E30Z Evaluation possible sale

Hello all, My drone background is mainly in Pixhawk and a DJI Mini2 that I use just to tinker with. I recently bought an H520E that came with a E30Z that I obviously can’t use so I’m looking to get it evaluated and most likely sell or trade it for something that will work with my H520E.

I’m looking for someone local to western Washington that I could meet with that has a H520 that I could test my E30Z on for basic functionality.
In addition I’m looking for a trustworthy source I could send it to for evaluation and update as needed. FYI I was able to briefly mount it to an H480 at which it did come to attention when powered up.

Has anyone ever tried and had any success with other 5.8 video receivers or monitors with built in 5.8 receivers with multiple channels? I realize this may seem odd to some but I’ve built a number of drones using a number of different 5.8 transmitter and receivers and it’s just a matter of matching the channels to sync the images up.

To summarize I need someone I can send my E30Z to for evaluation and possible updating as necessary.
In addition I also have a CGOET that has a good image but gimbal spins continuously.

Thanks all, Matt

The spin on the CGOet may be a calibration issue.
There are two physically identical version of the CGOET. One works on Typhoon H, the other on H520. @h-elsner has developed calibration GUIs that can either calibrate or identify issues for both versions. You will need to assemble a calibration/test stand and become at least basically familiar with the GUIs. The GUIs and the needed documentation are available for download on a webpage provided by @h-elsner.
