At 1/71 it's about as close as you can get. The rivet treatment, however, ruins the kit. Looks like a really bad case of acne.
One of my "to be completed someday, maybe" projects is the Airfix Draken. The intakes are the only really serious problem with the kit. I grafted a pair of the Revell intakes and the results are really nice. The Heller kit, which offers both single and two seaters, is much better and I have heard that the Hasegawa kits is by far the best.
My Airfix Draken project is so old that it predates the after market products, Bang seat, instrument panel, cockpit sides and floor are all done from scratch, as are the landing gear bays, pop out generator and a few other odds and ends.
If the Revell kit shows up again for a decent price grab it. It's a really nice kit for the history buffs.
