I took my OV-10, and found there was another guy with the same ARF. The ARF comes as an OV-10D, but he had 1000 hours in the OV-10A in Viet Nam, and so he had kitbashed his into an A version, and made it an exact replica of his plane. He had a lot of interesting tips and information about the full-scale plane.
Tony Quist and several other Horizon Hobbies staff pilots were there, flying several of the other Hangar 9 models also.
I only met a small fraction of the attendees, and missed the evening dinner. But it was a fun time. I would highly recommend it. They do it at the beginning of June every year. Below are some random photos from the event.
