29mm Model Rocket Motor Retainer Set

Easy to install and easy to use. This is a good retainer for the price and an excellent alternative to the more expensive metal retainers which can cost as much or more than the rocket they are used on. After a few launches of E-G class motors, my first pair are holding up well. My only nit is that it is a bit bulky. On smaller diameter rockets, the closure is larger than the rocket. On one use, I sanded down the ribs to make the model a bit more aerodynamic. I just bought two more packs and plan to use these on all my 29mm motor mounts.

Love the low cost for these easy to install/easy to use retainers. Not only are they cheaper than the metal alternatives but you get two sets for less then the cost of a potentially difficult to use metal models (older versions used little snap rings that were a pain to install and remove...and easy to lose!)

I purchased these after I misplaced the original in the Estes Ventris kit. I can not be more satisfied. These are cheap, and work great. Simply epoxy one end to your motor tube, and you are ready to go. They screw on, and hold your motor tight. I launched my rocket, and these survived a 1,000 feet free fall, keeping the motor in nice and tight. Great product, and is a must have for any rocket, its price, simplicity, and functionality make it such a great product.
