Good point about the wing folding! I forgot there was another one at the field awhile back. The fella was doing loops with it and you could see the wings flex. Right before they folded! Make sure the spar is spruce and be sure to put some fiberglass in the center section. If you start building, Red will probably share his mods.

Bad habits: Part of that is a matter of opinion, but not to get philisophical, the Sturdy Birdie imparted a great many more bad habits than the Electrostreak kit that I converted to glow and ultimately learned to fly on. I've admired the motorgliders ever since. The ES was part motorglider and part pattern ship. I want mine back, too.
