Mark and Paul
I do not have any specific pictures of the engine
on the Cruiser, but here is a file on a 2place
hot rod based on the KIS 2 place fuselage with
the engine. Astretcer band is added between the
top and bottom moldings to incease the height
of the firewall (the fuse is also shortened in
front to do the same thing as well as Cg control)
a four place wing section is used as well as four
place fin and horiz. the engine drawing is not an
exact M14 but is a genaric 9 cyl radial scale
to the right dia. With variable pitch the dia of the
prop could be reduced and blade area traded for a
higher Cl (working angle of attack). I have not
bren able to ferret out exact prop rpm - engine
ratings are quoted at 2800 - probably crank speed.
Some applications on slower airplanes have used as
small as 6ft 6in dia tho the unlimited aerobatic
applications go over 8 ft for vertical work and
max drag down hill, if you stumble on to the gear
ratio let me know, and I will run some prop sizing
calcs. - Vance
