Is anyone running Futaba S9206 servos at 6 volts? I noticed on the Futaba site they don't list a 6 volt torque. Does this mean you can't run them a 6 volts?

Thanks,
Dave

Thats what it means. They don't reccomend you run that one on 6 volts.

Thank for the info! It's interesting that the TOC guys could be running 4.8 volts on those monsters! I have the 2002 TOC video and most all the Futaba guys use S9206's. Plenty of torque for 4.8 volts though.

Dave,
I have a post on this site for about a month requesting the same info. When I purchased my 9206 servos last year, I was of the impression that they could be used for both 4.8 and 6.0 volt systems. My question is, "Has anyone had any experiences, good or bad, using these servos in a 6 volt system.
I am somewhat leary of flying the plane until I get some feedback. I have about $200 invested in the servos and I surely do not want to eat them.

Then use 4.8 volts packs.

I wish I could ask one of those TOC pilots what they were doing voltage wise. Almost all the TOC pilots using Futaba gear used S9206's in 2002 TOC. You can't tell me they run 4.8 volt systems! Not with Duralite batteries can they? What would be the purpose of regulating a 7+ volt battery down to 4.8? A buddy of mine said the Futaba rep told him they mean do not use 6 volts "unregulated" power. Anyone out there have any more input?

Lynx

Unregulated power from a 4.8 volt battery can go up to 6 volts. 6volt packs can be in the neighboorhood of 7.5 after charging. If you use a 7.2 volt pack and regulate it down to 6volts that sounds about right. But I think you'd need to ask more users what the safe max voltage they've ever used on their sero's was

I think I am going to put a thread in the IMAC forum later today.

Picked up a TFGS Corsair and it has the S9206 servos on the Ailerons. Overkill I know LOL. I am running A123 6.6v so I am assuming I need to ditch these for another servo that can work above 4.8v correct?

Thanks,
Pete

Dave, did you purchase these already? If so can you return them for something else, like S9155s?

If you can connect the servo to 6 v and it works it means the servo will work on 6V. It then depends on how you apply the servo. A servo will draw the necessary current to do its job and current is what burns out a servo. So it depends on how you are going to apply the servo. So if you are just going to fly an airplane and not do 3D with large control surfaces you are probably safe. If it were mine I would just go ahead and use them. Just make sure they dont get stalled anywhere.

If it were a 40 or 60 size sport plane I'd take a chance but this is a lg heavy warbird. After doing some more research I am putting HS 645's in place of the S9206's.

thing about digging up a 12 yr old thread is that the answer didn't change LOL.

The 9206 servos were good in their day but there are so many better choices these days. Even if they would work with 4.8V, which they will for awhile, they still had a frail, plastic first gear that was prone to strip if you bumped a surface.

Do you know of a metal gear servo that does not have a plastic first gear?

A 9206 servo has a coreless motor a Hitec 645 does not. The 9206 is faster and more precise than the 645

Yes, there are many servos that use a metal first gear. Savox and MKS just to mention a couple. Most of the high torque servos now have all metal gears. Hitec uses a composite first gear in many of their servos but it is quite strong by comparison to the first gear used in some of the early Futaba servos.

Yes too, the 9206 was a high quality servo but the 645 gets the job done and is a very popular and reliable warbird servo where smaller surfaces are used.

I am glad you mentioned that. I will make sure not to buy any of those servos.That plastic gear is there for a reason. In he days of 72 it could create noise if it were metal and you used a metal servo arm. Today that gear is constantly in motion even if the servo arm is not moving on tight deadband servo. Plastic wears better than metal.

Truckracer

I've certainly seen wear in metal servo gears but never on the first gear. Always on the output gearset. Frankly I liked the quiet operation of the plastic gears but with modern machining, metal ones are now as quiet or quieter than plastic and I'm talking mechanical noise here, not electrical. I would have no issue with any kind of servo gears as long as they are strong enough for the application and they don't wear out prematurely.
