Lipo- TX/RX

[Papa]

WEll looks like the UBEC comes through once again. I will use it as a voltage regulator for the RX. I found this info on their web-sight.

"How can the UBEC be used in glow and gas powered applications? Since the UBEC is much more efficient than a linear regulator, it is a perfect match to use with lithium batteries to power a receiver. The UBEC runs at better than 90% efficiencies when run within specs. What does this mean? You will get significantly more usuable energy from the lithium battery pack to power your receiver than if you used a linear regulator. We only reccomend 3-cell packs in this application. the higher your input voltage....the more efficient your system will be. When using a 3-cell pack for your source power, the current draw from the battery pack will be almost half of what a 4-cell nicad pack would require. Here's an example:


A 3-cell lithium pack that is 840 mah in capacity would power your receiver and servos for about the same amount of time as a 1500 mah 4-cell nicad pack. If the radio system draws 4 amps a 5 volts (20 watts)...the 4-cell nicad pack will have to drain at 4 amps. However...the 3-cell lithium pack will only have to dump about 2 amps to deliver the 20 watts thru the UBEC.


Now, I am in the hunt for some quality lipo packs that will fit in the rx / box.
