R617FS maximun voltage?
Can you use a 2 cell lipo with Futaba R617FS reciever? Can you use this reciever with the new 750 flybarless/gyro/govenor system that will be out soon?

Not sure about the voltage.
Yes, you can use it with the new CGY750, BUT it will work better and be easier to connect with the R6108SB receiver.

No problem running a 2S lipo on the R617FS receiver, It's the servos you need to worry about.

OK. I am wanting to use the new Futaba CGY750 flybarless unit with my R617FS reciever, Align 610/620 servos with a 2S lipo. It seems that would work assuming the new CGY 750 unit is ok with that voltage. Why would a different reciever be better with the CGY750?. Do I need more channels?

The CGY750 is designed for optimum use with the S.Bus receiver, R6108SB. If using that receiver the only connection made between the CGY750 and R6108SB is one connection. Very clean installation. If using electric model, there are two connections on the receiver (throttle). There are some features in the CGY750 that will only be activated with an S.Bus connection. They are not critical features, just some nice additions that you only get with the S.Bus. Same is true when using the GY701 with an S.Bus RX.

Here is a pic of the CGY-750 installation with R6108SB receiver in Kyle Stacy's electric model.

OK.thanks for the info. It looks like I will get this reciever and FBL unit. Will the Align 610/620 servos work with setup or do I need to buy different servos as well? Sorry for all the questions but this Sbus stuff is all new to me and not much info out there yet. Do I need the sbus controller ?

You do not need the S.Bus controller in almost all heli applications. That is needed when you have multiple servos on control surfaces such as in the giant scale applications. The servos should work fine, you may have to adjust for them in the controller, easy to do.
See these videos on S.Bus applications.

The sbus controller is required to activate F/F mixing on to GY701

Page 69 of "GY701. Advanced and adaptive operation":
(15) F/F mixing (S.Bus connection only)
default: off
This selects the F/F (Feed Forward) mixing active.
It helps the gyro operation by adding pitch
to rudder mixing prior of the gyro operation and
improves the gyro performance.
GY701 installs the pitch-> rudder mixing internally.
The swash signals are mixed in the swash
mode. The correct F/F mixing is achieved by
individual pitch signal is input in the GY701.
Separate the pitch signal in the transmitter, and input
this signal to the GY701. To do that, make the
programmable mixing as pitch-> AUX, and input
AUX signal to the GY701.
This function is only available by the S.Bus connection.
Invalid is displayed in PWM connection.
Pushing data+ or – key, the mode is changed.
May be the CGY750 also uses this function..
Sorry for my English...

That is correct, but this is an additional feature and is not required for model operation. The CY-701 will work just fine without an S.Bus RX. The CGY-750 does require an S.Bus RX to operate. There will be an adapter later that will allow the CGY-750 to be used with non S.Bus RX's and non Futaba radios.Team Synergy/Rail, Team Scorpion, YS Engines, VelTye
