These directions leave a lot to be desired.

I need to set my gyro to work with the BLS251 narrow pulse width servo.

First off - what the heck is the "Gain Switch"???

My assumption is that I should set the gain below 50 in Normal mode, and then set it above 50 in Idle up mode, and then use the Idle Up switch as this Gain Switch. Is that correct?

Next - It says on page 6 to access the servo configuration mode to hold the rudder stick full left and toggle the gain switch continuously after powering on the gyro.

- Does this mean I have to be holding the rudder left before and while I'm turning on power??

- All I can get it to do is flash when the idle switch is in idle 1. It is not lit in Norm mode (gain below 50). It flases 2 times. It says move the rudder stick left or right to change the servo type. No matter what I do, it still flashes 2 times.


Arghhhhh!!!!

NEVERMIND!

I finally got it. Apparently I never actually got it to the servo configuration mode.

Once I did. it was flasing 1 time even with the rudder in the center position.

OK - life is good again.................

Those are the old instructions. For the newest firmware version, you don't need to do that anymore.

Just set the gain below 15% (If you're using spektrum) and enter the config normally.

You think your kids are expensive now?

Just wait until they move out!!

So I'm having issues with initializing. Since I have Spektrum, I tried binding with the rudder off center like the manual states and that didn't work. After turning the TX on and the RX on, the system would initialize, but the tail servo would not move with rudder command.

However, I had Norm mode gyro gain at 70, and Idle 1 at 30 (rate). If I toggled to Idle 1, then the tail servo would respond. When I went back to Norm mode (AVCS), it would still work. But if I turned everything off and then back on, the servo would not work again.

Aaaarghhhhhh!

So I switched Norm mode to a gain of 30 (rate), and Idle 1 to 70, and then I re-binded the system in Norm mode (but with the rudder centered). After turning everything off and then back on, it worked fine. So then I set Norm back to a gain of 70 (AVCS). I turned everything off and then on, and everything worked fine.

So what the heck is going on? What is the correct, simple way to bind this thing, and to get everything working right away?????

How do I find out what software version I have??? It doesn't seem to be on the gyro, or the box, or the manual.......

Thanks guys!

Other than these binding/initializing issues, I really like this gyro. It is unbelievably tiny! I completed the full configuration, which turned out fairly straightforward. I also like the fact that after initializing, it is deadly silent - no buzzing or jumping. I also like the fact that quickly moving the rudder stick back and forth 3 times re-initializes and centers the servo just like a Futaba gyro.

My DS760 came with the latest firmware (v1.07) already flashed to the gyro. I verified this by plugging it into my laptop via the USB cable after I set it up.

What radio are you using?

I fly with the X9303 and I use the gyro sense menu. The DS760 is similar to Futaba gyro's with everything above 50% is HH mode and everything below 50% is normal (rate) mode.

To enter configuration, I left the gyro sense menu "INH" and set the gain for Aux 2 (gyro gain channel) to 5%. Then I went into the servo configuration by holding left rudder on power up and then toggling the gain switch. The DS760's LED should flash. By moving the rudder stick left/right you will change the number of times the LED flashes. For the BLS251, the led should flash twice. Once you have that selected, power off and plug in the gyro.

Then I went back in my Tx menu and activated the gyro sense menu and reset the Aux 2 to 100%. Then I went into the gyro menu and set the gain initially to 70 in HH (which is actually 60% on the gyro). Then you go through the normal set up.

As soon as you power up, toggle the gain switch and the the servo will "twitch" twice to verify that you are in the configuration mode. If your servo reverse is properly set in the Tx for your rudder servo, you set the gyro direction by moving the stick to the left. Then toggle the gain switch once. The servo will twitch once to let you know you set the gyro direction.

Then you set left and right end points individually. Once you are done with the endpoints, toggle the gain again. The gyro will twitch the servo 2 more times to let you know you are done. Power off and wait several seconds and then power back on.

That's it. You have just finished configuring the DS760. Mine initializes as soon as my tx and rx connect. I can easily enter the configuration menu anytime I want to.

You will find that the stops are very quick with no bounce back. I left the rudder ATV's at 130% from the Logictech 6100. The piro rate is not only consistent left to right, but the speed is very quick (quicker then the 6100 with the same rudder endpoints). If you did not get the USB cable, I highly recommend it. Not only will be able to flash new firmware to the DS760, but you can adjust the advanced parameters if you desire.

Gary,

I have the 9303 radio.

I have the gyro "ACT" and set to "AUTO" So does this make my "Gain Switch" the idle up switch?

When you had gyro INH, what was your gain switch???

My point in the last post was that I was able to successfully get into the configuration mode, and was able to configure. But after powering down and then turning everything back on, the gyro did not seem to initialize, and the servo did not move when commanded.

On page 12 of the manual, it says there are "difficulties" with the Spektrum radios. I tried what they suggested with binding with the rudder stick off center, and that didn't seem to work.

RC Heli magazine also had issues with the Spektum radio, so I was wondering what is actually working!!!

Yes, in your case the idle up switch is the gain switch. I have had similar issues with my Spektrumized 9303. On mine I had to bind in HH mode or the heli would never initialize in HH. This occurs with the new 1.07 software as well. It gets frustrating because Angelos will tell you it's not possible but I can repeat it everytime. I'm not the only one having issues. I've heard and read accounts of others w/ 9303's having sporadic issues like this. It is a great gyro but it can be very frustrating as well.

I understand this problem only to occur when the gain is toggled via the flight mode switch? I've always dedicated another switch for gain, and haven't ever had difficulty with the DS760 in the slightest. Super simple, IMO.

Haha Dave... It just sounds more complicated than it really is.

Rock,

For the initial calibration, plug the gain lead into Aux 2. Then set the Aux. 2 switch as ACT (not for the gyro). Then set your Auz 2 endpoints to 5%. Then bind your rx. Once you bind the rx, power off the heli and bring your Aux 2 endpoints back to 100%. Then activate the gyro sense menu. In the gyro sense menu, choose the Aux 2 switch to be able to switch between HH and normal modes. To simplify everything, do not set the switch to AUTO.

Once that is done, go ahead and set the Gyro Sense numbers to 60-70% for HH and 30-40% for Rate mode. Anything above 50% is HH and below 50% is rate mode. If 50% is the starting point (or zero) than 70% (20 points from 50) would actually be 40% gain on the gyro. Same goes for 30% in rate mode (20 pts from 50 would equal 40% gain). Since 50 would be the starting number, 1 pt of adjustment in the Gyro Sense menu would equal 2 pts. of gain on the gyro.

Now once you turn the heli on, immediately start toggling the Aux 2 (set for gain) switch. Mine always goes into configuration mode after I toggle the switch 2 times.

Remember that you only have to set the low gain (5-10%) to the Aux 2 endpoints whenever you rebind. Once it is binded, you set everything back and you should be able to go right into configuration.
