cluster

Inspiration In the days of yore, when reading G. Harry Stine's Handbook of Model Rocketry, an image toward the end of the chapter on staging struck me: The wheels in my head started spinning and couldn't be stopped. Pitchfork I built an Estes BT-50-based tractor parallel-staged model...

I'm planning on clustering 2 F Aerotech motors, does anyone have experience with this? The Firstfire's that are included say that they are not recommended for clustering motors.

I imagine someone has posed this idea before, and I know this would be a mess, but maybe a fun mess. I have an extra Estes Saturn V Skylab (main body tube is a bit squished), but the Skylab vs Apollo doesn't much matter here. What I want to do, because I can (try), is modify it to be a cluster...

Hi to everyone, I think is more than 5 years since I do not write on a forum, probably even more and I am so happy to finally have returned to this much effective way of communication (rather than social media ). I am writing and launching from Scotland UK, however, I am an adopted Scotsman...

Ok, as teased before, I am answering a challenge to upscale my 4" Splatnik. This will be a scratch built 12" diameter (roughly 1/2 sized) model of Sputnik 1. 3 engine cluster, streamer recovery. I'm going to post as I go. Step 1: Gather the parts.

Hi everyone! I have been developing a open source TVC system for model rocket. I then got a crazy Idea of clustering 9 motors. Of course I highly doubt I would attempt this anytime soon, But I was wondering if anyone ever clustered slow burn motors with normal motors. I made a rough CAD design...

Silly thought, but one I had in the shower earlier today. Is there any way to simulate parallel staging in a cluster? Specifically, I'm thinking of a situation where you'd have several very large motors strapped together in a cluster, and then only certain sets (in symmetrical pairs) would be...

One more entry from Boatgeek's House of Ridiculous Rockets. I wanted to build an LPR spool, and heck, what says fun like clusters, right? So out of foamboard and 18mm body tube came this guy: Unfortunately, when I glued it up two years ago, it was a little off-kilter. The plates of the spool...

So like a lot of other people who have the Saturn V they are looking to build/complete them for the up coming anniversary. And Estes has the newest re-release, which I might get and put in the closet where I had left this one. Me, well I think I got this kit in late 2010 (`DOH) and had started...

This one has a D12-0 booster that air-starts a two 18mm motor second stage (and an optional third stage, 18mm or 13mm). With the vent holes (see pics), it’s two for two on air starting both second stage motors. I wish I was a better artist - the paint job and decals leave much to be desired.

Hi! I’m new to the forum and would love any input, comments, and/or suggestions for improving my Rocket (my first scratch build). It has multiple configurations, including lifting/launching a glider at apogee. I would love to make it cooler! It is a two stage Rocket with an optional third...

I am building a linear-3 cluster rocket. The two side engines are 18mm (A/B/C) but the center is a single 24mm (D/E) motor. I only want the ejection charge on the center motor to fire. Are there any 18mm motors without a delay charge? (I know that the -0 motors don't have a delay charge, but I...
