Aerodynamics question - aileron rolls

That makes perfect sense.  Dunno how I didn't figure it out.. I really like the second diagram. Thanks DTango

But wait, we have not yet spoken of adverse yaw effects during steady state and roll onset. And the changes in roll rate based on 1g vs unloaded roll. And the effects of dihedral when rudder is pushed to create a rolling moment.

Btw first time I was attempting to do steady inverted flight in the RV, I was entering it from the top of a loop. Inverted stall speed in the RV turns out to be about 95 Knots,(unknown to me at this time) I made a very nice avalanche with out trying.

That wicked 23000 airfoil on the RVs is completely unsuited to aerobatics.  As smart as Van is, I never could understand his airfoil choice for those planes.  I bet they'd all be at least 15% faster with a nicely tuned laminar airfoil...

this i never knew....i thought the rv series were supposed to be capable of mild aerobatics?

They are extremely capable--I was commenting on the wing airfoil itself and not the aircraft.  The 23000 airfoil possesses some really nasty characteristics that, I would have thought, would have disqualified it for use on the RV series of aircraft, but that's the one Van chose.  HTs comment about an inverted stall speed some 40 knots faster than Vs would be one of those characteristics I was speaking of.

I'm all ears if you don't mind describing what the gist of each is.
