Hi Again,
Ok, below is a paragraph from a January 1992 Kitplanes article called Birth Of An Eagle Part 1 pg 17. This is what led me to my question back in post #58.
The wings are so similar to those of a Long-EZ that a pair of Long-EZ wings could be bolted onto the Berkut without modification (though it's not recommended). The greatest difference is in a carefully generated airfoil section. Ronneberg found that the Eppler airfoil presented in the original plans had been slightly corrupted in the printing process, so new templates were made from all-new plottings.
Soooo we would probably have to talk to Dave to get the real scoop. Maybe it was just a selling tactic. I was just curious if anyone had heard of this before.
