Power setup questions
Hi All
Just finishing up my Fury 55, and trying to decide on how to power everything. Things i have thought about.

Use a 4.8 NiMh thru switch to rx ,power CGY750 thru SBUS.
Use a LiFe direct to rx with two inputs no reg and again powering CGY750 thru SBUS.
Use LiPo thru Sahara to rx,SBUS to power CGY750.
Use a LiPo to Arizona using the leads to feed 6v to the CGY750 and powering the rx with SBUS from 750 to rx.
Or use a LiPo thru a Gryphon Extreme or Scott Gray Reactor X etc, that puts the cyclic servos on there own powerbuss type deal.

Anyways to many choices and not enough brain power ,so wanted to ask those with more experience than I what their thoughts would be.Just looking for a reliable system, but don't need overkill either as my flight skills atm only support mild sport flying:P
I had someone tell me using a 4.8 NiMh would work just fine for me,but I don't really know was kinda worried about feeding everything thru one servo plug to rx and SBUS to 750.

The CGY750 as well as the S-Bus like 8V, if your servos can handle it, and I think the Savox can then you should try and run the 8v.

I run a straight 2s system to everything.

For now I run the reactor on one Heli and the kiwi on another.u can use a small regulator for the tail servo if u use a lipo. Perfect regulator or western robotics makes a very simple tail step down. I use a thunder power 2s2p 3800 lipo.

The step-down cuts the voltage by 0.6 to 0.7 v so if you start with 8v it takes a few in series to get down to 5v. I prefer just to use a 3V 5V BEC for the tail. That way you have regulated voltage for the tail servo.

One of the main things i was curious about was how most were getting the power to the 750,only thru the sbus? I look at it like Futaba built it without a seperate battery input and i don't recall in the manual there being a warning or anything regarding a suggestion to do anything differently.

With a reg like the gryphon or reactor x, the leads for the 3 servos go from the reg into the CGY750 and then the RX is powered by the single S.Bus lead.

3 servos > regulator* > 3 ccpm channels > cgy750 > single s.bus > rx

* The only power is to the reg.

On my 600N the power is through the SBUS only, but on my 700N it is through the SBUS and i spliced in a "Y" on the throttle servo. This should cover any power shortages if there might be one.

My 600N has not seen any power shortage yet and i don't think there will be one. I am also running the 6.6 LiFe batteries with no regulator. I bought a HV tail servo so i do not need a step down for the tail. I am using a fail safe switch to turn the power on, but you can use a regulator if you want or just plug it strait into the receiver.

I am using an Align DS650 on the tail and running it at 8v. I have no regulators or step-downs of any sort on my models.

I have had the DS650's on 8v for almost a full year with 0 issues.

With a reg like the gryphon or reactor x, the leads for the 3 servos go back into the CGY750 and then the RX is powered by the single S.Bus lead.
Yea i understand how those work,and to be honest a setup like that would give me the most peace of mind,but like Mike had said he runs a direct 2s config and i was trying to get a feel for how those that are running direct lipo/life setup are doing it. All power into RX or one into RX and a Y or something to the 750.

You don't need to Y the 750, power is supplied to it via the S-Bus cable as the battery is plugged directly in to your RX.

Make sure that your entire system can handle a constant 8v, the Futaba RX & 750 will support 8v 100% but you must make sure that everything else in your system can handle it.

I have run my entire system on 8v successfully for some time but results may vary so please take the proper precautions when using any electronics that may not be rated for 8v.

Thanks for the info mike. I was going to use the 650 with my Vbar but went with a bls 251 insted. I have it steped down to 5v with a spektrum reg. Do you find the 650 to work as good as a bls 251 and last as long???Teambob00

The BLS251 is a very good servo and has been long proven. This servo shouldn't be run on 8v however.

I find that the 650 works very well on 8v but I am looking forward to the new HV tail servo coming soon from Futaba which has impressive specs and most importantly is 8v specific.

You are right Mike, you don't need it. But i am using it as a second way to power my electronics.

Correct...that single S bus lead / connector is only rated at 3 amps or so.

Kind of foolish not to run 2 power inputs to the 750, also not smart to run a standard servo on high voltage unless your sponsored and get free helis and parts.
