Ching-Ho,

This is the approach that I always use ...
* Use the monitor in the software or programming box to check that the rudder is showing movement on the rudder channel to match the movement on the Tx rudder stick - if not reverse the Rudder channel.
* Put the Tx into rate mode, and give Right rudder - on a trex 450 this should move the servo arm forward, pulling the rudder rod FORWARD and the slider Towards the hub - if not go into Servo Reverse in the software or programming box and change the setting for servo 4 (note this change is in the FBL unit not the Tx)
* With the heli tail towards you, nose away, move the tail sharply to the RIGHT, again the tail servo and rudder rod should move FORWARD, if not the go to the Gyro Direction menu and reverse the setting.

Hope this helps,

Mike.

Interesting to see the upgrade file included with v3.0 (v3.01) is only 30KB in size, so it looks like it would fit in the ZYX's MPU.

Flashing the ZYX-S v3.01 firmware into the standard ZYX does not work (no leds at powerup).

Flashing it back to ZYX v2.5 restored it.

It will be interesting to see what it does in my early CX-3X1000 versions, that can be crossflashed.

I was just about to try it on my "bricked" 3X1000, glad you got it working again though

Mike,

Thanks for the advice. I did a quick check this morning before going to work. I moved the rudder stick to left and the leading edge of the tail blade went to right. I moved the rudder stick to right, and the leading edge of the tail blade went to left. Therefore, tail control via rudder stick was fine. I will double check tonight to make sure that the rudder rod will move forward and slider moves to hub when giving right rudder.

Then I checked the compensation, I moved the tail to right (nose to left), leading edge of the tail blade went to right. I moved the tail to left (nose to right), leading edge of the tail blade went to left. So tail compensation was doing the opposite as to "When you yaw the heli, the leading edge of the tail blades should move to point back to where it started." I will change the tail compensation direction tonight and check again.

Thanks,

Ching-Ho Cheng

BF, thank you so much. Once I receive my ZYX-S, I will try to upgrade the firmware to 3.0.

Looks promising though, that yours will come back, when a CX firmware update is released.

boy, the CX guys have really fallen behind. Now I wish I'd bought the Tarot.

That's what I'm hoping

WIth V3 of the PC software and the XYZ-S I think that you're right

Can the zyx be used ona fb heli ( all gyros) not just the tail i mean?

Not recomendet to use on FB heli. It would fight against the mechanical stabilisation.

Not only is it not recommended, there's no point. All it does is replace the flybar and it's associated imperfections (friction and slop). It's not like the Flymentor that will keep your heli in a level hover for you (or recover from your mistakes)

Lol, no it does not mimic friction, slop or even the drag at all! Together with the extra weight of the mechanical flybar and flybar cage and associated parts, you'll actually get rid of most of the mechanical imperfections altogether when going flybarless.

The electronics merely compensate the cyclics against torque (and ballooning) that would otherwise have been compensated by mechanical flybar in a less efficient way. It'll also quite obviously do the entire swash mixing in the box, rather than in your radio system.

The 3-axis gyro system will make sure the cyclics will also maintain their attitude in wind gusts or flight moves when you do not steer on cyclics, which translates to a somewhat more comfortable control.

As a result it'll really feel much more locked in, almost as if it's on rails going exactly how and when you steer. Add to that a (slightly) higher pitch range and usually faster flip and roll rates too, and it's a pretty big deal.

Therefore, the difference between flying a flybarless helicopter often is nothing like flying a flybar helicopter. As such it's not accurate to state that 'all it does is replace the flybar and associated imperfections', there's far more to gain.

You are correct though, using a true flybarless stabilization system on a flybar helicopter is a no-go, it just won't work, unless you use it as a stand-alone gyro.
