Hi Joel,
You have a Phillips Aircraft kit. The Obsession was designed by Mike Harrison (I believe) and a very good flying airplane. As I recall it was a great looking airplane. Larry Phillips kitted a bunch of 60 sized pattern kits (the PA-1 which was a clone of the Aurora, The Mistress - designed by Dave Von Linsowe, the Conquest 4 - designed by Dave Patrick, the Maya - designed by Dean Pappas and the Obsession). This was from about 1985 to 1990 when 2-stroke .60s still ruled the pattern world. The Obsession was a pretty big airplane for a 60. I will have to look up the ads for Phillips Aircraft and get the specs. I'd love to see photos of the kit, if you get a chance.
I built 4 Mistresses from the Phillips' kits and they all flew great.
