I am still in the very early building proces of G-200 kit #11, but it's been a while since I started wandering if and how much the plane would benefit if a lopresti engine cowling was installed. Did anyone ever thought about it? Also I know that Bob Freeman had wing tip extensions installed in his G-200. Did it help alot? Were thay used also for aerobatics or only for crosscountry flights? Were thay fuel tanks or simple fairings? Thanks all. Vittorio Primultini
