  L1 build thread
Posted by: IndianaSteve - 2 hours ago - Forum: High Power - No Replies

Well the time has finally come! It is time to build the rocket I will attempt my L1 certification with. My rocket of choice is the Madcow 4” Little John with a 38mm motor mount.

 I am going to attempt to do my first build thread here so bear with me  Big Grin 

[Image: TlCri5.jpg]

Parts that came in the kit are pretty straight forward, and seem to be of good quality. 1/4” plywood fins and centering rings, heavy eyebolt and rail buttons and a 38mm motor mount. This is the first Madcow kit I have purchased and am pleased with the quality of parts that are included.

I did purchase a couple extra parts to use in the build. A aero pack engine retainer and a Loc engine adapter so I can use some of my 29mm hardware for test flights. 
Stay tuned for construction updates!

  Der Saturn Max
Posted by: Trident - 04-13-2018, 01:20 AM - Forum: Your Projects - Replies (1)

My latest project, the little known, never photographed until now, secret German moon rocket ...

Der Saturn Max

It’s been getting roll patterns over the past few days, and just needs the mid-body roll pattern.  Typical “Max” decals to be added in the next few weeks.  I must determine the size I want and contact Mr. Stickershock.

This one has the standard 24 mm motor mount, but will fly on the F24 White Lightning 24/40 RMS.

  Math behind a suicide burn
Posted by: gereshes - 04-02-2018, 08:35 AM - Forum: Rocketry-Related - Replies (1)

Hey,

I'm currently writing a two post series about the math behind a suicide burn. The first part, which can be found here and is up now, goes over the system dynamics and works on simulating the system in Matlab. Part two, which drops next week Monday, focuses more on the analytical math behind suicide burns.

Let me know what you think!

Thank you,
Ari

Saw this at erockets today:

http://www.erockets.biz/semroc-flying-mo...ro-kmx-06/

Nice to see a new MMX kit being introduced.

EDIT: The link is no longer working, looks like the page was deleted. Maybe someone spilled the beans too soon at erockets. But it's a MMX scaled Blue Bird Zero. On TRF, it was mentioned that four MMX kits are forthcoming. Woo hoo!

Update: 4 new kits are the BBZ, Goblin, Fat Boy, and the Hawk.

Has anyone flying a Bull Pup with a D10-7 motor?
I've flown mine many times with a C6-7, but I'd like to get a little more altitude!
Any issues? Thanks Smile!!

Just found this forum this so morning so.......
I became a B.A.R. 9 years ago, and haven't looked back!! I Launched my first rocket, an Estes K#11 Wac Corporal in 1968...yep! Im OLD Big Grin !!
Its almost sickening how many rockets ive built in the last 9 years, and I enjoy every second of it! I fly mainly low power with some mid power thrown in....
the biggest motor ive used is a G80 in an Estes Leviathon..BEAUTIFUL flying model!! I do fly a lot of D powered stuff including some 188mm to 24mm conversions....im currently building a Rocketarium Little John for my Great Grandson as his 2nd rocket...he is only7, and not quite ready for the building part yet, but he loves to see them FLY!! Gonna try to post a few pics here! Have a GREAT DAY Smile Smile !
