Default centuri lectra-line 1 or 2 launch controller

Looking for a centuri lectra-line 1 or 2 launch controller regardless if it works. Just need a good body and hopefully a key.

I was hoping to use one of these as a model for cloning 3D printer parts for everyone.

Maybe someone will come forward?

Thank you!

If I had one I would loan it for this purpose but the LL-2 I had years ago was pitched when it failed.
Sorry.

Hi Flash,

I'm in the process of going through my collection to clean things up in the basement. I've got both the orange and black controllers somewhere down there. I'll let you know when I come across them.

In the meantime, are you interested in 3D modeling the MPC Lunar-Lectric Launch Controller?

Awesome!
To tell you the truth, I've got another person that I'm going to be getting with on the actual modeling. If one was found, I was going to ask Jack Hydrazine

MPC Sounds good! I'll ask.

So, any updates on the MPC controller ?

I was trying to get Jack Hydrazine to do these for us. He ended up moving and never heard back on anything and I never followed up either. I would recommend contacting him direct.

I was really hoping to get him to do the Centuri one to.

Contact Annette Sostarich, the "Space Crafter" (as her Ebay Store is called, see: https://www.ebay.com/str/spacecraft...57.m570.l113337 ). She has an aerospace ^and^ a model rocketry background, and she has 3D printed numerous nose cones, fin units, and other things (including cabinets for crystal radios, just from my descriptions!) for me, and:

She also came up with an innovation, which works equally as well with Estes BT-5/Centuri #5 & MPC T15 nose cones as it did for the large, Centuri PNC-132 and PNC-160 nose cones, which each had a molded-into-the-base [which was pre-glued] "tie-cross" (see: http://www.ninfinger.org/rockets/no...a/72cen060.html ). By 3D printing nose cones--of *any* size--with this tie-cross 'printed-in,' the one-piece, hollow nose cones can, without any modification, be used in streamer & parachute recovery models (and boost-glider "pop-pods"), and in motor-ejecting models (such as the Estes Streak, Centuri Li'l Herc, Centuri X-24 "Bug," etc.). ALSO:

Annette could 3D print high-fidelity duplicates of old launch controllers such as the Centuri Lectra-Line ones, the MPC Lunar-Lectric "pistol grip" one, the Estes FS-5 and Solar Launch Controllers, etc. PLUS:

I'm also sure she could 3D print--perhaps in multiple, to-be-glued-together parts, depending on her 3D printer's "workspace volume"--launch pads, such as the Centuri Servo-Launcher (see: http://www.ninfinger.org/rockets/no...a/72cen052.html ). Because the Servo-Launcher had extremely short--six inches or so?--battery-to-igniter leads (and thus had very little voltage drop along them; and it was designed for the old "cut-apart," rolled-up nichrome wire igniters with the "flame-paste booster propellant" on the wire every three inches or so, that being the "pre-Solar Igniter" era), it could fire the old igniters using only ^two^--not four--"Photo-Flash" D batteries. With today's improved igniters and improved dry-cell battery chemistry (alkaline, lithium, NiMH rechargeable, etc.), two of these modern D batteries could probably ignite clustered motors, if used in a Servo-Launcher. And incidentally:

Pneumatically-activated launchers or this type are used for firing wire-trailing rockets for lightning-attracting experiments, because there are no conductive igniter wire leads that the lightning can flow down, to fry the experimenters. At least one such NOAA and/or university experiment (or experiment series) used AeroTech rockets (either Arreaux or Mustang kits), fired using a pneumatic launch controller, to trail very thin copper wire aloft (the lightning strikes always vaporize the wires). So if you ever want to conduct a re-enactment of Elijah calling fire down from Heaven, this is an easy--if a bit hazardous, but certainly spectacular!--way to do it. :-) (...sees--in his equine mind's eye--GH going out to buy a big roll of thin-gauge enameled magnet wire...).
