Works Great
By: Rocketman (Lebanon)
I have 2 rockets with this on. I never had any problems for either of them one had 12 launches into it and the other one had 3.
Simple Yet Effective
By: Mr. Northport (Northport, WA)
I really like these retainer ring setups as they make engine mounts simpler to put together. They also look better cosmetically, better finished look, as you don't have the middle finger sticking out of the end. It also makes it far easier to build two stage rockets.
