<DIV>Jeff, the TAVS type of composite often places a polyurethane semi
rigid foam between two layers of fairly light glass cloth. Glass is easily cut
into because it is quite thin. Once you break into the urethane foam,
cutting goes very fast. Polyurethane foam makes the fuses both rigid and light.
Composite ARF's products first introduced this construction type to the modeling
public with their large 40% TOC planes. It's a great method for building
models. Rest assured the Temptation fuse is very strong. Believe me I know. I
have stressed mine to max and expecting to pick up pieces, yet surprised to
see the plane intact.</DIV>

<DIV>The gear mounting plates Guerin/Davis et al have designed in, are
the most robust in the business. The European manufacturers should
copy this approach. I have seen too many ZNLine and PLProd gear plates break
prematurely on a slightly hard landing. </DIV>

<DIV>When you scratch the glass with the scriber of the height gauge, be careful
not to cut the glass. </DIV>

<DIV><FONT face=Arial size=2>I cut the hole for the wingtube on my Temptation
tonight. That is really wierd how stiff the fuse is, even to squeeze it, but
how easy the dremel sanding wheel ate through. I have a set of vertical
verniers that I used to scratch a horizontal line at the proper location, and
it easily broke through the gelcoat. Not like all my previous fiberglass
planes at all.</FONT></DIV></FONT></BLOCKQUOTE></DIV>
