Thank you for you response, I want to mount a CGOET to a twist X mount gimbal on an h520e copter. I was advised that there may be an adapter to go from a slide mount to the twist mount.
Please bear in mind... even if you build an adapter, it will not work.
The CGOET is not implemented in the H520E. The CGOET transmits the image via the Wifi module...
but the ST-16E works with OFDM... which is not compatible.
