Temptation

[Jeff Hughes]

Yeah, the fuselage is incredibly stiff and strong, it's just scared me when I scratched right through it with the scriber. Luckily it's where I'm going to remove material  anyways for the elevator.

  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.

  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. 

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

    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.
