DJI F450 failsafe problem

HI Guys,

I have brought a DJI F450 quad from a friend who did not like it and only flew it a few times.

It flies lovely, but the failsafe is not working now,

The failsafe was set so on hitting failsafe it would just land immediately, and this worked for the first few weeks.

But then when I went to land last week on failsafe it landed but did not shut off the motors as normal.
I took it off failsafe and the motors still just kept running at idle speed.

As soon as I hit the fail safe again the motors went to full throttle.

I have loaded the DJI assistant and everything seems to be set correctly and I have re calibrated the Radio (DX8)

It still flies fine in all modes but as soon as I touch fail safe it just goes full throttle.

Also after 3-4 minutes of flight I get a flashing red light with the occasional long flash.

Any ideas?

Currently flying stock setup with 10 inch props on 3s 2200 lipo.

Thanks

Pete

try to rebind the receiver in the fail safe position of the stick.
You should bind the receiver when the throttle stick is down.
