I have always used and prefered Futaba radios for my hobby, however, when Futaba made available their "Digital Servos", they didn't emphasize at the time, the need for additional battery power needed to operate these hungry servos. None of the radio packages were including hi-amperage receiver batteries which were needed for these systems and it also seemed that the general model public were left to decide and figure out for themselves what batteries they were going to need and use. Even now if you visit the Futaba site, there are no hi-amperage receiver battery packs being made available.
I love my Futaba equipment but I think this was a rather disappointing aspect of a major RC equipment producing company. Surely being able to manufacture some of the finest RC equipment available, there was the unmistakable reality of the need for the necessary servo power requirement.
Sorry! but just had to get this off my chest!

The lot I got is not a lot, but I thank God a lot for the lot I got!

battery packs
I think there are so many choices of what size packs that people are going to use that they shouldn`t even put a battery in the radio set so they can keep the cost of the radio sets down.

I'm a little unclear as to why this is even an issue. Futaba clearly said all the way back in 2003 in this article: http://www.futaba-rc.com/servos/digitalservos.pdf which was written by the fine folks in the UK affectionately known as Rippy to the locals that digital servos have one disadvantage; Power consumption.

TMoore,
I have no desire to argue as to whether or not this is an issue!

Go to Futaba's website, look at available receiver battery packs now. It's ridiculous!
The fact that I can't purchase an appropriate receiver battery pack from a major manufacturer is unacceptable in my opinion.

Most people nowadays use LIPO's for their RX packs.
Not sure exactly why this is an issue.

However.....

If Nicd is still your flavor of choice, there are a large number of 3rd party companies out there that sell high capacity packs for I'm sure a lot less than the listed futaba packs.

The only time I used the RX pack that came with a radio was in a plank! Weight distribution, capacity and power requirements of various helis makes battery choice more critical than on planks. Specific selection is needed, not one size fits all.

The fact of whether or not there are a variety of other battery suppliers is not the issue at all. I am very well aware of the available batteries out there.
The issue is: Futaba as a company, did not and has not, provided a suitable receiver power supply for it's radio systems. Whether it be a regulated high voltage system or a 4.8 volt nimh or nicad. These are not available from Futaba. How could a manufacturer overlook and continue to overlook a very needed comodity?

Perhaps because they know that there are 3rd parties out there offering this already....at a far cheaper price than what they would.

It's also kinda like why most of the radio systems nowadays don't inlcude servos. You may have some, want something different than is package, want a combination, etc....
Same with RX batteries, the manufacturers can probably cut a few bucks off the costs by not including or just putting in a 'generic' type mah pack know that most modelers may already have in mind what they want in an RX battery so why make those guys "I don't know why they include this battery, I'll never use it, could've saved a few bucks if they wouldn't put it in the package".

OK! we buy our radio system without a receiver battery today.
Tomorrow we want the appropriate battery for our system. We go to the Futaba website to look for what is required and it doesn't exist? And we've found this information out from someone other than Futaba. Because they didn't make it available.
JR make available a 2700mah 4.8 nimh(which I'm currently using) why can't Futaba offer this?
Don't tell me that they're not able to make these available at competitive pricing with other companies! Certainly Futaba can purchase these from a supplier at considerably lower prices than anyone else.

It's not unacceptable. Futaba doesn't want the liability and I can't blame them. I haven't looked to a radio manufacturer for a power source in years.

An appropriate battery as you say will be determined by the input specs for that RX system regaurdless of the maker Some mfg use a battery of 4.8v to keep production cost down..

I'm with Mikerobe on this one. Futaba should market big batteries and regulators. Most of the aftermarket stuff is crap. My shinny new Arizona regulator looks like it was made by orphans in a basement. Both Futaba and JR/Spektrum have been using the "it was the power system, there's nothing wrong with our equipement" excuss for too long.

NiCD's are no longer being made. Any you get are old stock. Most of the Futaba packs are listed as discontinued at Tower.

And pay twice as much for the same battery.. no thank you. it will also push up the Kit price of the TX RX system to the point the company will loose money...I think some people want keep things brand specific. you can't see it when your flying. "isn't that what we are supposed to be doing anyway? Flying...

Futaba is not in the battery business.

Four Stroker,
Some have said that futaba may have wanted to keep the costs down but when you look at what these guys have invested in a regulated system. Cost is no longer a factor.
In fact if I were to comment about the cost of a receiver battery here on RR, someone would come down hard on me by saying "You shouldn't be skimping on $30.00-$50.00 dollars for a battery when you're flying a $5000.00 dollar heli".
So cost is not the issue!

The lot I got is not a lot, but I thank God a lot for the lot I got!

" flingin hands in the air"
Thunder power has batteries for eflite and the same battery without the eflite name is 30% less.
what we are saying is just use a battery that falls within the specs of your system voltage wise, if you have long flights ( camera ship ) get high capasity battery.

Just saying

Do the other Radio Manufacturers offer Regulator/Battery systems with their systems suitable for the use of high current draw digital servos?
