throttlesafe RRP 49.95

Size 34 x 34 x21mm
Weight 31g including on-board rechargeable battery
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! ThrottleSafe 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)
Supplied with leads and mounting foams. Spares are available, see Spares and Accessories

Improving safety for electric powered models:
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
† 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).
