"SPAD" Simple Plastic Aircraft Design

[Celwin]

I only have one wing and a few other pieces cut out at the moment. It's been put aside due to other commitments. Triage... if you like...
My initial thoughts would be that a jigsaw would be too rough, but if that's what people are using on youtube, it must be ok. I thought a scroll saw or fine and thin bandsaw would work better. I've been carefully slicing mine, using a long steel rule for the straight bits and by hand for the smaller nasty bits. A good blade works well, but takes ages and still makes scruffy lines when going diagonally along the ribs. I wonder if a hotwire would work, like when cutting foam? Might make a sticky stringy mess though...
