Hello, since I got this for Christmas, it's been nothing but trouble, my biggest problem is it won't calibrate my Tx. I just switched to a 4 channel from my JR 662(all 6 planes are being used!), I must be doing something wrong, I followed the instructions... nothing, it's all haywire. And I don't have any sound. I do if I'm in the plane, or it's REALLY close to me, I have the volume all the way up on the PC and the game. And how do I fly a plane on it that I've downloaded from the internet? Sorry for all the questions, when it was working with my 662, I loved it! Thanks a ton, Jordan
