Pro Series II™ 29 mm Motor Retainer Set

I install an Estes motor retainer whenever possible. Taping engines to a paperboard tube eventually wears out the tube on frequently flown models. Retainers add life to such models!

Thank you for the spare parts they are very helpful and I can always use them to make repairs if need to be thank you so much for this wonderful product and I would recommend Estes to anybody.

Again, just what I needed.
