Smokin' Mamba BEC?

[JasonInAugusta]

Eh...

A diode will allow current to flow in only one direction (forward biased). When you install the diode backwards (reverse biased) it can still allow current flow if you apply enough voltage. You'll usually get only milliamps of current through a reverse biased diode unless you buy a Zener, which is made to operate in reverse bias.

A cap, in that application, will charge and discharge due to the varying amounts of current that will be flowing through WTF1. It'd (in theory) block current flow through the servo leads but allow the effects of an AC signal (which would basically be variances in voltage due to fluctuations in current) to pass.

As the cap charges and discharges you'll end up seeing the cap discharge towards the positive lead on the RX through the RX...(it'd actually charge through the Mamba)

That cap will also discharge through the servo lead on the Mamba side, but that will be as a result of charging through the RX. :lol:

Just suck it up and use the RX pack. :lol:

I didnt think you can do that:shock: --jrh

I don't know if JRH's idea would work or not. It eliminates the negative side of WTF1, which is where the problem manifested itself, but with the extra voltage it could bleed through the signal side or just smoke something else.

The rig seems happy enough to carry the rx pack. Slobin, PM.

am i to late :lol:

the easy way without all the WTF´s and diodes
use the esc´s bec to power the receiver
plug only the signal wires from the servo´s into the receiver
and plug servo + and - wire to the 5th cell

Interesting idea. However, I've got a pair of receiver packs now, and with 8 cells aboard, the rig is happy to carry one.

Does this actually work??

I'm using the Kool Flight System's UBEC with my HH Revolver. Haven't had any problems at all and both the motor and servo are happy.
