A little enhancement to the propeller. A music wire shaft has
replaced the plastic stub on the front of the engine and a brass tube has
been inserted in the engine. Counterweights were
punched from plastic card and glued to what looked to me like bare
counterweight arms on the prop hub. A bit of brass tube was added to
a pin sticking out of the front of the prop hub
to simulate the piston on this type of Hamilton Standard
propeller. Painted Alclad Polished aluminum with flat black on the
back of the blades. No yellow prop tips in the pictures of the
plane. I have not found definitive proof but I am pretty sure this
is a 3E50 hub.
