The biggest thing I've seen is the install of the aluminum on the FFR seems like never ending drill,rivet, drill,rivet! The fiberglass also needs riveting and I added more rivets than called for but the install time was far less. (I've built both)
FFR has a smaller footbox (at least on the MKII) than the Hurricane. My Hurricane is actually a little too big.
