YS .91 idle setting

[Craig Miller]

I have an AC that I've been flying with for the last two summers, and I 
don't think I have the idle down to 2000 RPM, maybe at about 2400. It might 
be that you have the idle too low (especially for a new engine). All you 
need is an idle slow enough to land, and of course so the ship doesn't start 
rolling before announcing your take off!
