Hi,

I really needed some help setting up my new radio Futaba 16SZ with a Futaba CGY750 Flyberless system.
I have been looking into many videos and I know its a new radio but all I like to know after creating a NEW MODEL, what settings are needed to adjusted for initial setup. If someone has this particular radio I will appreciate sharing this setting info and if not then I would really like to know about these initial settings from any futaba radios.

I have gone through many Futaba CGY750 FBL setting videos and now I have pretty good idea but still I can not go on without initial radio setup.

Any help will be highly appreciated.

Many Thanks,

Arshad

Ok,

As you are aware, the vast majority of the tuning of the fbl system occurs in the 750. Transmitter configuration is comparstively minimal.

We use the transmitter for the following:

1. Setting cyclic rate via AFR/dual rate in any flight conditions where you want slower response than the maximum rate set in the cyclic rate menu in the 750.

2. Setting head gain (ail and ele gyro gain adjust as one parameter in 3D mode) and tail gyro gain.

3. Toggling between the two available banks AKA bank switching.

4. Setting head speeds if the 750's internal governor is used.

For #1, you have perhaps three flight conditions plus throttle hold. If you ever do any hovering, set the AFR/dual rate for AIL and ELE to 75% and tune to taste from there. Use some expo if you want as well. Adjust the other flight conditions for the desired cyclic rate. If 100% rate is too fast, then reduce the cyclic rate in the 750 a little. 280-300 d/s is a good start. 510 d/s works well for the tail (also set in the 750). set the maximum rates in the 750, and anything less in a given flight condition in the transmitter.

For #2, set head gain in the transmittter's gyro menu to 70% for aerobatics. Use at least this much in hover. Some models will allow A LOT more in hover if the swash rate for hover only is reduced a good deal. Set tail gain to about 65% for aerobatics or as much as you can run without a wag. In hover you can run about 90%. In the 750, make sure the SBus channels for head gain and rud gain correspond to the transmitter channels that tune those functions.

For #3, refer to the gyro and transmitter manuals and use one of the digital channel to toggle between the two banks. Turn bank switching on in the 750. Assign the bank switching digital channel to your flight condition switch so the banks switch as desired. You don't have to use bannk switching. Many guys just tune the gyro as one bank for all flight conditions.

For #4, I'll reserve comment until I know about how you are handling your governing. If you use the ESC governor, you use the transmitter's throttle curves to set the desired headpseeds in your various flight conditions. The 16 is not unusual in this regard.

Ask specific questions, and I'll fill in any gaps.

SENSER ERR
Many thanks for your help. It is been very helpful.

One thing I forgot to mention which I suppose to is that when I turn ON the Gyro 750, the first screen shot appears is " SENSER ERR"
If I press any key on the 750, the manues move forward fine.
I am connecting this 750 gyro via a Futaba S-BUS.

Is this a problem with 750 unit. How can I check if the sensor or the Gyro 750 is OK ?

I will appreciate any help.

Regards,

Arshad

Dr Ben I also just upgraded my 8FG to the 16SZ. Going to be a learning curve for sure. My question is i should only have to program the transmitter as the 750 has already been set? Still trying to figure out how to set the gains for the trim flight. On my 8 I used switch SF for the different gains for the trim flight. To me the gyro setting menu is a little confusing. Thanks for your help. Chuck
