Hull or engine parts? The hull isn't worth anything as far as I'm concerned, a really bad design that used a lot of Band-Aid fixes. The engine is slow and very touchy to needle settings. Never mess with the low-speed screw or you'll never get it to run right again.
Are you looking at one or already have it? Either way, it's not worth much more than the price of the used engine and radio system.
Sorry, that's just me being very honest.
