6V packs servo safe or not

[Steve & Cindy Kessler]

With my JR digital servos (8231) I had a bit of noise and hunting when using a freshly charged 6V NiMH pack (peak around 6.6v).  I then installed a 5.7V regulator.  No more top off voltage noise and jitters.  I have since switched from a 1650ma 6V NiMH to a 2200 4.8 NiMH pack.  Both batteries weigh the same.  I now have a lot more flying time before charging with almost no reduction in flight performance.  Just my $0.02 worth.

  Sure, it's safe with most of what's available now.  The current crop of JR servos and receivers are A-OK with 6V packs.  Most of the Hitecs I've looked at are OK and some Futabas as well.  Airtronics provides specs for 6V operation on some servos.

    So, is it safe to use an unregulated 6v pack with any quality receiver and servos? I have always used the Duralite regulator, but would like to get rid of it so I can quick charge directly through the switch without taking the canopy off and disconnecting the battery. 

    I was told that I could do that anyway depending on how it was wired, but I set it up exactly as the instruction say and am not able to quick charge through the jack.

    Thanks

      Have used lots of Airtronics 735/732's on 6v with no problems. Also, had 
      some 751's on six volts. Usually if the mfg specs the servo on 6v then it is 
      no problem using 6v. I believe Futaba was the only one who used to advise 
      against 6v use.
