Hi,

For the following servos:

9150, 9151, and 9206 Futaba recommends to be operated under 4.8v voltage. I have a Jaccio 5.2v voltage regulator could I use it with the previous servos?

Whats is your opinion/experience?

Thanks in advance,

Nikos

Hi Nickolas

I had the same question a couple of months ago, so I posted on the Futaba support forum and got the following reply:

The maximum regulated voltage should not exceed around 5.5 to 5.7Volts

I have been using 5.5V since with no problem. So you should be alright using 5.2V

I think the 4.8v refers to a 4 cell nicad/nimh that would be around the 5.5-5.7 volt when fully charged, discharged it will be 4.8 volt.

So the regulator is is bringing the lipo down to a fully charged 4 cell level.

Thanks for the answers.

I have not much experience with Futaba servos that's why I asked.

I have used the jaccio regulator,,, it works great with 9151's.

Nikos,

I personally run all of the Futaba 4.8 only servos at 6.1V and have had no problems. I even run the 9254 heli servo for my elevator and have had zero problems over the last few years. I've run 9151's as well...no problems,

Arch

same here I run 6.0 volts on all Futaba servos, no problems

When you say you run 6volts do you mean a 5cell nicad/nimh pack or a battery pack (lipo etc) regulated at 6volts?

Because a 5cell pack is going to be 7.5-8.0v at full charge.

Off topic but I did have the same question to Graupner/JR.

There answerer was that 4.8 V servo from Graupner/JR are specified to max 6,3 V. I have a Powerbox regulator that give 5,9 +- 0,1 V or max value at 6 V. That is OK for 4,8 V servo from Graupner/JR.

Sorry, I am running a FlightPower 800 2s rx pack and the Smart-Fly 6.0v Pattern regulator

Thanks for the answers.

An irrelevant question, have you encountered any incompatibilities or strange servo behaviour when using Futaba servos with JR receivers?

Looking forward to replies,
Nikos
