Guys, I am building a kit of Spiteful NN660 (Gary and I are digging that aircraft up) and used an Academy 1/72 Mk XIV fuselage and wings from a Magna Spiteful....anyways, to cut a long story short, I have managed to throw away the cowling bumps that go above each exhaust stack (part no. B16)....any ideas??!!! These bumps gave sufficient clearance to allow the Griffon cam covers to fit under the cowling!
