Got them in my sport v2 with dfc head and ar7200bx. Amazing servos! Same servo as mks ds95 only cheaper! Fastest most powerful micro servo available! 3 crashes and no stripped gears.

60% of the time, it works every time!

5.5v at the moment from a YGE 45 ESC. Before I got that ESC I was running them from a CC 10amp BEC. The BEC in the stock align ESC wasn't enough and was causing brown outs. The BEC in my YGE is 3A continuous and 5A peak whereas the stock align ESC BEC is only rated to 3A max I think. These servos have bigger motors than standard micro servos so obviously draw more current.

Richardmid1 you got me thinking. I'm running the same servos without an external BEC and the stock align ESC. What happens during brown outs? I'm running a pretty high Head speed and it seems to bog a little during hard maneuvers. Could that be a brown out?

My setup:
450MX 14T
3S 2200mah 35C
90% and 95% Flat curve

If you are using spektrum it will stop the servos briefly until the voltage to the rx goes back up spectrum rx will brown out below 3v. A good test for your bec is to wiggle the collective on the bench as fast as you can, if you see the servos stutter you have had a brown out, the rx lights will also begin flashing.

I am actually using a yep! I just said yge because it's the same esc! Lol.

Yes 200hz. You will need to remove the middle red wire from the esc when using a separate bec.
