    My curiosity's been piqued...

    Can anyone direct me to a good website for basics about MicroMaxx rockets? The only links I've gotten when googled are for hobby stores wanting to sell prefab ready-to-fly sets. We want information...

    ASP Aerospace Specialty Products. Has at least 5 Micro-Maxx Scale kits. ranging for 7 to 12 bucks as I recall.
    www.asp-rocketry.com
    Art Applewhite offers a few saucers for Micro-Maxx.
    www.artapplewhite.com
    QCR: offers about 8 different competition type Micro-Maxx models. http://cybertravelog.com/qcr/
    and of coarse Fliskits. Offers a few micro-kits some of which are free! http://fliskits.com

    If you need plans, or other material Please visit the Micro-Maxx yahoo group. We now have at least 55 one page plans and at least that many photos of mostly scratch built Micro-models in ever category you can think of! The site is loaded with just about anything you may need concerning Micro-Maxx.

    graylensman,

    I highly recommend you build your own using parts from places like ASP. Also note that you can turn your own nosecones fast with a drill and wood dowel for material. If you do wish to try a starter kit, some of them actually fly well. The three and four fin basic models like the Quest Vector, Raw Fusion, Critical Mass and No Mercy actually fly pretty well.

    Also, you may want to do a search for MicroMaxx at our forum right here...there is a wealth of knowlege regarding designing, building and launching MicroMaxx models that has been posted...you will spend hours looking and reading. They are a blast and the kids and I have no problem burning up a ton of motors in one sitting.

    Keep us posted on your first MMX project and welcome to the forum! :)

    Carl

    Everything those guys said is right on.

    DO NOT buy the Micro Maxx Saturn V except for display!

    It only flys about 8'....on a good day!

    Hey, mine flew to at least 15' once!

    Before it broke the tower off on the asphalt.... stupid wind...

    :D

    The RTF models from Quest are nice for display. The tomahawk flies reasonably well. They do make great pieces for your desk at work. :D

    We have had one micromax rocket that being the SR-71. It didn't fly bad, but for some reason the little streamer wouldn't un wind. It came in on its nose and broke it off. I built a couple little rockets to use the rest of the motors up we had, but now my problem is I can't get them to ignite. Tried new batteries, cleaned the contacts, and still no flame on. Any suggestions:confused: :confused: .........Larry

    Don't bother with the Quest igniter.

    Get a good 12v or larger system...a lot more "punch"

    OK, if I use 12v what igniters should I use? Those nozzles are to small for anything else. Would a small piece of wire work? Thanks......Larry

    Larry,

    Use the igniters that come with the MicroMaxx motors.

    Here is a little trick!

    Crush up some pyrogen (match heads work) and mix them with a little clear model airplane dope. Then dip the MicroMaxx igniter into the mix so you get a little bit on the tip.

    Just a little!

    Works!

    I use the stock igniters with the plastic shell removed, and a 12v controller. Hey, why not use what comes with the motors? Pyrogen isn't really necessary unless you are clustering and want to hedge your bets. I have never had one of these fail when hit with 12v. I have broken a couple during the extraction process. You can also use Estes igniters if you have extras, but you have to pick those that don't have much pyrogen.

    If you want to continue using the 9v system, go the the Yahoo group and look around for battery discussion. Micromister tested a bunch and found one that worked far better than the others. I think it was the Energizer E^2 titanium IIRC. If you don't find it, I'm sure he will respond also. As you mentioned, make sure you keep the internal contacts clean.

    Bare nichome wire works just fine, keep it under 2" long. 30ga has proven to work best. I've see anything that will Heat work for single motors, even a single stands of copper wire from an old extension cord. Keep them short under 1" and use a 12 volt system with plain old everyday micro clips like this or something similar. If you want to use and Quest mmx igniters just bend the bottom wire hooks enought to get a micro clip on them and your set.

    the streamers really don't unwind from the piston, I've found if you want them to work most of the time, fold the streamer back on itself, half the length each time until it will only have a half warp or so around the piston. Sort of like folding a competition streamer.

    If your going to stay with 9V the energizer E2 is the only way to go. the stats are listed in the files section on the micro-maxx group.
    another very easy way to convert your 9v quest contorller is a simple drop cord soldered to an old 9v batter top. heres a pic that might help. a complete conversion explaination and pictorial is listed in the files setion of the micro-maxx yahoo group

    I made up the pyrogen mix for my Nike Hurc. 4 engine cluster...I made a lot more than I needed so I did the rest of my igniters...waste not want not!

    Just use a little on each. Just enough to fill UNDER the bend in the igniter. Try not to get too much on the outside or it won't fit.

    THANKS guys for all the help. I'm going to try your suggestions. My SR-71 is history, but I have a couple I built so I'll give things a try........Larry

    My SR-71 did the same thing.

    If you can find the NC for it, just use some CyA and glue it on permanently. I used an x-acto knife to drill a small vent hole just in front of the motor area for ejection gases.

    Works just fine. Just keep your eyes open when you launch it and make sure the dirt is soft. ;)

    Also did that with one of my Tomahawk MMX birds, but it already had the vent hole.

    I just found Totally Tubular, now has a website www.totubular.com
    He is now stocking some micro maxx glider kits from Edmonds Aerospace, a micro delti and a micro IVEE as well as all the tubes, rings couplers, recovery materials, adhesives,kevlar, Etc. you could want, check em out.

    Yeap ya missed something!
    I just looked at the web site. it's the 99 price list. I just placed an order with Jim, He e-mailed me a catalog updated 07-13-03 that lists the kits, and a bunch of other stuff not on the 99 list.

    Well I finally had success with the Micro-Maxx. I used the igniters that came with the motors, but took them apart and hooked them to micro clips and 12V worked great. Had four good launches with my Micro Rag 1. Thanks all...I think I'll build a few more rockets to go with these motors............Larry

    Oh, Sorry....no launch pictures. I'm just not fast enough with the digital camera:kill:

    I'd Post it here but I can't get the darn thing to download from my e-mail!!! The order is so small I'm sure he'll just stick it in a box. 100 CR 2+-3f MMX to T-3 .375" centering rings and a 1/8" carbon fiber rod.

    Congrat Larry!
    May all your micro flying be as easy and fun. 10/4 on the digital launch pics are these little buggers quick or what!

    Okay, I've spent a couple of days digging up info for getting started on MMX. I gather that I can use my current launch controller - an Estes 4AA unit. I found plans for a launch pad on Art Applewhite's site. He's got a parts list that includes everything except a black box with a little red triangular protuberance on top. What is this thing??

    Looks to me to be the flame on a remore controlled butane lighter which is used in lieu of an igniter? :rolleyes:

    You can wait for art to reply or email him direct.

    i beleive that is supposed to represent the tip of the ignitor... If you look closely at the bottom of the ignitor, you will see that the two ignitor leads are the same orange color.

    I agree with Jim. The MMX igniters look just like that. and the bottom does look alot like leads for the igniter

    If you have the Quest motors and igniters in hand look at one of the igniters.
    Art was trying to depict a Quest igniter instelled (clamped) in one of the two cloths pins. As Jim said the orange it the Nichrome parts of the igniter. the Black is the black plastic holder.
