How much voltage can Z590 servos take?

From http://www.spektrumrc.com/DSM/FAQ.aspx#surfaceSystem

What is the voltage range of the SR3000 receiver and can I use a 2-cell Li-Po pack direct?
The receiver can handle up to 9.6 volts. The real limitations are the servos. Some servos are capable of operating at higher voltages while others are not. Check with the servo manufacturer that you're using for specific details.


I have a bunch of 7.2v 900mah airplane batteries sitting around, that would fit nicely as receiver packs. The receiver can take the voltage.....but what about the servos?

typically a servo will only take up to 6 volts.. anything over will probly smoke the circuit board.. but hey give it a try.. I use a Novalk voltage regulator when I run 2s 1900 lipo in my LST2 and 8ight.

I have a pile of used Z270 servo's (the cheap plastic geared ones) that I can sacrifice to test......I also have an Email into Horizon Hobby as well, if they might know.

+1 for the Novak voltage regulators. One of best products to come out in a while for high-voltage electric applications.

I have been running lipo as a reciever pack for a while now with no reg. and no prbs. local guys at the track have been running em direct for over a yr. with no prbs...I am running jr 9000T for my throttle and my steering..

7.4v ?

[blktransam]

yes...no regulator

[Y2KGTP]

yes...no regulator

JR 9000T digital ultra torque servo.
Specs:
Torque: 320 oz/in @ 6V
Speed: .15 sec/60 degrees @ 6V


wonder what it is at 7.4v? :D

Obviously these are nicer than Z590's.....but I got 4-5 laying around, and figured they might help torque and speed a bit with a little extra voltage.

The Hitec robot servos are rated for 7.4v... That would be a heck of a radio setup. Just run a lipo straight into the receiver without worrying about anything.
Just make sure not to over discharge those bad boys :p
As far as the z590 goes, I know a lot of people used to hype up their servos by doing something like this. It should work for at least short term, but don't expect your servo(s) to last as long that way.

I was more doing it for the convince of not hacking up airplane batteries (removing a cell) than running additional voltage, but thought it might help as well. I have 5-6 batteries total of these so I might just leave them alone...

If most RX run at 4.8-6V. I believe they'll work at theshold of 4.8V. That when they slow down,and the model shut off or become uncontrollable. Electric, servos may get jittery, or ESC may locked at slow speed or just shut off. Some people just use 7.8v pack for the motor, an extra 5 cell pack for the RX. This method you wont have trouble with, just the weight problem.

Thanks. I'm referring to just Nitro vehicles here, so just the receiver pack to contend with...

[blktransam]

I would go direct with the 7.4...JR servos have a 3 yr. warranty...

Kewl!! 5cell2/3A or the humpback will do for weight and time. 1400mah will do. It's up to yourself. Been useing 1400mah for a year now on-road nitro.

I've often wonder and wanted to try it, not that the regulator takes up alot of space...
