The intake on the F1?s is normally removable. Sure makes it easy to remove the cowl and is also handy for checking things without having to remove the entire lower cowl. I modified my cowl to use one of Rod Bowers intake systems and made the removable part a bit smaller than stock.
The plane turned out looking really nice as well as your interior (along with that SWEET PANEL). I'll look forward to seeing it at OSH! Hopefully you've been having fun with it.
