i used to own an f2 but i've never seen an f3 live up close before. are they as big as the f2's? meaning are they as wide?

i searched but cant find answers. i'd like to find some info on the differences of the 2.

 

They are very close if not the same in size. I have F3 fairings on my F2 and they fit just fine.

 

They are near identical..the tail sections on early F3's are interchangeable with the F2
