Madcow Momba Build - In Pictures

I've been working (slowly) on this Momba build since the end of January, due to eating up my rocketry budget with a few unplanned (read: impulse) purchases.

Anyhoot, I've bee taking pictures along the way but skipped a lot of the basic stuff.

Note: not all the pics follow the build chronologically due to "10 attachment limit per post". Sigh...


The plan (Needs updating)


The goal!



Nose cone mods for adjustable ballast.

Airframe ready for fins


JB Weld + Estes Fin Jig FTW!

Forgot to take pics of the Aeropoxy internal fillets before attaching rear CR.


First time ever for external epoxy fillets. Turned out fairly well.


Rust-Oleum - Chevy Red-Orange p/n: 248947
Krylon: Blue/Gray p/n: 1625

Gotta wait till things warm up outside....

I had time on Wednesday afternoon to apply 2nd coat of primer on the Momba and Big Daddy.

Had some time yesterday to get more color on the Momba

Getting close.....

1st Coat


2nd Coat for NC

Made more progress last Friday.

Final coat on NC. Applied Frosted Pearl Clear to add a little character.




2nd coat on airframe.

Decided today that the Momba does not need another coat of paint.



Now I just have to work up the nerve to spray the decals. I'm nervous because I'm not really good at detail work, but it will happen regardless.

What did you use inside the BT to secure the upper airfoiled rail button so that it doesn't mess with the laundry?

I used a "T-Nut"



I used a pair of needle nose pliers to remove the prongs, wiped it down with some isopropyl alcohol and sanded both sides of the flange with 100 grit to give the epoxy something to grab. I also had to shorten the rail's screw a bit. Used a Dremel with an emery cut-off wheel for that.
