Servo recommendations for 6v.

[Icehawk]

I find this a bit hilarious for the 1212 -
"Operates directly on 7.4v without the need for an external BEC"
"Stall Current (at locked): 8200mA @6.0V, 10000mA @7.4V"

Uh, yeah you need a BEC here.

I use a No Brainer on my rig with a 2290 at 6v currently and I love it. I like the no muss no fuss nature but I also can't solder.

I'm really interested in something like this if I can set it at 6V. They talk about 3V, 3.3V, 5V, 9v, 12V, 24V. Then show output of 1V to 17V, which makes me think it should be infinitely adjustable with the pot. My cheap-ass BECs for 6V LED lights have tripled in price so interested to know if this would be a solid replacement? I'm a little different because I power my lights off a wire tap on the ESC battery connector thru a BEC and always have 6V to the lights, whether I am running 2s or 3s batteries.

Cheap old guy I am, I would order 1 to test but if I know I can set to 6V I'll order 5 or 10 at a pop as it looks like 5 - 8 weeks delivery from China.

Thanks.

Yup. There's a million variations, but that's one of them. You're not going to run a servo on one, but they're great for aux lights, or if you want to set your ESC to a voltage that's best for the servo, you can use one of these to drop that voltage to something safer for the receiver.

Also, depending on those "cheap ass BECs" that you're using for your lights, sometimes you can actually get 2 BECs out of 1. The little ones that come shrink wrapped often have 2 of these buck converters in parallel to raise the current output. For LEDs and other low current items, you can cut away the shrink wrap, and separate them, giving you 2 BECs.

Thanks Jim. I'll be ordering some of these. The BECs I use are dedicated to powering LED lights only, so these buck converters will work perfect for that.

Just want to say thanks to Jim for the "buck converter" info. I had heard of these but never actually got around to looking at them. Wasn't too sure about what to expect so blew the budget and ordered 3. Got them this week and wired 1 up for testing. Works exactly as described and I will be running all my LED lights off these instead of the "cheap" BECs I was using.

Glad I could help. Just make sure when you're adjusting the output voltage that you put some kind of load on them, because these cheap guys can output a higher voltage unloaded, then settle down as soon as they're loaded.

Thanks for the additional info Jim. I'll keep the voltage drop thing in mind when I actually set one up to use.
