Don’t know if you noticed a company on eBay selling Tango Papa decals. Company is cmrproducts_llc. and they have an eBay webstore. They offer mostly rocketry and model train decals. I noticed some of their decals that might enable some MMX rocket kits (or 13mm if you prefer). They have Estes Mini Bertha (BT-20), Estes Goblin 1/2 scale and my two favorites for MMX: Estes Alpha (BT-5) and Estes Phoenix (BT-20). For Phoenix lovers, they offer decals in BT-20, BT-60, BT-80 (standard), and 3 inch. I just finished an Ollie-OOP BT-50 based Phoenix, so I have to build a BT-20 based little sibling to go with it. Already have the standard BT-80 kit which I built years ago. They do offer a 3-inch Citation Patriot set as well if you are a fan of that kit.
