Hey Bmodelflyer,
I recognize that you fly at Woodland/Davis Aeromodelers.
Here is my Dora from last year at their Wings of Victory.

I am not going to use a set of calipers and micrometers to make the conversion from the P-51B to the A-36.

I will be using "TLAR" for the most part.
I will probably be working on the dive brake design long before I finish the airframe out.
One of the previous owners of this kit had built the plane to the point of sheeting the wing and then stopped.
This makes it perfect for me to figure out how to fabricate the dive brakes.
