More I think about it I'm not liking the CGY-750 for electric. If in the future I decide to fly nitro again, then it will be the ticket!

The fact that Vbar is offering the ability to use brushless phase sensors to control the gov on electrics is a HUGE plus in my book.

I really like that idea. Those are much easier and simple than magnets and sensors.

I wonder if you could just use an Eagletree sensor and it would work. If not perhaps a simple interface would solve the problem.

I think that Futaba is not into electric as much as the rest of the world. EP has really taken off on the last year with the availability of very high quality cheap LiPo batteries from China. Futaba needs to stay up on market trends.

You guys might want to read Mrmel review on using Vbar on electrics with more common ESC.

Read it, there will be many that can and will use phase sensors, it's simple application.

I am certain others will be able to develop such integration, it may require however some external devices past a RDU sensor is all.
I am certain Futaba will get there as well, or may have solutions in works now that can not be discussed, who knows, Futaba makes good stuff and there is no denying that.

Currently though only one I know doing the RDU sensors is Vbar "at todays date"

And for the record I love Futaba stuff, so even I for my own interest will try this one out to, cause I like to try out all that is out there to know what is real and what is not, take care.

I think it's very important to remember that this is Futaba's first shot at a fbl system and it's already as good as the best.

It's funny that a few months ago people were more concerned with how a system flew far and beyond anything else and rightfully so.

I'm actually surprised to hear a few people not willing to give the cgy750 a try simply because of the gov, especially since most are already running their ESC's in gov mode. Essentially it comes down to one or the other but you will have both options available.

The cgy750 will undoubtedly evolve and with the folks at Futaba working diligently on so many new things as of late there is no doubt that they will continue to aim high and please.

Is it for sale already? Were you on the 5.1.5 Beta team for vbar as well?

I talked to Jason Krause this weekend and he said that he typically doesn't like FBL, but liked the Futaba FBL. He has tested it and had good things to say about it.

I do hope that this doesn't turn into the typical V-bar against the world thread.

Please don't turn this thread into a pissing match, this type of standoffish attitude really sours threads.

Having flown every other fbl on the market, the cgy750 is what works best for me.

The 5.1.5 software hasn't been released yet so it's not comparable at this time for me.

The reason I asked is I'm trying to put together my first electric heli. Choosing the right ESC is very important to me and just wanted to hear the feedback on the governor feature in this configuration.

I already have 2 of the GY750's on pre-order and know it's going to be a great FBL system.

Thanks,
Chris

Hi Chris, it's a valid question so no worries.

I think you will find as Ben explained the Gov function will on the CGY750 will work very well. You may need a bit more setup time for E models but you only do it once.

You will also have your ESC which will more than likely be a Castle, another fine gov option.

No mater what mike its already turned into a p contest. Now i'm not sure how the Phase sensor work. But a wild guess: you get a pulse per pole. So for futaba to use this all they would need to do is up there sampling freq and divide the pulse count by number of polls to get rpm (and gear ratio stuff). But if the sensor gives you an encode value or use a protcal that it might be an issue.To me does not sound like a huge deal. Anyways I still have 4 units pre order and going to sell my full size vbar as soon as i get my hands on them =).

750 governor use clarification

It was brought to my attention by the 750's designer that this product DOES support 1:1 gear ratio for electric models. You CAN effectively place just one magnet in the maingear and read off of that. This will make installation and execution far simpler. I apologize for the confusion. We had received draft manuals in several parts, and I had not noticed that change in the governor software verbage.

I'll fish back through my earlier posts and correct them as well.

That just does not seem like a good idea. Placing a magnet onto a maingear or drilling into one to place the magnet??? Any way to just use a sensor in the works???

One small hole in the gear or auto hub for the magnet.

At least one other mfg's product has used that technique for years in both 3D and F3C application with good results. It works fine and is no more complex than putting a magnet in a cooling fan of a glow installation. I'm not aware of a direct motor sensor at this time.

Many of us did this for years with the old eMultiGov product. I simply epoxy a magnet on my Align 600 main gear and it never moved. I did not drill any holes into the main gear, and it worked perfectly. On most main gears there is a little corner you can put the magnet in that will help keep it glued in place.
Any way to just use a sensor in the works???
Not that is publicly announced at least, maybe in the future.

EDIT: Found a picture of what I'm talking about in the eMultiGov manual. They have you glue the magnet to the tail drive gear instead of the main gear. Not sure if it makes a difference.

How about a phase sensor like what's used for the vbar gov for electric?

That is good news. Now I can use the same setup as my eMultiGov.

I have one on order and can’t wait to try it out.

This has already been covered several times. The Futaba CGY-750 does not have the ability to interface with electric sensors like the Hyperion brushless phase sensor currently. In the future, who knows, anything is possible.

However I will say this, Futaba traditionally has not supported third party sensors, think back to the original GV-1 and the GY-701. If they do come out with a electric sensor support you can bet it will be a Futaba proprietary sensor and not a third party one supported like the Vbar.

Chris,

I configured my SDX with a collar/single magnet off the counter shaft. It set up very, very well. I'll post some pics shortly and will test fly it this weekednd.
