Gil,
Very unusual for a LNC2 to be too nose heavy. I’m
not familiar with your plane, has it flown yet? If not, I would certainly fly it
first. Adding weight at the tail might make the W&B numbers look good but it
adds rotational inertia to a plane that can have fairly ugly stall/spin
characteristics. Theoretically, one can achieve a particular weight and CG with
a lot of weight at either end and less in the middle or more in the middle and
less at the extremes. The later would tend to have better spin recovery
characteristics. It has been my experience with LNC2s that a full break stall
will almost always break hard one way or the other (begin rotation). If correct
recovery techniques (rudder) are not applied with alacrity, a spin can easily
develop. The more rotational inertia the harder time the rudder has stopping it.
I would suggest careful thought and perhaps consulting someone with serious
aerodynamic engineering credentials before undertaking this
modification.

My
plane is nose heavy. I've heard about builders who put lead into the tail below
the vertical stabilizer. Does anyone have experience doing this? And would you
mind sharing exactly how to go about adding weight to the tail of the plane.
