Frequently Asked Questions about the 29mm Estes Retainer
Q: How do you pick the right size motor retainer?
A: Watch the video below that describes the process.
Q: My kit has an engine hook. Can I use these engine retainers with this kit too?
A: Yes. But you have to remove the engine hook and the thrust ring from the kit. If the kit hasn't been constructed yet, it is easy to do. Watch the video above that describes the process.
Q: Do these engine retainers work with "single use" motors too?
A: Yes they do!
Q: Does the Aeropack 24/29mm adapter work with the Estes 29mm retainer?
A: Unfortunately, no. The ring on the Aeropack 24/29mm adapter is too large to fit into the 29mm Estes retainer screw-on cap.
