Thrust ring question
I bought one of the new Estes Pro Series rockets, the Leviathan, and it shows that the thrust ring is optional. Should I use it, and if so, how deep?

If you leave it out, you have the option to use different size/power motors. If you know for certain you will only use one size motor, glue it in at the depth for that particular motor. Otherwise, leave it out. Some single use motors have a thrust ring molded into them at the nozzle end. If your motor doesn't have it molded in, use tape to make a thrust ring.

If it is optional, did they mention how to use motors of indefinite/longer length?
To me it is almost entirely a UI issue. Jerry Last edited by Jerry Irvine : 04-01-2012 at 08:56 PM. |

The rocket comes with a screw on cap to keep the motor from ejecting. I guess you friction fit it as a thrust ring?

As I said, some motors have a thrust ring molded into them. If they don't, you use tape to make a thrust ring. There's no need for friction fitting because the kit has a retaining cap. Friction fitting would only be needed if you can't use the cap. Here's what I mean for a tape thrust ring. It's from one of Doug's posts.

I sometimes get tired of posting this since 1984, after the internet 1994, after the web 2000. Okay maybe I just get tired. Jerry |

I understand but don't see how I could do that and use the retaining cap

My guess? 3/8" tall x 1/32" thick. Lottery ticket? |

You won't need to do that with the motors Estes wants you to use in the rockets. They have molded thrust rings and will fit with the cap.
