Esc q for you knowledgeable guy

[Ub Hauled]

I was wondering if disabling the internal BEC and running an Rx pack would allow one to run a 1s pack (3.7v) on a Hydra 120...

Jan, my 1.5 cents always disable the BEC circuitry and run a stand alone power source.

I am not familiar with the Hydras
IF the esc is suitable for power down to 3.7 or 1S then you are deffo good to go as long as you run an Rx pack.
Some speedies will not run on a single Li cell but if the hydra can then you are good.

As an aside, wtf are you running with a single cell ?? a personal cooling fan ??

[Ub Hauled]

LOL,
I have something that will run on 1s...
I guess I need to rephrase a bit...

Is the reason the Hydra is not rated for 1s it's internal BEC or is it something else?

The reason I thought about this is, I was sniffing around and found something they called a Booster module, it ups the voltage to the Rx so it can be fed it's required 4.8-6v to run itself and the servo(s)... so I thought, wait a sec, that's kinda what the external Rx pack does!
I would ask the folks over at CC but it takes them too long to answer me... =)

You could also run an external BEC to the receiver, cutting the red wire, thus disabling the onboard BEC in the controller.

What's the AMP rating on that thing? Am I truly going blind? I can't find it anywhere on that page.

I cant either, but I am downloading the PDF, maybe there they'll mention it

[Ub Hauled]

Hmmm.. not sure its rated for a lot.. they ask you to make sure to have "high flow connectors, 40-100amps"... I guess that's a lot for cars, lol

Nope. No can do Jan. The rx pack voltage does not power up the electronics that effect how the esc works. You need main battery power to do this. 1S in not enough volts to power the FET's to drive them. Andy might chime in since he is the expert. But I have already asked the very same question to Patrick at CC and the answer is no.

There are many 1s ESCs on the market. The BEcs in them (when supplied) step the voltage up for the Rx.
Anything from this,

to this.

I know Kinetic Racing sell some too.
All the best

That sux.... I have escs already and would very much like o use one I already own...
does anyone one know if THIS would work with the Hydra 120 or any Hydra LV for that matter?

[RaceMechaniX]

Jan,

What are you doing fooling around with 1S! Why don't you just try it? unplug the red wire, hook up the controller and see what happens............

LMAO, Tyler.. you got me there... that's what I'll do... it didn't even occur to me, LOL


will report om efforts...

[RaceMechaniX]

I have a feeling it will not work, but maybe worth a try. you will proably need to disable all LVC settings.
