As to your first question, the plans have not changed in all the years since the early 60s.  Only a couple of mods came out in all that time.  One for the rear spar carry-through and one for the rudder-to-tail wheel spring.  Both were very minor in nature.  As for the second question regarding spruce, we used Douglas fir on all the fuselage structure including the firewall and tail components per Pete Bowers.  Fuselage skin and wing ribs were made from 1/8" marine grade mahogony. It must have water proof glue.  You think the spruce is expensive try buying aircraft grade mahogony sheet.  The spars we did use aircraft grade spruce and I would not recommend anything else for that.  Your life depends on it.  You can buy a wing spruce kit from Aircraft Spruce and it has all the spruce you will need to buy. -----Original Message----- From: Darrel Morisse <dmorisse@northland.lib.mi.us> To: FlyBaby <FlyBaby@listbot.com> Date: Tuesday, November 16, 1999 11:30 AM Subject: New list member FlyBaby I have been aware of the flybaby for a number of years, but untill today I had never seen the plans or the plane up close (all my wooden airplane experience is with Pietenpols).   Then, I came upon a treasure at about 9:30 this morning... a 1971 issue of the complete EAA plans for the fly baby. I have had my nose burried in the book and on every flybaby site I could find all day. NEAT little plane, and after a Sky Scout and an Aircamper the construction would be a snap. AND I happen to have an EA-82 handy without an airframe behind it ;-) hmmmm grey cells are turning ;-)   Have there been any major changes to the design since '71 (safety wise) ?   Also, being in Southern Ontario, aircraft spruce is hard to get, and worth more than gold when you get it...has anybody used a different wood for the plane (with appropriate sizings of course)?   Mike Lund   Welcome Mike.  I don't have the answers you're looking for, but I'd like to hear what others have to say.
