I THINK so. but im reverse engineering this from absolutely no documentation. The yuneec manuals and documentation available are no where near the technical detail required.
The receivers have different part numbers:
Q500 4k - YUNQ500107SVC
Typhoon H - YUNTYH135SVC
…but I have also seen both referred to as ‘SR24’ and they appear to be similar in appearance as well as pin/connector layout.
The RX i purchased on ebay was labeled ‘YUNTYH135SVC’ on the ebay listing only this number is nowhere on the actual component.
When you say ‘have access to’ that makes me think it is a friend of yours. Capturing the bind protocol would require opening up the typhoon and connecting to the RX to capture the bits being transmitted from the FC to the RX - Is that something you are willing to do?
Edit: It appears that users have been able to use the ST16 TX on the Q500 copter: https://yuneecpilots.com/threads/looking-to-mess-up-a-perfectly-good-st16.17124/
Reports read that they are having video resolution issues, but lets tackle this one step at a time.
