Chevy,

See the picture (taken before final assembly). The balanced portion of the elevator is forward of the hinge line (in blue) for aerodynamic balance. Look close at the left tip in the extended section and just behind the leading edge is a small chunck of 1/8 lead solder to static balance the elevator. The elevator will remain level with out any control rods attached. With only 5 or 6 flights, I have not noticed any difference except that I have a little less elevator throw (about 3/8-7/16" ) than the stock throw (1/2" ). Nothing extreme has been tried and except for a brief blip to full throttle on take off, most flying has been at about 1/3 throttle, just putting around.
