Wiring:

R617FS  Naza
1       A
2       E
3       U
4       R
5       T
6       X1
7       --

In the transmitter, start with a new ACRO profile. Then make the following changes in the receiver:

• Reverse channels 1 and 4.
• in the PARAMETER menu, assign channel 7 to SW G.
• Go to P-MIX1. Make the master channel 3, slave channel 5. Rates are +100%, +100%. Leave offset at default (middle).
• Go to P-MIX2. Make the master Ch3 and slave ch 3. Make both rates -100% with default offset.
• Plug in flight battery, USB and start Assist software.
• Go to P-MIX3. Set master to Ch. 7 and slave to Ch. 3. Adjust one of the rates so that Failsafe shows in the software.
• Exit the P-MIX3 and go to the FAILSAFE menu. Set the position.
• Go back to the P-MIX3 settings and adjust for GPS/Atti/Manual. My rates are -60% and -60% (so that GPS is the furthest position away from me)
• Adjust endpoints of channel 5 to about 133%,133%. Optionally, you can calibrate in the assist software to get full throttle throws.
• Exit receiver config. Confirm F/S works by powering off receiver.

That's it. I hope there are some who find this useful!

Thank you so much for posting this!! it is exactly what I wanted to achieve with mine, I have exactly the same set-up but couldn't figure it all out. Still took a lot of work as my settings were slightly different to yours some some crazy reason. But now pot works gimbal lost signal RTH runs as does RTH on the 3 way switch

Thanks again

INteresting thread. I had a 617 on my Hexa 550 in regular configuration. This setup by Locks worked for everything but the IOC. I am using a Futaba 14Sg and while all the settings worked. the IOC has a problem that it doesn't shut off. It is either in Course Lock or Home Lock. I can't seem to adjust either with end points or sub trim to get the 3 position switch to turn IOC off. any suggestions?

With Locks setup, can we assign the switch D for gimbal tilt control or that switch is in use? Sorry to ask im totally confuse/noob on this thing.

[akecema]

wanna ask

how to set knob VR as gimbal controller?

[cmfhegs]

Hi -
This is based upon FloridaBear's directions on how to get everything setup so that the knob may be used with the gimbal.

Everything worked, but..... now when I take off it does so quite slowly, as soon as I take my thumb off of the throttle, it starts to descend very rapidly.

I've tried gains both on the transmitter and within the assistant software. thus far, nothing has worked.

any suggestions?

thanks!!

Hello locks,
I will use my FF-7 with the Sky Hero Little Spider and the NAZA M V2+GPS with an R617 FS
your guide ist very good but I am a beginner with copters.
I only fly Scale-modells.
But my greatest Problem is: I need the Tx with Mode 1.

What must I change in your guide when I want to use my Tx

Best regards Joachim

[JoJoS]

Hi,
in stead of the R617FS I will perhaps use the R6308SBT-2,4 GHz FASST-Telemetrie
Can you help me?

Hello!

I'm a bit of a late bloomer and finally got a naza lite / able to flash to m v2 if needed.

I happen to have a futaba T7C tx and i was trying to follow the instructions, but at this part and after i found myself unable to follow the instructions:

7- The Tx Advanced Menu “HOV-THR”, Set HOV-THR to INH

8- The Tx Advanced Menu “HOV-PIT”, Set HOV-THR to INH

9- The Tx Advanced Menu “GYRO”, Set GYRO to INH (more on this later)



Where exactly is the advanced menu? i couldn't locate these settings on my receiver even after changing the settings to "H-1" altough that DID bring some other extra stuff.

Any help is really really appreciated!

[Viliny]

Incase someones as stupid as me, the mode/page button allows you to find the advanced settings on the T7C

Hi there,

Thanks for this thread it was really helpfull to me.
But I'm having 2 problems with my T9CP futaba TX :

The first is that I don't have the "F/S" menu in PPM mode. So when I shut down my Tx, nothing happen..

The second is that I have "R" channel linked with "T" channel. It means when I move the throtle, the channel R move also. And I can't fixe it..

Thanks for help !

First off, thank you to "locks" for doing all this good work. I know his original post was quite some time ago but is still very pertinent today. There is no way in this world I could have ever figure out what "locks" did nor understand any of it. This shows a good and thorough understanding of how the Futaba is wired. I'm sure I speak for all who have enjoyed this post.

With regards to the receiver. I use the FrSky Fasst compatible receiver and it functions just fine with "locks" instructions. I too would like to use gimbal tilt but am not too interested in giving up the IOC features. Looks like I'll have to buy another receiver !! More good news for the wife !! Does anyone know if this "failsafe" problem is specific to the 7C tx to all 2.4gh Futaba transmitters?

Awesome job "locks". Thanks a lot !

[dimsoundz]

Dear user locks, your post around failsafe is more than perfect and very helpful!! But unfortunately I'm very new to helis world, and it's hard for me to follow up!!! Not because are not clear your writings!!! .(...not at all!!! All are very clear and a step by step understandable guide) I have difficulties because I'm using naza H unit, which differ from naza M and my tx is futaba t7c fasst and my rx r617fs!! So, both rx and tx allowed me failsafe only on channel 3 which naza h is using for throttle!! Kindly asking you to help me on how I wiil follow your guide on my naza h system!!! Please if you can advise me, it will be much appreciated!!!
Thank you

Thank you guys, this works great for me, took me forever to find this on the net, glad I did, initial test flight great, have to test RTH now!
