We have hotwired the fuselage for the RC quarterscale for the two place
Marske Pioneer 5.

Mat,

I was curious about the hotwire cutting. Was it a stricly 2-D cutter?

I have seen one company that makes 3-D foam cutters that can cut very
elaborate shapes, though this may very well be out of your budget. It
would make the transitions between sections much smoother.

Also regarding the hotwire cutting how will you accurately align each
section?

Why did you not cut a groove/slot/hole along the centerline of each
section and insert a pipe or beam to align them?
