I don't know, I try to diagnose and think I have it figured out then something happens. Everyone I talk to here on the forums are always telling me how their gear works so well, which is frustrating because mine doesn't, same gear. I make changes, take certain precautions, and still get failures. I ask again and everyone else has no issues. I am changing Rx brands and style of Rx again and gonna try this. I am honestly tired of this by now.
I have had these Rx's for less then 5 months, and people tell me they have had theirs for years, never a problem. I make sure the Rx's are not near metal pushrods, CF, other electronic or the battery in every plane, I still get problems. Others stuff the Rx in their planes like an after thought all tangled up in wires next to the ESC and never an issue. I fly away from power lines in plain line of sight in wide open fields, loss of signal. Others fly behind trees and buildings FPV and no issues. I just dont get why i have all these problems. I have replaced my Tx once on warranty now and gone through 5 Rx's of two different brands. Go figure
