What is the differences between this and X5 pro UBEC (product ID: X5UBEC)?
 v_max 5307 points
The only diff in description is X5 has statement : "(Less than 50mV peak to peak voltage * 2A)"
 Obamjur 70 points
So is it a good or bad thing ?
 v_max 5307 points
less p2p means less 'noise' on power... That's good.

Well I will set a glow engine (ASP S52A) airplane with 5 servos (4xMG-14 plus one HXT900) and a Turnigy Light System, all feeded by a Turnigy nano-tech 2s1700mAh20C LiFePo4 bat. My Rx is Tactic TR625 which has an input power limit of 6.0V. What is my best choice: to swap that LiFePo4 bat by a 2S LiPo and add this U5Pro UBEC or to swap that Rx by a Tactic TR825 which has 8.4V as input power limit keeping a LiFePo4 bat?

My best choice is keep up the Tactic TR625 and set up a Zippy compact 2S 2200mAh 25C LiPo bat with a YEP 20A SBEC regulated to output 6V. And be happy!

WARNING: we purchased 5 of these, all of them outputted 5.4V not 5V this messed up some of our equipment. ***********dronescan.co/images/voltage.jp

will this bec be enough for a plane with nine 9g servos?
 v_max 5307 points
Should be enough. 9G servo peak load current may reach 1amp but i hardly can imagine all your nine servos will be at peak load simultaniously.. 5amp should be enough.

I agree .... I use these for multiple servo setups. I also use in Glow / Gasoline models with 3S lipos to power Rx and CDi ignition.... 1 uBEC per service

Im trying to get an old rc car going again it uses brushed motor, analog 'esc' moved by a servo and a 7.3v ni cad battery which work my prob is I fried my rx when I plugged it in ( it uses the batt slot for power) will this work for powering it. It's over 20 years years old it's a maxxum ff by kyosho Thx

Purchased three of these for ignition voltage regulator duty in my large scale gas planes, when paired up with the turnigy 2100 Lipo receiver pack, you can run an engine all day versus the 4 cell NiMH packs. Working great in my planes, the 3A version works great too, but is a little longer and slightly heavier, but cost less. Next order, I will order more for spares for future projects.
