Frequently Asked Questions:

Q1. What is a UBEC, and why would I need an external one like this HOBBYWING 3A UBEC?

Ans. A UBEC (Universal Battery Eliminator Circuit) is a voltage regulator that steps down your main flight battery's higher voltage to a lower, stable voltage (e.g., 5V or 6V) required by your RC receiver, servos, and flight controller. You might need an external UBEC if your ESC is an "OPTO" type (no built-in BEC), or if your existing ESC's BEC cannot supply enough current for all your onboard electronics, preventing brownouts.

Q2. How do I select between 5V and 6V output on this HOBBYWING UBEC?

Ans. The HOBBYWING UBEC 3A typically has a small jumper or a tiny switch that allows you to select between 5V and 6V output. Refer to the included user manual for the exact method, but it usually involves placing or removing a jumper cap on specific pins, or toggling a small switch on the UBEC board itself.

Q3. Can I use this HOBBYWING UBEC to power my FPV camera and video transmitter (VTX)?

Ans. Yes, the HOBBYWING UBEC 3A can be used to power FPV cameras and video transmitters, provided their combined current draw does not exceed the UBEC's continuous 3A output. The selectable 5V/6V output is compatible with many FPV components. Always check the power requirements of your specific camera and VTX to ensure they are within the UBEC's capabilities.
