29mm Model Rocket Motor Retainer Set

These are the same retainers that come in Estes Pro Series II kits. They work well for scratch built rockets or kits where you would not want to invest in an aeropack retainer, but provide the benefits of a screw on. The only downside is that they are plastic so they can be more easily effected exhaust heat discoloring the cap. Overall they are an excellent value.

Estes has hit the nail on the head with these retainers. If you're building any 29mm rocket available on Hobbylinc, add these to your cart. You will be glad that you did! These retainers are perfect for Single Use and RMS motors from Aerotech, as well as the common Cesaroni motors. These are comparable to the much more expensive Aeropack motor retainers, except a little more bulky and not quite as slick as the aluminum Aeropack. The functionality is identical, as these retainers will work just as well and you get 2 at a much lower price. Add this to any LOC or Aerotech kit with a 29mm motor mount! Makes your life a lot easier!

I started out using these on some of my larger Estes rockets because they were included in the kit, but I quickly ordered some extras when I realized the utility that they offered. Just scuff up the inside of the ring and the end of the motor tube, apply epoxy sparingly, and wait until it dries.
