So have they stopped supporting the zyx? Or has anybody just flashed all their gyro,s with the new software?
This 4.0 software contains 2 images, one for zyx and one for zyx-s.

Can you do a print screen to show what files are in the zyx4.0 folder ?

Looks like they've added a governor function to the v4 firmware. There's also a new "Burst Coefficient" which is explained as "enhance the response speed of the stick" (referring to cyclic control).

I just updated both zyx and zyx-s to v4.0 using the zyx40_en.exe. Very straight forward and had no connection problem.

Yeah, Governor mode is nice to have but we need a extension module (zyx20) for this feature to work.

In the zyx4.0EN folder, there are update instructions for zyx and zyx-s in doc and pdf formats. In zyx-s update instruction, it shows the pins out to connect a rpm sensor, dual s-bus and the detail explanation of setting up governor mode using the extended module (zyx20). So, zyx-s Governor mode may be similar to Skookum and vbar.

Any point in running gov mode on the gyro when you can have it through the esc?
Wouldn't it just consume cpu cycles uselessly?

From what I saw in Helifreak.com, people prefer gyro governor than ESC governor. Gyro governor is active and ESC governor is passive. ESC just concentrates on motor speed while gyro will take both heli condition and motor speed into account to maintain the head speed.

First test flight with ZYX firmware 4.0


Hi guys,

I've recently upgraded one of my CX-ZYX frankengyros to firmware 4.0 and took it for a short test flight in the driveway. Overall impression is that the differences in flight behavior are subtle:

- piro compensation seems to be a bit better. I was able to get about 4 full piros before needing any correction input on cyclic. For some reason my 450 seems to piro much more level CW (5-6 full revs before correction) than CCW (4 full revs before correction).
- without changing anything since v3.5, I'm getting a faint (high-gain) wobble on cyclic roll after the upgrade.
- cyclic feel seems a bit crisper and more connected.
- collective feel unchanged (still vague).

I'm planning a trip to the field later today to do some more testing, including the looking into whether they solved the pitch-up tendency in FFF. Stay tuned for more...

Omg omg omg, so excited about the new firmware I really like to see if piros are truly improved. Even adding a gov function, NICE..... Tarot is putting out some superb work.

I might just test it on my night heli this evening....

That's a real pity. Did you advise Tarot that your special firmware also fixed my servo kick and lockout problem with the Align DS410M. If they know there are more issues of this, then they might add it to the official release.
