperature and the amount of adjustment are set by the user.

  • CSM BECSafe

    CSM BECSafe

    BEC failures can be very expensive.

    When faulty, BECs may place close to the full battery voltage onto the RC system burning out your receiver, servos and gyro - and leaving you with no control over the model! BECSafe protects against this as well as under-voltage and total power loss failures in BEC powered systems.  Protects RC system from over-voltage should BEC fail short-circuit - switches RC gear to your reserve battery to maintain control.
    Maintains RC supply by switching to your reserve battery should BEC voltage drop too low or fail completely.
    • Automatically checks BEC output before passing it to the RC system.
    • Automatically sets over-voltage and under-voltage trip points to suit BEC output.
    • BEC OK and BEC failure indicator LEDs
    • Size: 35 x 24 x 9mm
    • Weight: 11g
    • Optional reserve battery not included - typical requirement 600mAh NiMH. 4 or 5 cell depending on normal BEC voltage
    • Current capacity: 10 amps.
    • Low voltage loss (typically less than 0.1v with 5 amps load).
    • Dim: 35mm x 26mm x 9mm 12g

  • Throttle Safe

    Throttle Safe

    Improving safety for IC powered models
    Regulated LiPo supplies provide a constant voltage supply to your RC system at low weight. However, they do run the risk of sudden regulator failure leaving you with no control and, with no servo power, defeating the receiver's fail-safe system. With IC models this means you can have the throttle stuck wherever it was when the regulator failed! Throttle Safe protects against this eventuality by shutting the throttle servo using its on-board reserve battery should the regulator supply drop too low or fail completely.

    •   Throttle fail-safe even for total RC system power failure (e.g. regulator open circuit failure)
    •   In-flight low voltage warning by throttling back to idle for 1
    •   second every 30 seconds.*
    •   LED voltage indicator*
    •   Fail-safe in case of throttle signal loss with timed hold-at-idle
    •   followed by engine cut for persistent signal loss *
    •   Latched supply fault and signal loss indicators.
    •   Shuts throttle on normal radio turn off - inhibits engine starting with radio off.
      * (these features can be adjusted via optional PC interface)
