Hi Drew,

Did the flipping activity have a net (lasting) effect on the satellite's spin rate?  I recall a discussion on how slow the bird was spinning, implying that we'd like it to go a bit faster (is that true?).  Since we're putting energy into the satellite's orientation via the magnet, I'd expect the energy should partly wind up as heat in the dampers.  Wouldn't the rest go into spin?  

Just curious,

Greg  KO6TH
