Not looking for a USB port. Looking for a 5v power supply that will power some servos and have minimal EMI for the radios...

Thanks. I am really looking for a 5v supply to drive some servos. There are plenty of switching regulators out there but I am curious as to the effect on the radios...

Anyone have a recommendation on a 12VDC to 5VDC converter that isn't too noisy?

Sorry I asked...

Thanks, Bob.

I will just leave both attached...

I have an RV-10 that has a dedicated ground cable running from the aft battery to the firewall. This cable is connected to the firewall/panel (airframe) ground AND is connected near the battery, to t ...

Bob, so is there anything wrong with a grounding plan similar to the Z-15 for the Rv-10? It is simple enough to run that 2awg wire now, not so much later. For reference, the main 2awg wire running fr ...

If running a large wire ground isn't necessary, how does Z-15 fit in?

Just curious...

So is running a 2 AWG cable from the aft mounted batteries on an RV 10 to a firewall stud a bad plan? Would a basic airframe ground be the better option,i.e. ground the batteries at their aft mounted ...

Good story and you have a valid point, however, if no one ever tries to build a better mousetrap, progress would stagnate.

This is an ongoing discussion everywhere, not just these forums. There ar ...

As the OP, I wanted to ask Bob, specifically, a question. The title was meant to do just that. I do, however, agree with you that there is a good discussion goin on. Not sure if I can change the title ...

Very true.

You posted a reply in another thread that stated battery contactor failures in flight are exceedingly rare. Hypothetically, you could put a battery contactor in the feed line to a forwar ...

Sorry about the Zener symbol. The diagram was just sketched out give me something to look at...I never intended on posting it but I did so, as Bob asked...

Bob

This is just a simple drawing with reference to the Z-14.

The feeders to the "hot" busses are the ones in question. In the RV-10, the 3 contactors are located in the aft fuselage, ...

Bob

Thanks for the insight.

I am using electronic fuel injection and ignition. So the coil packs, a fuel pump p, and an ECU need to be on a buss powered by both batteries...and the c/b s need t ...

So what size wire did you run from the aft battery to the forward buss?

Bob

I am using the Z-14 for a template.

I have looked at the sketch of the aft mounted batteries, as I am building an RV-10 with an electrically dependent engine.

I would like to have the Mai ...

I do not see the Z-14 as dangerous as drawn for my EFII aircraft. The ECUs can be split between the busses, the fuel pumps can be split and the injector supply will be come from a buss powered by bot ...

Well, the alternator could get power from the battery buss...

Anyway, I am using a modified Z-14 for use with EFII systems. The essential buss will be powered from both batteries through a schottk ...
