Start/Stop button doesn't work

[Bullshark]

My Red button doesn't do anything! I'm Still able to take off using the Slider on the screen(Takeoff) ,and when landing I use home mode. I tried going into the hardware screen, everything showed it worked except (B1) the start,stop

Is this a new purchase? NO, do not ignore it... if recently purchased I'd send it back for replacement.

Normally this kind of issue might be solved by going into the ST-16 secret menu for full calibration... however I've never seen a report of B1 not working, being solved by that calibration process. Usually one of the sticks not fully responding...

I've had it over a month.

Where did you get it? If the store you got the craft at will not replace the ST-16, you can certainly open a tech support case with Yuneec, and send the controller back to them. I suppose if need be, you could look on YouTube for any videos on how to swap out that B1 button, if you're handy with small electronics.

It goes without saying that being only a month old, should you choose to undertake that repair yourself would invalidate your warranty. Just know that warranty repair or replacement is at tech support's discretion and on their timeframe. And definitely do not fly... if you crashed and they subsequently found out that you were aware there was a hardware issue with the controller... that crash would be deemed to be pilot error.
