I have a Talon 90 on my Logo 550sx with JR NX8925 servos. At the moment I have the BEC set at 6v, the servos can handle 8v but im worried the single BEC lead won't handle the extra current on the higher voltage. Anyone running a similar combo on 8v?

Current draw will go down as voltage goes up. I move to 8 volts.

It's the other way round with servos fella. You can't change the motor or gearing in a servo so when you start driving it harder with high voltage the current draw goes up.

Well thats news to me maybe things have changed over there in the land of TEA TIME the past 25 years in the aerospace industry as a electrical/avionics tech. and after performing hundreds of electrical load analysis on AC and DC systems I agree with Kevin Dalrymple and I am sure a gentleman by the name of Tesla also agrees I believe he has several published papers on the subject as I said maybe things have changed NOT

V = R * I

P = I^2 * R = V^2 / R = V * I

"the single BEC lead "

On that ESC....can't tell from the CC pics....can you get to where the single BEC lead is attached to the PCB?

Perhaps you can open the mechanical package.....

If you can, you can add another BEC lead by simply soldering another one to the stock lead right at its junction on the PCB.

"Creative soldering"....for a dual lead SBEC....

Just use an iron that has a "grounded tip"....

P.S.....you're using the PCB junction(solder pad) as a "mini power bus"...for extra current capacity than that of a single lead.

Imo, CC should have done that in the first place....because of the ease of doing it.....

Ohm's law isn't an "except servos" sorta thing. It is after all a law.

Some politicians want to repeal that law....

Ha I'm fully aware of ohms law but we are talking about servos running at different voltages so have another think!

Maybe you could explain why when you run a 12s heli on a single 6s pack the current draw is almost halved?

Let me know when your on the right page.

I don't know what to say about that
except the books over there are different than the books over here. Sit down have a cup of tea and think about what you said you will then realize I am spot on mate.
