Steve,
The extended wing is the KR2S design. The spars are built with webbing
on the front and back where the KR2 only has it on one side. To extend the
wings you would have to change the spars to KR2S design and basically build
a new wing. I had the same objective as you and am putting KR2S wings with
the larger stabilizer on a KR2.
Good luck, Larry Bell
