RE: Need Help deciding please...
Given that the F-18 is a foamy and the Pilatus a Balsa plane, I would go with the Pilatus hands down.
I have several 90mm and 70mm foam jets. Though I like them, I view them as "short lifetime" planes.
The foamies get dinged up VERY easily and they are not as robust as that Pilatus.
The Pilatus will likely serve you for YEARS, the foamies just a few seasons.
