Hi Ernest,

Sorry, I haven't flown, so I can't say just yet.  I ended up going with
a larger Ford "for offroad use only" throttle body.  Keep in mind that
this is for a 3-rotor, so I need 50% more cfm.  It will idle down to
about 1000 rpm without a prop.  I figure it will idle a little lower
with the prop installed, but with the RD-2C, I will be happy with 1000
rpm idle.   =20

How much power are you developing, and how well can you control the
idle?
