If you're speaking of the H501S- rebind. In terms of the H502S- use the below RSSI signal troubleshooting to verify how much 5.8 signal power you're getting from the aircraft.

Back to Basics #26: How to troubleshoot FPV issues, part 2 https://www.facebook.com/hubsan001/posts/1796671740637841

Yes.

Hello. The main solution to this issue is listed in the first comment of the video you linked to us. Re-flash the flight control firmware using the firmware and upgrade tutorial provided on www.hubsan.com ("Support", "Product Support").

Hello. For future reference, please post all non-racing FPV quad topics in the FPV section.

It sounds like the gimbal itself has been damaged by the crash. Unfortunately these gimbals are nigh impossible to repair. If you could post a video of the issue, we can confirm.

If you are asking whether or not the 3 axis will work on the standard- yes, it will. However, the aircraft's flight time will be lower than usual (the 3 axis consumes more power) and you will encounter some limitations in terms of the camera pitch angle (either up or down).

I think there is a misunderstanding. Ailsa must have thought you were asking about other cables as in 3rd party cables. If you want to see if it's possible to buy and install a cable for your aircraft, please at the very least list what model of aircraft you have at the moment.

This quite normal. The building obstructs the GPS signal.

I feel the same way about my H501-s. I just found out yesterday from some YouTube vids that mine has the Circle Fly feature! It was not mentioned in the owner's manual. Nice surprise! We like to include Easter Eggs with our aircraft. Gives pilots something to look forward to discovering :D 8-)

Hello. If I am not mistaken, did you post to a Hubsan community Facebook group?

Looks like a potentially dead or disconnected camera module. Do you see a camera and SD card icon at the top of the transmitter screen when aircraft and TX are properly paired?
