Hi Paul,

I am currently building a Cozy MKIV which I plan to use a NA 20b.  I am considering one of many fuel/ignition options.  One idea was using 3 synchronized Aeroconversions AeroInjectors (Aerocarbs...35mm 90-125hp each).  One feeding each rotor.  What are your thoughts regarding this setup?  Thanks in advance.

Best regards,
Jim Tomaszewski

BTW..your website is a great asset to the rotary homebuilder!  Great job!


I think you would be giving away some HP. The engine would
run of course. You could get about the same HP with a 2 rotor
P-port. The 3 rotor P-port engines use 3 intake tubes
with 2.76 square inches of intake area each.

A 35 mm carb is 1.377" in diameter and only 1.49 square inches
of intake area each.
