Hobby Hangar is the place that sells the 52" span ARF but I don't know if they sell the parts separate or not. They do sell the plane as a laser-cut kit as well if you want to build your own. Prices are around $120 for the kit & $280 for the ARF if I remember correctly. I've seen good & bad comments on the ARF but I can vouch for the quality of the laser-cut kit. I don't care much for the plastic parts that came with it (seem a little on the flimsy side) so I'll probably end up ordering the fiberglass replacements they offer when I get to that stage of construction.
