Description: 3-in-1 UBEC/CDI Kill Switch w/ Dual LED color Voltage Alarm
This 3-in-1 UBEC/CDI Kill Switch for Gas RC planes, allows you to safely and remotely kill your electronic ignition. It is Fiber Optically Coupled providing complete isolation between the ignition system and the radio system so there is NO interference. Simply plug this device into a spare receiver channel to give the pilot the ability to safely kill the engine anytime on the ground or in the air.  This is a must have safety device for any gas powered plane (most fields require a kill switch for gas planes). The 5 amp Universal Battery Elimination Circuit (UBEC) is a 'switch mode' DC regulator that takes the high voltage (6-13 volts) of the main battery pack and converts it to a consistent and safe 5.2 volts output to the CDI. This device also offers dual color LED alarm feature to signal when set voltage is detected. Voltage can be set to 4.8V or 6V and the LED will show Green or Red flashing or steady to signal the receiver voltage status.


  • Integrated CDI remote kill switch, allows pilot to kill engine anytime on the ground or in the air
  • Fiber Optic coupled input/output to the CDI provide complete isolation between the receiver power and CDI power to prevent high-frequency interference
  • UBEC feature allows direct connection to 2-3S lithium or A123 battery power supply
  • Real-time two-color LED displays receiver supply voltage (voltage 4.8V/6V can be set), warning the pilot if a low receiver voltage condition is detected preventing possible loss of control
  • The unique low-voltage alarm  will trigger when voltage drops below 4.2V or 5V for 3 seconds or more. Red LED light will flash and keep flashing until the batteries are replaced or charged

Technical Parameters:

  • CDI in: 6-13V
  • CDI out: 5.2V/0-5A
  • Weight: 15g
  • Volume: 35mm(L) x 17mm(W) x 8mm(H)

LiFe Batteries 2S

Our LiFe Batteries (also known as A123 Batteries) have huge advantages over most other options.

1) LiFe Batteries are lightweight - as light as Lipos
2) LiFes are safer than Lipos (do not combust easily like lipos)
3) LiFe Batteries supply a constant voltage (They stay right near 6volts from start to finish ensuring consistent flights)
4) Run Life batteries to your servos and ignition without regulators (For extra caution some people run a regulator to their ignition still)
5)Life's have a high Charging Capacity. Charge up to 5amps, allowing you to charge them up in MINUTES!

The 2100 or 3000 Mah can be used as a SINGLE battery system for 30cc planes. (we recommend spliting the lead and put 2 JR leads on, to run to the receiver and the other to ignition). You can also run a single 3000 Life Battery on a 50cc Plane.

The 1450mah LiFE Battery is a great option for those that want a separate battery for ignition and receiver (if you are running FM or hesitant to use a single battery system). The 1450mah Life is a great battery for the ignition for either a 30cc or 50cc sized plane

We recommend the following:
On the MXSR (2) 2100mah, or 1 3000mah placed on the mount box or front of the plane. It is a bigger plane and will do well with the extra voltage and weight.
Other 30cc planes - (1) 1450mah for ignition, (1) 2100mah for receiver or for a lighter set up
(1) 2100mah for both (split the wire to 2 leads) OR (2) 1450mah (one for ignition one for receiver).

50cc sized planes (1) 1450mah LiFe battery for ignition and (1) 3000mah LiFe battery for receiver or, for a lighter set up
(1) 1450mah for ignition, and (1) 2100 for receiver OR (1) 3000mah LiFe for both receiver and ignition
