RC Model World (
www.traplet.com ) list a plan for a 69 inch Dauntless and list a canopy CA2106CY and a F/G cowl CF2106CL for it. Traplet plan No MW2106
I believe Traplet aquired the C. A. P. plans rights some years ago and this may be the same plan.
Double sided tape is very handy to fix templates to wood or fix two bits of wood together for shaping. Use just a couple of pieces half inch long.
Presumably the under bench mounting refers to the Black and Decker type hand held scroll saws (jig saws ) - I think these have a much greater stroke and use coarser blades and are therefore more hazardous to the fingers! Buy a proper bench type electric fretsaw ( scroll saw ) as they are so cheap now ( 35 pounds sterling in UK / about 70 dollars ) and use 18 tpi blades. The pin ended type can be quickly uncoupled and inserted into a 1/8 hole to cut inside formers. Otherwise use a hand fretsaw, coping saw or a piercing saw which is easier to use on small work. Ensure the blade is used as pull saw especially on the coping saw - it is easier to saw straight.
Use an engineers file with a safe edge ( plain edge ) to finish notches to exact size.
