External BEC or ESC Upgrade?

[allanon1965]

Thanks.

So, I guess the best option for me would be to power the servos with the HW BEC directly. I'll have to take a look at it once I have everything in front of me.

depends on what the servo you are running requires. I dont run a BEC on any servo under 300 oz of torque. I have found for my use, they are not needed. I do run the 10 amp castle creations BEC on any servo over 300 oz of torque and they feed the servo directly using the bypass adapter made by holmes hobbies. I have had zero issues following this formula"thumbsup"

I am a huge advocate for the CC BEC....and honestly we are talking about 20 bucks here. The moment I upgrade any rig from bone stock electronics, I add a CC BEC.

I'm a huge advocate of not spending money when I don't benefit from doing so. I had the Castle BEC on my Bomber when I first installed the Promodeler 470 servo. When I upgraded to a Mamba X ESC, I removed the Castle BEC and haven't missed it one bit. Because of that, when I put the Turnigy MG959v2 into my Gen7 I tried it without an external BEC before throwing more money at it. So far, it's worked flawlessly without one.

the gen7 doesn't need a BEC the servo is only 170oz

If you're using a high torque servo, adding accesories like lighting, winch, etc. Spend the $15-20 on a 10amp CC BEC. When you look at the total budget of your rig and mods, it's a small investment. Nothing worse than having your servo brown-out on the rocks!

Like I said in the text you quoted, I installed a Turnigy MG959v2 into my Gen7. That servo makes well over 300oz-in of torque.

If you're getting brown outs, then you absolutely should upgrade, but most folks are best off trying it as-is first to see how it works.

Merry Christmas guys,

I am a newb, but what about powering the aftermarket servos from these cheap Hobbywing UBECs https://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=hobbywing+UBEC&_sop=15. Does that allow the rest of the juice to power the other electronics, letting the servo operate at its full potential and not affecting the other electronics? I'll see how it is once I start setting up my electronics.

Will that work? Is that what these things are meant to do?

Thanks,

They are only 5/6V, 3A. Probably better than nothing but not much of an improvement over most built in BECs. They will certainly let your ESC power only the rx, lights and whatnot and thus have an easier life.

Originally they were meant for older electrics with ESCs that didn't have integrated BECs.
