Yes.

thanks man..do u knowwhy they wrote ni-cd use only??

they prob meant no use of 7.2v lipo, at least not without the 6v regulator.

thanks

the new brushless servos from futaba can or can't be used with lipo battery

Hmmmm I've never seen that. I am running mine in a car with a LiPo pack....

you have to use a voltage regulator with a lipo! 6v is 6v no matter the battery!

for nitro racing, where we plug the receiver battery direct into the reciever. so if you have a lipo receiver pack, the servo will be getting 8.4v-7volts, so it will be around 2 volts too high, thats why need a 6v regulator

for electric racing the lipo pack plugs into the ESC and the recevier plugs into the ESC, so its not an issue.

It does not matter what the battery source is (i.e. Li-po, Li-ion, NiCAD, NiMH, etc), only what the input voltage to the servo. Every car ESC has a built-in voltage regulator that takes the input voltage from the battery and regulates it to typically 6volts, which is the max most servos are rated to handle.

The reason that some Futaba servos came labelled "For NiCad use only" wasn't about excessive voltage. The reason was that in certain applications, people using NIMH receiver batteries were finding that certain servos pulled a lot of current and could drop the receiver batterie's voltage below the point that the receiver could operate and would cause glitching and lockouts.

It was most often seen in large airplanes with multiple servos operating.

I use nimh and lipo battery packs with all my Futaba servos. No problem, go for it.

Its all about the electrons!!! and electron flow, not sure if NiMH/NiCd will supply the same electron as a LiPO... might need an electron meter. I will test, document and report on my findings stand by for the results
