None in the logs. I was not told about the ground loop when I bought the plane- I found out about it from the grand old interweb when the builder of the plane(the original owner commissioned him to build it) mentioned in another forum how he had to go rescue the owner when he(the owner)ground looped it. A couple of posts later there is a picture of my plane so no question about whether or not it actually happened. Also I found a bent rim in the trailer- and there is scarring on the tail-further evidence
