Saw a thread on the tarot 680 and was poking around YouTube and found this video. http://youtu.be/ZlYwtbZofYU Not sure what this guy is saying, but around 2:40 into the video he calibrates his compass by spinning his body around instead of turning spinning the hex. I think I like that. I always feel like I'm going to drop my quad when I spin it. By the way, if anyone knows the language can they figure out what the guy in the tree is up to?
