Kits YOU Build!

Engine Adapters

Engine adapters are used to fly a smaller diameter engine in a model that has a larger size mount. The ASP 13/18 and 18/24 kits require construction and come with quick-change engine hooks.
The ASP 24/29 and 29/38 adapters are designed for friction fitting and require only very minor construction.
The Estes adapters are plastic and fit around the smaller size engines.
