Default lead tail ballast

wrote:
Over the years ,my PIK20D ,not to mention my self ,has gained some
weight.
The cg with me aboard is now located forward of the mid range although
still
within limits.

I would like to add about 6 pounds of lead to the tail to shift the cg
to the rear
half of the allowable range. Anyone know the best way to attach the
lead tail
ballast?

Some ships (my LS8, for example) have an approved mounting bracket and
procedure. On the LS8, there's a convenient "pocket" between the aft
bulkhead on the vertical stab and the rudder.

The first place I'd look is the PIK maintenance manual.

If you don't have a tailwheel, I've seen some pretty slick designs
using the rubber tail skid. Essentially, part of the skid is hollowed
out and lead is poured in. You need to be a little careful in terms
of leaving enough wall thickness to take any side loads and maintain
the contour of the bonding surface, but it seems to work. It's hard
to get much more than a couple of pounds in there given the typical
skid dimensions.
