These adapters let you fly a mini 13mm engine in a rocket built for a standard 18mm engine mount, so you're not limited to one engine size per airframe. A rocket that normally flies on an A8-3 can be flown on an A10-3T instead, which is useful for smaller fields, lighter rockets, or simply getting more use out of mini engines you already have.

Fitting takes two steps and no tools: slide the mini engine into the adapter, then slide the adapter into your rocket's engine mount. Each adapter is reusable flight after flight, and the pack of three means you can leave one in each rocket or keep spares in the range box.
