Im not an expert, but when this happened to me with an Etronix, it was a problem with the DHSS version. Not sure if that has been the same with the others on here, but when mine was replaced with the new FHSS version the problem disappeared.

CML were fantastic with me. Hope you have the same result.

Unfortunately not...

This is a FHSS, Core RC CR151....

The first TX, RX set I bought is fine, not a single issue, and works like a dream, the second RX i bought for my 2WD car, is failing to bind... the LEDs are doing a different thing to the original one that bound ok, would check part numbers but this would mean removing the one that works from some very very sticky servo tape....

I guess it is just one of those things, cheap items are that way for a reason, and it prob costs too much to put a End of Line test in place...

Cheers
