Water-Born; I didn't have to cut the rear lower brace for the cowl to clear. The spark plug has to come out, but that was it. Yes, the horn brackets suck. Very brittle. The landing gear on my plane will be replaced this winter, with a TNT gear. (Same for my Hurricane) The 22-10 prop does have a clearance problem, if you happen to pound in a landing. I too epoxied the tail section on. These are all rather std precautions though with ARF planes. You'll really enjoy this plane. Try going to www.downonthedirt.com and see the video of Joe flying the plane......[8D]
