Well after yesterdays experience with fades and dropouts, I rebinded the 12x to my Airstar Mongoose R921 receiver and went back to the flying field today.

I have to say my experience was totaly different to yesterday with minimal, if any antenna fades or frame losses.  I am very happy with it's performance!  Not sure what happened yesterda, but after 3 20 minute flights there were no issues or cause for concern.

 I really like the feel of the radio when flying even more than my x9303 - this is a great radio with lots of extra features.
