Among the numerous update sets Phase Hangar has produced for the Hobby Boss kit comes this exterior upgrade that includes replacement wing tips and tail cone. Covered chaff dispensers are featured under these wing tips as well as missile launch detectors. These parts also spare you the chore of closing the joint in the curved underside of the wing present on the kit molding.
In addition, this set includes a replacement tail cone with updated detectors in place. Both parts require plastic removal from the base kit. Both fall on panel lines so you have a guide for cutting. The only caution I would note is squaring up the wing end on the kit part to make sure the new wing tip is positioned correctly.
There is also a second exterior upgrade set (#48110) that includes antennas and gun muzzle. If you wish to have open wingtip Flare/Chaff dispensers, you can order set #48109.
