Boy! Do I feel stupid! I have this book, of course. But, carelessly, when I consulted it, I started at the drawing of the HP 42, and went forward. As you observed, this drawing is a few pages BEFORE that. Thank you. Regards, Nick.
As you may have suspected, my goal is to convert the HP 42 to the HP 43. It doesn't look too difficult. Just a new fuselage, new empennage, one
less engine and an upper wing that is shorter, narrower in chord and with a longer flat center section. All these wing modifications ideally need to be done while preserving the excellent fabric detail of the kit! But it will look neat when done. I can't start it until I have finished my current conversion project: an AZ Models 1/144 scale Fokker F7 - aka Avro 10- into an Avro 642- 2m. Regards, Nick Filippone
