ZTW 10A BEC / UBEC
ZTW 10A Universal Battery Eliminator Circuit (BEC/UBEC) - ZTW300200010
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 10 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 or 6 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 10A UBEC, nearly twice 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 10A UBEC uses a switching regulator, which will always provide a constant current throughout the duration of your flight.

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

ZTW 10A BEC/UBEC
First time I bought an ZTW and it seems to work as fine as the Castle Creations 10A BEC.
A super, duper, neat way to safeguard against ESC brownout or to make sure your servos have the power they need beyond the usual onboard ESC 5A BEC (which, in some stock models is just barely enough to handle the advertised load).
ZTW 10A BEC / UBEC review
I have been using thisZTW 10A BEC in five of my 8s Jets for about 4 years with no issues. I want to thank motion RC for carrying great products at an affordable price.
Great performance. A must for every high demand servo set up.
You get what you expected
I have this on all of plans with more than 5 servos. Works perfect.
Quality equipment at a great price.
I like the idea of having an external BEC in the case something goes wrong with the ESC. Two of the eighth that I got from Motion RC are already installed and they work as they said. Thanks Motion for such a good product.
