Our friend in the CH's mastery of English appears far better than the vast majority of VAFer's skills the multitude of Swiss languages. I read his comment as a reference to originality; so, disagree if you want but I'm with him.
Building a well designed kit takes skills. Having the advanced skills and ambition to take on the subject aircraft should be a point of pride, not ridicule. Got to see Flyboykelly's Radial 8 in person. There's a reason it has been featured on Magazine covers and subject of EAA articles. He closed his round engine thread because of similar "stuff".
Throw more stones. No one will judge you.
