Title: Green Box Nobler balance point?
Post by: frank mccune on July 28, 2013, 06:35:42 PM

     Hi All:

     The plans show the balance point to be at the spar.  For you who have flown the G.B.N. did this balance point work well for you or should one move the balance point to another place for better performance?

      This plane balances at the place on the plans with an old O.S. .40S.  I should have plenty of power! Lol

                                                                                                      Tia,

                                                                                                       Frank

   Given the wide variety of other possible differences, you probably have to adjust it by feel. It's not too hard, the allowable range of CG positions is very narrow. Adjust in tiny increments or you can jump from one side of the right place to the other.
