Simple Yet Effective
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.
Works Great
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.
18 mm Engine Retainers
Glad tha I ordered these retainer. I never have used them before. I like them more then engine hooks.
Great for new builds
Time to get rid of those pesky engine hooks with these retainers!
