Clone build: Estes mini scale combo pak #0874

[kuririn]

Rummaging through my build piles again while the paint dries on my other builds.
Amazing the projects you find that you bagged the parts for and completely forgot.
Anyhoo, this kit included two mini powered rockets, the IQSY Tomahawk and the Exocet MM38 missile.
I will be doing clones using parts from erockets and the plans from JimZ's.
Parts:

Tubes, thrust rings, nose cones, and laser cut fiber fins from erockets.
Got the fins when dinosaurs ruled the earth, so don't know if they're still available.
Shock cord will be kevlar anchored to the thrust ring.
Original had rubber shock cords anchored to the airframe with two slits, with a paper cover.
How nostalgic. Brings back memories of my first kits.
But unsightly.
No chutes or streamers. Recovery is mid blow break apart.
Couplers from my stash.
Decals from the scans at JimZ's, modified on white paper with a black background.
Only the Exocet has decals.
This should be a fast build.
TBC.
EDIT: I re-read the instructions. This will be nose blow break apart, so I don't need to couple a 5" and 3" tube together. I'll just use an 8" tube instead. KISS.
Laters.

Fins are on.
An outside notch was cut on the thrust rings for the kevlar loop.




Good night.

 

[kuririn]

Launch lugs were glued on and everything got filleted and left to dry overnight.


Kevlar was tied to the thrust ring and ring was glued into the body tube.
Screw eyes were glued to the nose cones (except the Exocet which needs two washers for nose ballast). Need to run down to Home Depot.
Kevlar shock cords were tied and glued to the screw eyes.


Assembly is done.


Will update when paint and decals are on.

Aerodynamically, is there a difference between having the fore and aft fins in line or not?

Holy Frijoles you have a bunch of rockets!

Holy Frijoles you have a bunch of rockets!

And he's building at a pace of just about 5 per week right now, so....

 

[kuririn]

Maybe I should change it up and do a big MPR rocket next.
Instead of the mini, micro and cardstock stuff.
We'll see.

Someone has to defend us from the NK.

IDK, maybe less drag if they're in line?
But I think the engineers at Aerospatiale probably had a good reason(s) for doing that.

That's what these are for:

The old missile battery next to Makakilo...

They are coming along nicely!

 

[kuririn]

IQSY Tomahawk and Exocet MM38 are done.

I may print a small decal for the Exocet.
Or not.

Seeing even these "simple" builds I discover that my masking techniques....suck. Practice, Practice I guess.

 

[kuririn]

Added on a couple of home printed decals to the Exocet.

Well done - they turned out great!
