Adapts standard engine mounts to hold a mini engine. Two simple steps transform a mini engine into a standard size one. Rockets weighing up to 60 grams that would normally fly on A8-3 engines can be flown on A10-3T engines.

How to use it: Insert a standard engine into the adapter, and insert the adapter into a rocket.

NOTE: This motor adapter has been tested in products that use ESTES metal engine hooks. It may not work with other brands of engine hooks.
