Oh man I feel your pain!!!!!!! I had one once on a buddy box and was telling him very calmly what he was doing wrong and he yells that i don't know what I am talking about and he threw in a couple very descriptive adjectives, well I just unplugged from his Tx and said you have just soloed! He actually landed the plane but from that moment on I had nothing to do with him and no else would either, last I heard he was at a club way north of here.
