Default could you make 7.4 volt servo's

anything in the works
just seems like the way to go
no regulators
less weight
less likely to drop below the spectrum voltage limit
I would love to just use a lipo battery without all the other hastles
please consider it
I am just letting you know what I realy want as a consumer
thank you for your time

I've run JR servos on a Li Ion pack. The servos jitter a little bit from the hot voltage, but they will work. I have not flown my jets under this condition, just run my own tests.

I can't speak to future products, but I'll pass along the suggestion.

They have some coming very soon. They will be branded Spektrum servos. That is from the "horse's mouth." Paul Beard. Before the end of the year. No reg needed for a 2S lithium. Alan Szabo is running them now in his Avant heli and has all year. I have seen them.

Norman, the information you posted is not correct, there are no plans for Spektrum servos like you mentioned at this time.

rumors on the heli sites is that lots of folks are running the 8717's on unregulated 2S

Has HH or JR done any testing with these servos at 8V? Any word on support of this configuration?

Alan Szabo has done it since day one with them and so do all the heli guys. I have three of them going in a 90 heli and a Spektrum RX is designed to operate off of up to 9v just fine. The 8717 works fine at 8 volts. They are INSANE fast and powerful at that speed. I asked Alan about his and he has been running them off of 8 volts since beginning of the year almost.

Servos that would operate on unregulated 2S Lipo's would be GREAT!

Think of the capacity, the speed, the torque, and the light weight!

And of the better efficiency because losses are represented by I^2
