What is the maximum voltage that the new 5114 Rx can be operated with? A good 5 cell NiCad pack can get up to 7+ volts fresh off the charge. Can a 2 cell lithium (8.4 volts or so) be used without a regulator? Also what does Futaba recommend as the optimum voltage to operate this Rx at?

Same question for the other Futaba receivers?

And same question for Futaba servos?

You would not operate with more than a 5-cell NiCd or NiMH battery pack. Please be aware that some Futaba servos are limited to 4-cell NiCd or NiMH packs. There is no specification for other types of battery packs. Normally, you'd regulate at just under 6.0 VDC. If you have a system that can regulate at that voltage and provide enough current to the servos, you can use any battery pack that will provide the voltage and current. A 2-cell Lithium pack without regulator is definitely not recommended.

Bill,
I am flying the 6EX FAAST S3152 digital servos with a 5 cell NiMX. On a fresh charge my RX battery puts out 7.1V to 7.2V After 2 flights, the voltage is down to 6.7v and after 4-5 flights voltage is down to 6.3.I am not using a regulator, just a straight vanilla hook-up. The system is working perfectly. Need I have any concern about the 7 volts? Another thing, I heard is that NiMH batters do not develop a "memory" and do not need to be cycled. Is this true?
Thanks
JC
