1st cuts made & glue applied.
Hook & hook fuselage section of the Tracker reduced by about 6mm, which is roughly 210mm (81/2") IRL, & glued back together, narrower & shorter.
Outer wings glued together, as I need to be able to gauge how to work the fold parts into the wing, which has a much deeper chord than the Tracker but only about 2/3 the span, & I'll probably do the tail & tail-planes before I go to bed.
Note: A quick check of the Beau against the Grebe shows the Beau to be smaller in comparison than I expected, although most of that difference is forward of the wings.
