 Craig -
 
 Thanks for the info. IMHO, this should be the way they do the ailerons  too.
The Columbias have the bob weights and they are really nice.
 
 We melted our own weights for the elevators and they worked well. We also
 did this on the ailerons, but the space available made it a real PITA to get
a good design and then to fit it in that shallow, narrow well in the  TE of
the wing.
 
 Cheers,
