The key issue is engineering of the parts. WAY back when I was an
undergraduate engineering student discovering I had no talent for pattern
design I was taught a little that has stuck in the soup within my head.

Have a look at the halves of the Pup kit and note that you can't have the
exhaust channel without either

1) A complex 3 part mould way outside the means of a short run moulder
like Eduard

or

2) leaving a cutout and adding a exhaust channel part. Note that the
Eduard kits have generally only got simple but joins (fuse half to half,
wing to fuse), and the complications of moulding an accurately fitting
part which has to mate in other than one plane has been avoided.

Frankly, if I were designing it I'd leave the exhaust channel out too,
and assume that knowledgeable modellers would easily fix it, and
unknowledgeable ones would never know !

However, I think they copped out on the kingpost, since some etch and a
piece or two of rod would put the deficiency to right admirably.
