Gun,

I agree, it sounds like you might be having transmitter issues. I have been flying Spektrum/JR since day one...first with my 10X and modules and now a 12X (and still the 10X too). I have flown the Spektrum 9000s, JR 921s, 1221s and 1222s in my F-15, F-16, T-45, Velox, Lightning, BoliCat and Tucano. I have well over 1,000 flights combined between the jets and have never had a single issue (other than having the transmitter antenna pointed the wrong way one time which ran the number sky high) so I am sold on the technology.

Good luck with your search, but I'll bet it is the transmitter. If you are having issues with multiple set ups...that is the common link.

Cheers,

Beave
