We're gradually gaining a few more people in the West Michigan / Grand Rapids area - maybe next year thing's will take off! Things we've discovered so far: the control surface hinging is stiff - consider a double (both sides flute cutout) hinge; a safety line from the 'fuselage' to the engine (as is required for CL combat) is good - could avoid losing an engine in a corn field; consider 2 servos for ailerons to reduce wing flexing; consider 2 pieces of 5/32 music wire for 'spars'; make plenty of spare engine mounts; make a fuel-line slip joint in your throttle linkage to save your throttle servo in the event of a crash.
