set includes a pair of corrected exhausts for the Revell Super Hornet Kits. This set corrects the exhaust feathers, which should be at an angle instead of straight, and the depth of the exhaust tube. These are a drop fit replacement, that only requires you to enlarge the hole on the rear of the fuselage.
You can see how the incorrect "straight" petals on the kit nozzle are wrong compared to the angled petals of the RR part..
Here you can see that the assembled exhausts do not interfere with the stabilizer mechanism.
