As long as nobody gets injured, I LIKE Prangs, Catos, and Explosions.
POWR-Prangs are the best.
Best way to guarantee a Powr-Prang is using a UPPER stage engine in the BOOSTER of a 2 stage rocket.


Excuse me, WHAT!!!!!!!!!!!!!

Thanks! If you decide to try and put together some wraps, let me know....I have a lot of dimensions worked out for MMX-sized wraps. I do most of my work in CorelDraw... I have scaled these up to BT-5 size to fly on mini motors as well. Vector graphics are a great way to go, you can trace the detail as large as you need to and then scale it down without quality loss.

As far as printing MMX cones... I have had mixed success. Most of the cones you see in that picture ate downscales of Doug Holverson's (sorry if that is a misspelling!) Centuri "5" series cones (from thingiverse). For whatever reason, sometimes I downscale a cone and it looks great in the slicer, but when I try to print it it starts mid-air instead of on the build plate. I still haven't figured out why that is yet. Also, with these small cones I find printing with a small layer height and using a raft helps. I mostly print in PLA.

Pretty sure GH was referencing my signature....a quote from Marvin the Martian

On that note, I have had many a Micromaxx CATO. They make a surprisingly loud POP! One CATOed so violently in blew a hole in the side of my Fliskits Stingray. More damage than I would expect from such small motors.

Thanks for the offer on the wraps. I have PhotoShop that I use so I'll see what I can do with that.
I have downscale some of the nose cones from Thingiverse and when I get to the size of a T-3 or T-2 tube the prints work and sometimes don't. Thanks again for the information.

Way back when, there was a 1/8th streamer duration event at NARAM. I made a minimum diameter and used dart (like dart board darts) fins as fins on my rockets. Easy to cut to size, thin and just needed some CA.

I thought a company in Alabama named Luna Tech INC made the MMX. Quest just probably orders up a batch here and there. I wish they would come out with no-thrust smokey MMX and 13mm like the old MRC FX . Colored smoke!

I can't confirm this, but I think Luna Tech is where the FX motors were made, though since the motors were made in Germany, maybe the FX's were too. I was under the impression that both types of MMX were made in Germany. I know the Type 2 (fish paper casing) were made there. I'm looking at a few packs I bought recently at a firesale, and the package says "Motors made in Germany. Igniters made in China".


Tangentially, at that same firesale I bought a few packs of Q2G2 igniters, and just missed "by THAT much!" getting three bulk packs of Chinese Quest C motors, for $5 each!! 75 motors (and their Q2G2's) for $15. Oh well. As it was, I cleaned up on Estes A8-3s made in 2012 for a buck a pack.

Thirty-three packs at 1972 prices! I can just toss them out like candy to kids at launches. If it ever quits raining on our launch days.

I see a lot of builders of Micro Maxx use super glue more these days. That's something I will have to try to master.


I just bought a pack of Quest Micro Maxx kits that are basic tube, three fins, and a nose cone (where the nosecone is a repurposed ear plug (the soft pliable foam you stuff in your ear at concerts or in loud factories). No recovery system, like a real Nerf rocket! The kit is called the Boingo. From 2012 or so.

we've been told over and over again that Quest has a nearly inexhaustible supply of these at current use rates. To paraphrase Jay Leno, "launch all you want. We don't need to make more."
