I'm beginning to wonder if it's just the plane, I adjusted the thrust line last night and changed the sideways thrust as well as it was pulling to the right and flew it this morning and it was the same (except have sorted the pull to the right).

Caught me unawares as after flying it I flew my Extreme Flight Extra and nearly cost me the plane as I was so used to virtually no input inverted and when I put the Extra upside down and it started heading for the gound initially seemed to be giving input but to absolutely no response in comparison and just kept heading for the ground until I gave it a whole heap more !!!!!!!! Bit of a heart in the mouth moment !!!!!!!
