It's entirely possible I don't know what I'm talking about here.
Having said that, the clean config doesn't feel too slippery to me. I've just noticed that when the "barn doors" come open all the way on these that they tend to drop like a biplane, and this one glides pretty well like that.
As for sound, I've seen people put DAs and Zenoah's and DLEs and the like in similar planes before. I've never seen one of these, though.
