It might be interesting to put a different wing on one side and fly it.
Seriously, If I had a pair of wings, I'd go fly. I don't think it's
that big of a deal. If I had NO wings, I'd sure go with the improved
airfoil.
Many people extol the virtue of different wingtips. Mooney just cuts
'em off at the end, and they also have good results. \
The main thing is to build them with identical twist. I've seen some
strange aircraft workmanship. Do a good job and make 'em right.
Jeff, GO FLY. I wish I could too.

Subject: Re: KR> angle of incidence, AS504x
I have read much on the new airfoil from the posts... but I am still
left
wondering....
what are the net effects of the new airfoil over the raf48?
I have 2 sets of wings. DD and another standard set that I've picked
up...
I am seriously thinking about selling them and building out the new
airfoil.
Anyone have an idea if the effor would be worth the work?
