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!
