Ultimate BEC 5 Volt StandardThe Ultimate BEC eliminates the need for a separate battery pack to power your Rx and servos.
Use the Ultimate BEC when:
Your cell count and / or number of servos exceed your speed control's ratings.
Simple to install! All you do is solder the UBEC input leads onto your speed control power input leads.
Plug the UBEC into your RX where you would plug in your Rx battery. - OR - Plug the UBEC into a standard on/off switch harness.
Make sure you disable your speed control's BEC by cutting (or removing the pin from the connector shell) the red wire (Castle and most other brands)that's running to your throttle channel from the BEC.
What makes the Ultimate BEC different from the BEC in my speed controls? Speed controls use a linear voltage regulator to reduce your battery pack voltage to 5 volts. The challenge with this kind of system is that it is limited by the input voltage and output current. Each ESC has a limit as to the amount of watts of heat it can dissipate. The Ultimate BEC is a switching power supply where input voltage and output current are independent of each other.
Will the Ultimate BEC cause any radio interference? Absolutely not. As a matter of a fact, most speed controls put out way more "noise" than the UBEC. The UBEC has been designed on a custom copper flooded board and utilizes a shielded coil to eliminate any "noise". Most importantly, any "noise" that radiates from the UBEC is not relevant to the bands within our radio systems.
How do you keep your battery from running too low? Most speed controls have a low voltage cutoff feature to keep you from running down your battery too low. Most low voltage cutoff features cut power to your motor between 4.7 to 5.5 volts. The UBEC will goes into bypass mode at 5.5 volts. Thus, your Rx will still get power from your battery.
How many servos can I run on the UBEC? Servo currents vary by brand and type. However, 8-10 servos should be no problem. The main thing to remember is that the UBEC is rated for 3 amps continuous / 5 amps peak.
