Overview
ZTW 18A Universal Battery Eliminator Circuit (BEC/UBEC) - ZTW300300010
The ZTW Universal Battery Eliminator Circuit or UBEC is the easiest and least expensive way to protect your plane from an ESC failure or "brown out" condition. The ZTW UBEC is a crucial device if your ESC does not have a battery eliminator circuit or if the current draw of your receiver, servos, retracts, and lights exceeds the current capacity of your ESC's internal BEC. The ZTW UBEC installs easily between your aircraft's battery and receiver (see diagram below). ZTWs 18 Amp UBEC offers a cost effective solution to power your critical circuits and protect your investment.
What is a UBEC? A UBEC or “Universal Battery Elimination Circuit” is an external electronic circuit that taps power from your aircraft's battery pack and regulates the voltage down to the necessary 5 to 8 volts for the receiver, servos, lights and retracts. A UBEC does not replace the speed controller, it replaces the BEC (Battery Elimination Circuit) or SBEC (Switching Battery Elimination Circuit) function embedded in the electronic speed controller, with voltage control capabilities and more available current.
Why do I need a UBEC? - A UBEC is recommended for the following reasons:
- More available current to critical flight control components: if you are using a large number of servos, generally more than four, or you are using high current draw servos, you will need a UBEC to supply the necessary current to the servos for reliable operation.
- Redundancy: in the event of an ESC failure due to overheating or any other condition the internal BEC or SBEC in the ESC will usually fail as well. If your internal BEC fails you will have NO control of your airplane and likely crash. If you utilize a UBEC and the ESC fails, you will still have full control of your airplane's control surfaces and landing gear, allowing you to perform a "dead stick landing" and likely save your model.
- Reduced chances of "brown outs": if you are coming in for a landing and put retracts and flaps down at the same time while steering the ailerons, rudder, and elevator (plus the lights are on), you have the possibility of too little current available for your aircraft; this is referred to as a "brown out." Something as simple as a stuck retract can consume a significant amount of current causing brown outs or other electronic problems. Having a 18A UBEC, nearly triple the amount of current typically found in an ECS's internal BEC, ensures you will have sufficient power for all your electronics.
- Superior performance compared to Linear BECs: Many ESCs use a linear BEC as opposed to a switched BEC. A linear BEC provides less power as the battery pack is used up during flight, therefore, the probability of a brown out and subsequent loss of control goes up dramatically the longer you fly. By comparison, the ZTW 18A UBEC uses a switching regulator, which will always provide a constant current throughout the duration of your flight.
Features:
- Provides ultimate safety in the event of an ESC failure, allowing you to retain full control of flight surfaces and landing gear
- Provides a powerful 18 amps of peak current for large number of servos or high current power draw servos
- Decreases the electromagnetic interference for a secure receiver connection
- Blue LED light display to show the BEC is active and working properly
- Battery polarity reversal protection

UBEC Wiring Diagram
Please note, you must remove the red wire of the ESC's SBEC to the receiver before connecting the BEC. Alternatively you can install a battery eliminator cable which automatically eliminates the red wire.

At first I couldn't find a one that would do the job (at least not for any reasonable price), but I was glad that I found this ZTW UBEC at Motion RC. The UBEC is small, easy to install, and it can provide more power than my set up requires. It's always good to have redundancy, so this little gadget fits the bill perfectly. Till now it works as it should, so I can recommend it. Please note: In the photo, the voltage indicated on the displays is 0.2 volts under the true value measured by a multimeter. So the ZTW UBEC does deliver the full 8 volts.

I use both power inputs connected to my RX as per advice from Horizon Hobby. I like the ability to set my RX voltage to be the same as when I had the LIFE battery powering the RX in the gas version of my plane. I set it to 6.5 Volts and the telemetry reads out 6.5 volts. Perfect. I likely have close to a hundred flights on my first conversion (Balsa USA Cub) with no issues at all.
