"Great value!"
isobig (PA)
These are the best value for a 29mm motor retainer. MUCH lower cost than the metal retainers and work just the same. They are easy to attach and use. After many flights they hold up very well. I highly recommend these! I wish Estes would make these in other sizes.

"Outstanding product at a great price!"
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!

"Best economy engine mount for 29mm"

I love the simplicity of this retainer. The price is great and installation / use is a breeze. I will never fumble eith any other type of retention system for my 29mm RMS loads.

"Good retainer for price, a bit bulky"
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.
