I want to run 6V on my new Gripen. The servos on my brake and retract switch are older but still good servos. I do I insure they can take 6V? It wouldn't be that big of a deal to cook them but I would rather not.
Yes I know I can go buy two new standard servos for cheap and then I would know for sure.

Most servo's that were manufactured in the past couple of years can handle 6 volts without a problem. But anything before that would be questionable due to the electronics that were used. Can you share what servo's you are talking about? That will help those reading this post to determine if they are capable or not.

Cheers,

I am using a Futaba s133 and a JR 537.

jr servos made in this century have no problem with 6 volts ( actually up to 6.7 with a top charge )....i cant say about anyone elses but i have heard a few no no s about some other manufactures


the big bird guys use regulators ( at 5.7v ) with 6v packs not because the servos cant take it...but because they are so good they can feel the loss of top charge and it affects their performance thus by regulating they can get a constant power flow from the beginning to the end of a flight

hope this helps

I have used 6V on just about any servo (even one of the few Futaba that are not cleared for 6V use), be it modern, digital, analog, or stone-old. Even the 30+-jear old Varioprop axial type servos will be up to the task....don't worry, i'm sure your JR will perform great without going up in flames . If you are really in dubt, solder a resistor in the power supply cord....That will get you down to whatever you want wile still being able to run a 6V systrem in your plane.

OK. Thanks

Gary,
When you state 6V do you mean you are using a 5 cell pack or a 5 cell pack with a 6V regulator. Reason I ask is without a regulator a 5 cell pack will provide more than 6V fully charged . Always best to regulate 5 cell packs.

6V unregulated works fine, too...never had problems or failures, and i power right on into the Graupner receiver.

I am using a 5 cell pack unregulated.

Same to me, always used unregulated 6V in planes with long extensions and lots of servos. never had a problem. In the expensive planes I use a second 6V battery conected in a Y -harness (with a second switch) in a channel slot for redundancy.
