Mitch,

good stuff. From the sounds of the latest RCU wisdom, 2" is where it's at. Jim Kimbro himself replied in the thread inquiring specifically about dihedral:

The essence is a flat top wing (as is often the case with classic pattern designs).

Regarding wing TE taper you might be interested in reading Jim's article in his rationale for a double tapered wing. It's an issue of roll vs tracking (loops) performance that dictates what the designer chooses. Dick Hanson also discusses this in his article on the Tiporare which originally had a wing with a planform similar in concept to the Deception. Later, GP modified the design (I don't know whether Dick had input on this) to include a wing with (additional) equal taper planform.

Just a little food for thought.

David.
