Futaba 9253 max voltage ?
I have fromeco reg. and this servo ... on Futaba's page is only 4,8V.
Can I put 5,6V on this servo or is too much? The servo is for throttle(GV-1) ...

I ran the sister 9254 on 5 cells with a 6 volt maxium regalator for a few years no problem .

If you check the volatge of a 4.8 nicad you will find it will go up to 6 volts fully charged , if you check a 6 volt cell you will find it will be 7 volts fully charged .

You will be ok if you use that regulator

When the companies set the voltages for servos etc they set them on the basic battery knowing that they will go alot higher .

People then get confused

Running mine on 6V regulated, for 6 months now. No problem. The 9254, OTOH, could be smoked even if run at 4.8V. It's prone to failure.

Cool, what about 5.8V?

I'm thinking of using the align b6X reg and considering whether to bother with the 5.1V dropdown or not...........

I would use the cut down just on the servo if you have it , it will work fine with out it but it will work faster on the higher voltage and there for may fail early.

I will go with 5.6V just to be sure the arizona regulator is great
you can adjust from 5-6V

Thanks guys

Futaba doesn't recommend 6V, which Futaba interprets as a 5-cell NiCd pack. In fact, Futaba doesn't recommend using anything EXCEPT a NiCd pack with their servos. So by using a regulated system, you're already out of spec.

You have to take the recommendations in their proper context. A 5-cell NiCd pack (ie, "6V" will only output 6V when it's around half-depleted. When full, it outputs around 7.5V (or more, if it's a good pack). A 4-cell pack, OTOH, will output 6V (or more, if it's a good pack) when full, with load. In other words, we're using the servos at 6V, like it or not, even though we're following the Futaba spec of using a "4-cell NiCd" battery pack. If the "4.8V" servos couldn't take at least 6V, then nearly all servos would die very quickly indeed. Futaba will always say "4.8V only", since they want to cover their behinds.

A regulated system, OTOH, outputs a constant voltage, something that a NiCd/NiMh pack doesn't do. It won't go beyond 6V. Me and other people have used "4.8V" servos at 6V regulated with no problems (let's not count the notorious 9254 in this, it'll fail if you even breathe hard on it).

Firefox I agree 100% , problem is if futaba said they were ok to run on 6 volt then people would use them unregulated and put in 7.5.

But they should explain more in detail , the options of powering them.
