I have been flying power kites and buggying for almost a decade now and have decided to set that aside for a while, if not for good... lots of reasons, long story. I love the control of quads and in spite of selling off all my main gear (buggies and all), I will still maintain a symphony conversion that riffclown helped me with a while back. I'd like to get a Rev in the future for our annual beach trip. They are pretty costly new, so I am considering used, but not looking to buy right away. I'd love recommendations.
