Thanks.
I will try that.
Yesterday on my last flight, after a really nice flight session, I had another issue, unfortunately was not recorded (laptop when in save mode), but I almost had a flight away, after setting the Quad to return home. The quad shake and the stabilized, start to come back and pass the home point, I try to get control and I got control back but not completely, and it has a hard landing. Nothing happened, but it race my concern. It could be the TX or Rx?
I don't have a way to test, right now. I will have to contact someone, and test a different Tx/RX.
