Justin,
Keep in mind that the RAF 48 airfoil is not tried or proven, especially for the
KR2. There is no documentation on its performance in a wind tunnel, just
homebuilders reports. The AS5048 wing has been tested and then used in a couple
of KR2 aircraft and found to be superior in cruise, as well as being able to
bleed energy in the flair when landing. Troy Pettiway found big improvements
in all around flying characteristics for the new wing. Troy's is one of the
fastest KR's since he has won the Copperstate a couple of times I think; that
should say enough. Unfortunately one of the things you will find in aviation
is that alot of people are against change and resist it even though all the
evidence suggests otherwise. Case in point is the success of solid state
electronics; yet the FAA will not embrace it for older points triggered
magnetos. Your friend may be well intentioned, but read the write up on Mark's
site abut the new wing and what all went into its development and you will see
why all the newly built aircraft are using it.
