[NSRCA-discussion] This email list is flawed in my opinion.

Mike:
Did you also reduce the excessive engine downthrust by 1/8" at the bottom of 
the spinner cone?  BTW, Bob Hunt talked at length with Mickey, which is how 
he got the same mods into his templates.  The nice thing is that Bob will do 
an entire set including the stab & rudder, and you can ger considerable 
weight reduction from that as well.

Another nice touch is that Bob produces the cores using the molded leading 
edge technique. It's yet another weight savings technique and it gets the 
leading edges dead nuts true with no extra effort (they're 1/16" balsa 
sheeted).  You need to make a mold buck for an additional set of LE cores 
that Bob provides, soak some balsa sheet in ammonia water and form it around 
the mold.  Wrap it with an Ace bandage and leave it for a day.  You then 
glue the molded LE balsa sheet to the cores in the shucks, just as if you 
were sheeting the entire wing.  The difference is that you use the remainder 
of the 1/16" sheeting only as a spacer for the 1st step of gluing the LE 
sheet.  Then, you go back and lay up the rest after the LE pasrt has cured. 
Takes a little more time while waiting for glue to cure, but it's less 
overall work compared to gluing/carving/sanding LE stock the traditional 
way.

He will also do convential LE cores if the sheeted LE method does not have 
appeal.
