Hey Everybody, New member here. Anybody from Massachusetts or New England please chime in. I have a finished fuselage and am about to start the wings. Two questions 1. aircraft Spruce wants almost as much to ship the spars as it is to buy them, lots of boat shops out here would they possibably carry spruce that would fit the bill? 2. Looks like my best buy on an engine is an O-235c, am i looking at a weight problem (I am building exactly to plans,I think it looks great the way it is). Hey that Volksplane looks excellent! --- Ron Wanttaja <ikvamar@gte.net> wrote: > FlyBaby > > Frank Stutzman wrote: > > What are the interface difficulties you mentioned > > in your note, Ron.
