bec isnt enough?

[4everyoung]

hey guys whats up,
I just put a bec on my wraith bc i switched to 3s and it is of course browning out and getting all sketched out when i crawl. Well, it isnt enough, i also have two led's that go through the bec as i have the adapter from holmes hobbies that gives me two other outlets to plug into. and then i also have a dig unit which requires the added servo.... why am i still getting glitching and browning out electronics?? if i dont get any advice im going to switch to the shv500 holmes servo so i can run power right off the battery and then use the bec for my dig and lights and see if i can actually enjoy my wraith while im dumping a shit ton of money into it lol.....

drew
thanks for any advice in advance

Can you please post a picture of the wiring?

And a volt meter reading.

[4everyoung]

what do you want to see as far as the wiring?
its a cluster f*** rats nest

[Solitaire]

Best thing for getting any advice is to list your electronics components and how you wired in the external BEC.

Well that could be your issue, have to know what is what to make it go correctly somewhere........

[snapon boy]

The bec should power your Servo fine if it's hooked up properly. You should not have any brown outs. Here is a picture of how the Holmes Hobbies adapter should plug in. I borrowed it from tsc crawlers. http://www.tcscrawlers.com/v/vspfile...rxbypass-2.jpg

yep i got ya, everything is plugged in right and working as far as i can tell..... thats the same adapter i have and if it wasnt hooked up i wouldn't have servo control for the steering or my lights working. all thats working but its like the bec isnt enough and it works like im not even running one, ill try to post a pic tonight

What do you have the bec set to ? Default is 5.1 v, castle link it

[snapon boy]

You may need to up your voltage, or if you did you may have gotten a bad bec it's possible

its w.e stock is i have no idea how to up it and what i would up it to

[4everyoung]

im going to take it all apart and start it from scratch to see if i had a loose connection or something like that

[snapon boy]

Ok stock cc bec is 5.5v is run mine at 7.4v. However all of my stuff is rated for that. Check your Servo and reciver and dig and see what they are rated for. The use the voltage that all items will agree on. You need a castle link to change the voltage or your local Hobby store will do it for you. Possible you friend has one.

That makes no sense.

What is your bec ?? Castle ?
Factory set to 6v you can raise it way up to servo voltage 8.4 using castle link

LEDs are not power hungry, my dig goes between the esc and motors , your servo operated dig won't take power except in use ( unless your end points are set over and servo is always running)

With what you are describing. Your bec isn't set (or fixed) at 5.1 v if you have the axial brushless.

If your wiring is a mess, tidy it up, but as you said everything works.

[4everyoung]

so my end points are set correctly and the servo isnt whining or over exzerting (spelling) itself, but i did some testing tonight everything is hooked up right and tight. i was out with the dog and since he likes to chase it around i ran it around with everything plugged in and it would work good for about 3 mins and then it would start fidgeting and browning out. i then unhooked the dig servo and i had no problem at all it wouldnt brown out at all or anything.....

once again i have the adapter from holmes hobbies with the spare outlet for the lights, so the the harness has the bec plugged in, the front servo plugged in, and the lights plugged in and then that is plugged into the reciever just for the control of the servo but no power. the esc is plugged into the reciever and the servo for the dig is plugged into the aux port, it is a stock servo from a scx kit which i know will need to be upgraded.... seems like i need two bec's one for the steering up front and one for the dig unit....?

i thought about uping the voltage on the bec but why would i need to do that?

i can post pics if it makes it easier for ppl to figure out what all im talking about but i feel like i made it clear

[mikemcE]

The reason you up the voltage is to prevent brown outs and glitching caused by the rig asking the bec for more voltage and amperage than it can supply. I run my servo direct from the bec, at 7.4v this is prime voltage for max torque and speed,receiver runs off 6 v, I run a split harness to get both

[mikemcE]

Rereading your last post the problem stopped when dig servo removed ....I suspect your esc has voltage in the bec set at 5.2 to 5.5.

What esc do you have

[honchojoe]

I don't get this thread. If you have your steering servo running off a bec (regardless of what the voltage is) it shouldn't be browning out. A brown out is when tbe servo draws more power than the escs built in bec can handle and causes the esc to drop voltage to the motor. So what is actually happening? Is the servo performing poorly? Or is the esc browning out? If you disconnect the dig servo does it start working fine?

Which ESC, BEC and servo?

Servo is stock tactic. Bec is castle. No idea about esc. Most likely stock ae5. If we can just clarify the behaviour we can work it out.
