Anyone using the Hobbywing QUICRun WP 1080 ESC?

Has anyone tried 4S on one of these yet...be handy to know. Thinking one of these with a 21T 550 Titan....

I tried 4s on mine the day I got it, it did not work. Nothing was harmed, and it's been running happily on 3s since then.

I posted about it here: http://www.rccrawler.com/forum/electronics/593178-brushed-motors-4s-6s.html#post5779364

Does anyone know how many actual amps their servo pulls at stall? The 20-30kg servos I’m looking at draw quite a bit more than the 3 amps that the 1080 supplies. Normal operating amp draw is much lower, but I just wonder about the potential for harm when the servo gets bogged down.

Going off this test, my Power HD LW-20MG can draw up to 4.3 amps which is obviously 1.3 amps over what the 1080's internal BEC can supply. I don't see it doing any harm as such but you might get brownouts. I recommend an external BEC like the Castle.

Edit: Looks like the 1080 can actually supply those kind of amps https://www.youtube.com/watch?v=NYqDSJaSX4A&feature=youtu.be
I'd still recommend an external BEC as I'm sure there's only so much the internal BEC in these cheap ESC's can handle when you're actually out driving

Thanks for the reply. Looking at HiTec 25+kg servos, I’ll probably go ahead and get a BEC. I’m running a cheap Amazon 20kg servo now but want to replace it soon because it doesn’t center.
