Has anyone installed the "elevator balancing kit" that Lancair sells for the 
L-IV?

In my case, I added the prescribed amount of lead called out in the manual 
with the following results;  right elevator is overbalanced (heavy) while the 
left elevator (with the trim tab, MAC motor, linkage, etc)  is grossly 
underbalanced.

The Lancair "balance kit" adds an aluminum arm and lead weight as a center 
pivot to statically balance both elevators as an assembly.  The problem is 
that I just dont get a warm and fuzzy feeling with this solution.  Having two 
elevators with grossing different weights hanging on the back of the plane' 
even with added weight in the center, I find very disturbing.  Am I missing 
the obvious???

One thought that does occur to me is to remove weight (lead) from the heavy 
elevator until both elevators weigh approximately the same or at least 
balance the same.  THEN, add the center pivot arm and enough lead to 
statically balance the assembly.  Would this resolve the situation or am I 
just adding another dimension to the problem?  OR, do I really have a problem 
in the first place????

Your help would be appreciated.
