There's no need for anybody to get offended. Several people have taken the time to share detailed explanations of causes for ground loops, and I'll bet the OP will be able to check them out and fix his plane. The fact is the problem could be a combination of more than 1 factor. We don't know sitting behind our keyboards. I appreciate everyone who tries to offer their knowledge and experience to help solve a problem whether they get it right on the first try or not.
