Not knowing how the Mustang wing is built I am curious as to how you are changing the leading edge airfoil?  Could you give a little more detail, or post a link to an explanation of this procedure.

Bill,

 

I came a little faster on my second landing (second flight) and greased it on.  I am using the fix published by the Mustang II designer, Bob Bushby, in an early newsletter, which is to make the leading edge of the outer 1/3 of the wing that drops - more round, i.e. not as sharp.  This allows the air to flow over the leading edge more easily at higher angles of attack without separating from the wing and lets the wing keep flying longer.  After my initial re-work effort, the right wing drop at stall was much less severe on the second flight and the plane more stable leading up to the stall.  The right wing still drops first, so I plan to continue rounding the outer leading edge of my right wing per Bob Bushby’s method until both wings stall at the same time.

 

The radiator and oil cooler are located between the engine and the firewall, much like the Powersport installation http://powersportaviation.com/rv-6a_n225ps.htm

Here is a link to my engine installation before the baffling was installed that forced all air to pass through the radiator and oil cooler before exiting the engine compartment.   http://www.eaa1246.org/big_photo.asp?id=Turbo%2Ejpg
