First MMX Post!
#1
I just wanted to be the first (before the MMX discussion is taken over!) Tongue
I'm also testing out the photo posting.

These three are prepped and ready for the next schoolyard launch.
From top to bottom are the 
Fliskits Crayon, Applewhite Bic Pen and the Quest No Mercy.
All three are great MMX performers.

I was going to try to beat you for the first! Nah just kidding.
Nice birds.
I'm looking forward to playing with some MMX downscales.
The motors are not readily available here in Oz, but there is enough interest in an Aussie forum that a local retailer has confirmed he will be placing an order in the next few months. I just have to learn to be patient   Dodgy

They all look great ,especially the Bic pen hcmbanjo!
What kind of altitude do you get from these, and are they tumble/streamer recovery?
I haven't tried this end of the spectrum yet but think I should!

Hi Viking,
Stop by my blog, I have quite a few downscales for MMX and T engine models.
Most are cardstock fins and a paper wrap that goes around a BT-5.

Hi Greg,
The Bic pen is an Art Applewhite freebie:
http://www.artapplewhite.com/aksjdf/bic.pdf
Stop by his website, lots of great saucers and monocopters in most all size engines.

On the Bic pen (and the two other shown) you can get 80 - 100 feet.
Best altitude results when you keep to the simpler 3FNC styles. 
They are small so they look like they are going much higher.
Recovery - Most have a small streamer but nose blow is easier and works well.
These are very fast off the launcher and you can lose sight of them. A streamer helps to find them in the air and on the ground.

My only problem with them is the short delay, less than 1 second.
They are fun as a first flight of the day, to test out your equipment.
There is no pyrogen on the bare nichrome igniters so you have to hold the launch button down for an extra second.

Last tip - 
The FlisKit MMX models are great and good performers. My Fliskit Honest John is a personal favorite and gets launched often.
The Quest plastic RTF models can be heavy, draggy and unstable.
The Quest plastic saucer gets 10 - 15 feet up. You could throw it that high.

Thanks, and apologies, I never made the connection.
It was your blog and the Astro 1 and your Patriot that got me on my quest(sorry) for MMX motors!

Thanks much hcmbanjo!
Does your Bic pen have a cemented NC as in Art's plan, or did you put in a small shock cord/thread to allow for nose blow recovery?
Even substituting a toothpick, I am a little concerned about a lawn dart type of recovery (perhaps into someone's eye with folks looking up to try to spot it on its return).
Not having flown any this small, I am not sure how easy it will be to spot in coming back down , especially if streamlining in.. Undecided

Hi Greg,
The pen point is glued in, I didn't use a toothpick. There is just a little ink left in the point, I can fill out a flight card, then fly the same pen.
An inch back from that the pen body is cut, a small dowel was used as a coupler. Imagine a small, useless payload section.
This one just has a length of Kevlar for a shock cord with a small streamer.

I haven't had any problems with ejection of the streamer. 
I'd be more concerned about a bigger, heavier rocket coming in hot.
These things are pretty light. If the nose cone comes off it won't streamline in.
You do want to use a streamer, it helps to find it.

I'll be following this thread for sure.  I've been away from rocketry for a couple years (but received an email from YORF about an old thread I was subscribed to, and then I found the announcment of this new forum).

Seems like retirement has me working on WAY too many home remodeling projects.  We have two grand daughters that I want to introduce to model rocketry, and this looks like a good avenue to pursue.  It is difficult to find places close by to fly standard model rockets, but MMX opens up a lot of possibilities.

Hi Trident,
A few things to note if you are getting into MMX rockets;

Many of the original Quest plastic RTF MMX rockets are not great right out of the box.
The RTF Quest No Mercy and Critical Mass fly well but the streamer "pistons" rarely eject properly.
You'll see them on Ebay with the "Silo" launcher but I don't recommend those starter sets. 

Here's a flight report from a few years ago:
http://modelrocketbuilding.blogspot.com/...82010.html

Instead of the old Silo design, Quest does sell a MMX launcher. 
It's their regular tripod launcher with an smaller diameter MMX rod adapter.

For a better MMX experience, check out the FlisKits, ASP and Leading Edge kits.
