Is there a simple way to regulate the 5.6V out of my Duralite regulator down to 5.0 for just the gyro?

There is no need to drop the voltage for the gyro, I have been running the same 5.6v duralite reg for over a year now with no problems, and I "think" the higher voltage problem is with the servo not the gyro, 5.6 volts is fine- a fully charged 4.8v Nicd is near that voltage.

By gyro I meant servo and gyro. The gyro powers the servo at 5.6V too then right? What servo are you running?

The servo should take up to 6 volts but it needs to be regulated 6v, the unregulated 6 v packs running at a full charge are what can cause problems.

That being said I run 5.1 duralite regs, plenty of consistent power and no worries with servos or gyro.

You can probably get away with 5.6v on the gyro/servo, but I think it's pushing it.

Even though the fully charged 4 cell nicad or NiMH pack approaches that voltage open circuit, it drops under any load.

I like the Fromeco Arizona regulator system. Gives you the best of both worlds, 5 volts to the gyro/servo and adjustable to over 6 volts on the rest of the system.

I have an Arizona on my other heli but this one came with the Duralite single-output regulator. I was hoping maybe there was some sort of smaller inline regulator I could put on the input to the gyro to regulate the 5.6V down to 5V.

Have you checked your Duralite to see what it's actually putting out under different loads?

No, but I read that other thread and plan to do that.

break out the servo red wire ?

what if you run dual regulators ?

just break out the gyro servo red wire and run 6 volts to it.

use a 5 volt reg for the gyro.

the gyro just passes the + amd - right through to the servo and the gyro only controls the white wire.

correct me if I'm wrong here because I have not seen a schematic of the inner gyro workings.

you should aslo be able to break out the black AND red wire from the servo for direct regulator hook up and just leave the white in the gyro connector....

just an idea of how to get the awesome response of 6 volts to the servo and have proper reg for the gyro.

a dual output regulator would be ideal

Yes maybe I'll buy another Arizona. For now I think I'll try just dropping .6V by throwing a diode in each of the red wires to the gyro. Unless of course the regulator drops the necessary voltage all by itself under load.
