Converting to Futaba 7008 Receiver from a JR Receiver
I hope this is in the right section.

I have a Heli that is set up with a JR Receiver and a Skookum 720BE. I am using a JR9503 Radio.

I am wanting to set up my Futaba 14SG on this Heli.

Do I simply remove the JR Receiver and install my Futaba 7008 Receiver via serial bus wire to the Skookum 720?

I don't know of any other changes that needs to take place on the 7008. Of course I know to set up the Skookum Software to realize the Futaba receiver.

I have other Heli's I am already using the Futaba radio on and I am wanting to convert everything to the Futaba.

Just making sure before I proceed.

Almost. Refer to the receiver instruction manual and make sure the receiver is placed in to correct mode. Then proceed with set up.

Ben, thanks for the reply. I should have included this in my OP. I will make sure it's in the right mode on the bench.

From what I can see is after verifying, just plug it in and start testing. My Skookum has all the settings ready to go. I will use one SBUS cable between the 7008 and the Skookum.

You will need to map the channels in your Function menu, to be the same as your JR transmitter.
You will also need to adjust the neutral or sub trim position as JR and Futaba have different centres.

And JR is positive shift whereas Futaba is negative...

Don't know if that is taken care of in the controller but just thought I would add this....
Been there, done that and old enough to know better.....

Yes, I am aware of this.

I will completely check the systems out before flight. I want to cover my tracks from every angle, so all comments are important and will be checked.

JR throttle channel is #1 Futaba #3 also you must reverse the Futaba throttle channel.
Expos are adjusted to a positive value for JR but a negative value for Futaba.
And Skookums do not like the Futaba receiver high speed mode.

Balsabasher, could you elaborate on your statement?

Can this be changed within the Radio or Receiver?

Dennis, this is copied from a PM I sent you back in 3/3/2017. My above reply was just a reminder.

"I am using the R7006SB receiver.
I went through the Skookum setup software on both controllers and the servos started acting funny. It was bad signals coming from the controllers.
What I determined, was that when a Futaba receiver is on the high speed mode, it and the Skookum did not play well together! But they did fine on the normal speed mode.
So the Futaba 12 channel mode is a high speed mode but the 14 channel mode is normal speed mode and did fine with the SK560.
Also I am using the S.Bus connection. Did not test on the S.Bus2 connection. I think the Skookum is not a S.Bus2 device.
So, if you was using the R7008SB receiver on the 12 channel (high speed) mode, that may have been part of your problems."

Thanks for reminding me. I will change the Skookum 720 back to 14 Channel Mode.

I had a lot going on a few months ago, so I am basically starting over.

Infact, I am going thru the complete software setup to insure it's correct. It doesn't take that much time, plus it's extra insurance.

Thanks Again, Dennis
