NO! NO! NO!
Control surface balancing is done to prevent flutter. Please don't even
THINK about ignoring this. While there may be an impact to the
stick-force-per-G curve, as Ed suggests, the primary purpose of balancing the
movable control surfaces.is to keep the airplane in one piece by preventing
flutter. The bob-weight is the thing that increases the stick-force-per-G.
Note that "irreversible surfaces" (ones where the aerodynamic load cannot
change the surface position) do not require balancing. Flaps are one
example. Hydraulically-boosted control surfaces are another, but there
aren't any of those in Lancairs ..... yet!
