Great & inexpensive motor retainers! I’ve used them on 3 scratch builds and they secure the engines very well and make it easy to install and remove an engine.

This is a great accessory to use, especially when scratch building…..very inexpensive yet durable….You get TWO Estes retainers for less than the price of ONE of the competitors retainer. Thank-you Estes.

This is a product that has long been needed in our hobby. Sure there are other 24mm engine retainers out there but their price puts them out of he reach of the average modeler. These provide great retention at an easily affordable price. Thanks, Estes!

I’m sure glad they came up with these. A cheap effective alternative to the ridiculously expensive retainers from other companies.

Just like the 29mm, a great value. I bought a bunch and converted many of my 24mm rockets.
