Hi Guys,

I'm trying to use a 5.1V regulator from my Gyro. The Rx pack is a 6.6V Life pack. When I measure the output of the regulator i'm getting 6.3 V, shouldn't I be getting 5.1V ( I bought another one and it gives the same output ). I'm using a 9254 Futaba Rudder servo that operates on 4.8V.
The regulator is an Align brand,

pretty sure the Align 5.1 is just a diode step down giving you about .7v drop. It was designed to work with the Align BEC, which puts out 5.8 or 6.0v.
So it is not a true regulator, just a step down

with the A123 pack under load, it should be around 6.6v (all servos and receiver operational). Actual voltage to the 9254 with the step down will be around 5.9v, which is fine. The Futaba s9254 is rated for a 4 cell NiCD pack, which is about 5.8-6.0v off the charger.

Hi,

With all electronics in( excl tail servo) , together with the CGY 750 I'm getting 6.3V o/p from the CGY's rudder o/p. Is this safe.

6.3 volts with a 9254 WILL cause a failure of the servo.

It's a bit old school, but it works flawlessly. It's the Duralite 5.1 regulator, with the heavy duty switch. It's light weight, and works great.

I use mine to regulate a flight power 2s 7.4, 2100mah reduced down to 5.3 volts

+1 on the Duralite reg.

Also, the Arizona regs work very well, although physically larger than the Duralite. I also use the Hobby King really cheap regulators without problem - but not on helicopters.

But, your basic assumption is correct. If the regulator you are using is a 5.1V regulator, 5.1 volts is what the output voltage should be - with or without a load applied. If your regulator is outputting something other than that, then it is defective, misadjusted, not set up correctly (i.e input and output switched around), or for use with something other than what you think its for.

You will find many testimonials here about sucessfully running equipment beyond recommended voltages. I don't doubt those experiences are true. However, I don't do it as a matter of course for a large number of reasons. My point being - get a regulator that puts the proper voltage into your airborne system.

The older I get, the fewer things seem worth waiting in line for.

Go with the Perfect Regulators stepdown pro. It's a 5.3v stepdown but since it's actually a little regulator you can run whatever input voltage into it you want and still get 5.3v

I have been using the Perfect Reg. tail reg. for over a year now and it has worked great.

Why don't you get the Futaba PS-01 tail regulator (FUTM0960). 5 Volts out whatever you put in and whatever the load. They probably tested it with the 9254. I'm running one on a BLS254 on 5 cells. Have plans to go A123 soon.

As mentioned above , seems that the Align so called regulation just steps down the i/p V by 0.7 ie it is merely a diode being marketed as a Reg.
The Futaba is a good option but pricy, guess I will by a Aligh DS620 or 650 tail servo that can handle 4.8 to 6+ V

Go with something that is proven good. Duralite....

Duralite has been garbage for decades. But I haven't seen their newest stuff. Needed 2 volts headroom and didn't regulate until there was a load on it.

That review has the ring of truth. I originally tested it on my old 129 receiver and didn't notice any 72 MHz problems. Didn't range test it though. I never fly on 72 any more.

I am anticipating the 10A Futaba regulator for my very old stuff.

Graph of Futaba is pretty good. There is a big difference between real engineering and aftermarket engineering. SwitchGlo is a counter example - works great.
