One last note... this "problem" doesn't seem to be of any consequence in the air... noone (that I am aware of) has mentioned the engine flaming out in the air... just on the ground taxiing... and ONLY when the idle is low.
I NEVER have had my engine quit at all. I don't see the problem when I go out, just on touchdown.
To me it's not a problem persay...
Here is a [link=http://www.renderwurx.com/proofs/mydv2.wmv]video[/link] of my Double Vision... it shows at the end the exact "problem" where you'll notice the rpm drop significantly at touchdown. But it doesn't quit... there's also come pretty harsh walls and waterfalls that is snapping the heck out of the engine... it never stutters...
It is SOOOOO smooth on the throttle... when I give it a click it gives me a clickful... no coughing, stuttering... nada...
"Dat's what I'm talkin' 'bout"
