Recently, I have been building the Semroc Mars Lander. It's a well-designed kit (well, reproduction of a kit) and most of it makes sense. However, I've arrived at a step that I'm having a lot of trouble with, and nobody else seems to be having this problem. The step that is giving me trouble is...

It’s a custom built BT-55 rocket.

I am building a 3-stage model rocket that goes D-C-C. However, I am confused about how to arrange the motor mounts. Could someone please post a diagram or something of how to do this? Thanks!

Had to rip out faulty shock cord mounts from my minimum diameter rocket... *twice*...

Ripped off a wrong-sized launch lug from a minimum-diameter rocket, and some of the body tube in the process.

When I was five, my dad took me out to a launch. Many years later, I was browsing the web, looking at videogame pictures, and I found someone who had made a model rocket based off of the videogame. Then, I remembered the launch, and decided that I HAD to get back into model rocketry. The result...

Sorry, GTG to LUNAR. Hopefully no RUDs or CATOs!!!

I am using an Estes BT-20 body tube.

So, I have this one idea for a rocket I want to build. The only problem is, I want it to be staged, but the motors aren't next to each other. In fact, they will be 18 inches apart. (length of Estes a la carte body tubes) Is it possible to stage them without electronics?

When you spend more time drooling over model rockets than you do working on your Spanish project.

When put off practicing your instruments until later so you can "just add a few touch-ups"

Yes, the orange coupler tubes are the ones I mean. Thanks for helping!

I have a 24mm motor mount that is 95mm long. How can I add the 25mm adapter when using D12 and C11 motors (which are 70mm long) but remove it when using E9 motors (which are 95mm long)

Finished quite a few rockets today. W00T!!!

I didn't know that there was a Bay Area Rocketry club! Where can I join?

Added another fin to my 2-stager, Romulus. Here's my fleet: My Fleet by TeslaPenguin1 posted Oct 1, 2018 at 10:41 AM

Pics of my Rockets

Bought some T motors for my mini-rockets. As well as some larger motors for my payload rockets.
