Medallion Models 1/48 P-51 Flaps
By Matt Bittner
Originally designed for the Monogram 1/48 P-51 the instructions state they can be used with any other kit as well. If you're looking to display your 1/48 P-51 with dropped flaps than it should be as easy as cutting away the kit-provided flaps and adding these in their place.
If you're not using these with the Monogram kit then you should definitely measure and cut appropriately.
A definite "thanks" to Starfighter Decals for not only re-releasing these older, resin sets, but also for sending them in for review.
