Default CG

Thanks for the insight...Insightful

The Boeing 25% of MAC is relative to the trailing edge of the wing at the side of the fuselage. There is a small
flair angle to cuff the fully extended flap inboard edge. Will test with an enlarged 1948 Nabisco shredded wheat cereal box B-47 from a 40' high balcony and see how she does. I will cut from balsa and lite ply.

George Maiorana's Tu-95 CG test used a much smaller balsa glider.

Because the B-47 gear are bicycle there is little weight transfer fore and aft of CG. Outriggers swing
forward when retracted.

Bernie Lund returned my call this evening telling me his CG is exactly as I had calculated and Boeing declared for 25% of MAC. Bernie has his #3 nearly ready...again...;^) This time he has a huge number of plug locks to prevent what haunted him twice... :^( Looking forward to seeing Bernie's next flight, maybe in person considering how economical flights are to Vegas from Houston. Will post my B-47 glider results when I toss my cookies in Kentucky.

Decided to wait until our Epilog laser is set up and cut a larger CG test shape. Sam left this morning
going to Arlington to pick up the Epilog Fusion 32" laser.
