Just got back into crawling and I’m considering the fusion se for a new build. I was wondering how goodthe BEC is in these FOC systems. Should I still run an external BEC to power the high torque servo? I used to use castle ccbec to power my servos back when I was into crawling before.

Considering the fusion se 1800kv and running my Holmes TrailMaster BLS HV500 servo in an scx10.2

That servo is a direct-power servo:

Per Holmes Hobbies website:

"It is powered directly by a 2S to 4S LiPo battery via JST connection on your ESC's battery plug, eliminating the need for an external BEC!"

This type of servo doesn't use any sort of BEC - not the one on your ESC or a separate BEC - just connect directly to 2s to 4s LiPo battery, it'll work from the 6 volt to 16.8 volt range.

To make it even easier, Holmes sells in-line connectors for both Deans and XT60 battery connectors that have a JST power tap already connected.

Deans:

XT60:

Hope this helps!

actually it's not. It's the older version I have had for a few years but haven't used it yet.

I'm know how to wire it and have wired in a number of CCBEC in the past. I was just asking how good the bec is in the fusion. Wondered if anyone was using the bec and getting rx brownouts or other issues as a result from a weak bec. I have been out of crawling for a few years, so is everyone just direct wiring servo power to xt60/deans these days and not using external ccbec like castle offers anymore?

ah that makes sense



bec tec hasent changed much since you havent used it yet since you last used it the wiring will be the same as the last time you haven't used it yet



although some brands are bumping up the amps on there becs you would probably be happyer running a cc bec and saving the internal unit for lights shifters sounds systems phone chargers fpv power ports gps units speedometers and or a 12 volt jump starter pack lol

I think I will just wire in a ccbec I have and not stress the built in BEC on the 2 in 1 system.
thanks for the replies everyone. appreciate the feedback!
