Denis Watkins Posted September 5, 2016 Share Posted September 5, 2016 No one wants to get involved Phil as none fits the bill Perhaps say, I have a 10 foot demon with retracts and flaps that needs sports servos that run on 6v That may help Quote Link to comment Share on other sites More sharing options...

Tim Cheal Posted September 5, 2016 Share Posted September 5, 2016 This may help if you haven't seen it before: **LINK** (I use JR 591 with a 5 cell NiMh and haven't had any problems, but I guess it depends). Tim Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 5, 2016 Share Posted September 5, 2016 please don't tell the JR 517s in my Dragon Lady with a 120 fs that they've been feeding of 6.6v LiFe packs for the last three or more years Quote Link to comment Share on other sites More sharing options...

Peter Jenkins Posted September 6, 2016 Share Posted September 6, 2016 I also run JR servos rated at 4.8 v on a 2 cell LiFe pack with 6.6 volts. However, with a 5 cell NiMh both my Spectrum (read JR for that servo) and genuine JR servos were unhappy. I'm told a fully charged 4 cell NiMH is a bit over 6 volts while a 5 cell NiMH is over 7 volts. So a LiFe at 6.6v seems OK. Alternatively, use a Powerbox switch which has a voltage regulator and can provide between 5.5 v and 6.1 v from a 2 cell LiPo. Expensive but does give you the benefit of almost constant voltage supply. Quote Link to comment Share on other sites More sharing options...

I guess the manufactures worked out the DS821 servos were too good, performance and flexibility at low cost. now things are a little more complicated. I guess that's progress for you?
