Clone - Estes Battlestar Galactica Laser Torpedo (Scratch)


Construction Rating:
Flight Rating:
Overall Rating:

Contributed by Bill Eichelberger


The Laser Torpedo was essentially a shortened Photon Disruptor with different decals and a Wolverine nose.  Envisioning a fleet of Wolverines, I had bought several of the cones at NARCON from BMS, then found that the Wolverine didn't fly well enough to make a fleet.  Checking John Brohm's Estes nose cone reference, I found that I had the option of building a Teros or the Laser Torpedo with the orphaned cone, and since the Teros utilized white decals and chrome stickers, the choice of the Laser Torpedo was a pretty simple one.


  • 6.5" BT-20D engine tube
  • 7.75" BT-50H main body tube
  • BNC-50BC nose cone (BMS)
  • 2 AR-2050 centering rings (Semroc)
  • 3/32" basswood fin stock (Hobby Lobby)
  • 24" length Kevlar shock cord
  • 24" length 1/8" sewing elastic shock cord (Wal Mart sewing department)
  • small screw eye (Lowes)
  • medium snap swivel (Wal Mart fishing department)
  • LL-2B launch lug (Semroc)
  • 12" parachute (Estes)
  • decal (Bel Inkjet Decal Paper)
  • EB-520 engine block

SRP Crew

AKA: SRP Crew - Rockoon

Location: Earth, Solar System, Milky Way, Universe

Club Memberships: SRP

Favorite Rockets: Stretch Sandia Tomahawk and The Scratch Blue Bomber


I first launched a model rocket in 1980 with my younger brother. Fast forward to 2006 when both my sons got interested in rocketry, after they saw a Alpha III go up, we've made it a fun pastime together.

Yep, there's actually 3 of us doing rockets. We've decided to go with the team name SRP (Scratchbuilt Rocketry Program)

Therefore, we are know as the SRP Crew.

We run a website known as the Unofficial Rocktry Records Lists We needed to know how these rockets flew, and know details, like how high and for how long they go. (Altitude and Duration)

We fly when we get the urge and usually fly out at the family farm during the Spring and Fall when the crops aren't in yet.

We've flown over 200 rockets from 1/2A motors up to a experimental J motors.

Odd'l Rockets: SPUDNIK Flight Testing
I launched the SPUDNIK twice yesterday morning, both times with a A10-3t engine. Both flights were stable to about 100 feet but there was corkscrewing. The Odd'l Rockets Sputnik (with the 3" foam ball) flys vertical without any "coning" or corkscrewing. The problem is trying to drill out a straight 1/2" hole for the engine mount tube. If the line of thrust is off by a degree or two the rocket won't fly perfectly vertical. Add the uneven surfaces along the top and it probably won't fly without some spiraling. Drag and weight are other considerations. On both flights the model was nose down ...

Model Rocket Building: Estes Patriot Build #2056, Part 1, Parts
Everybody has built one of these, except me! This build will be a little different. At the bottom of each post I'll be keeping track of how long I take on each step. These are my personal build times, I tend to take longer on rocket building than most people. I don't keep track like this very often, it's a bigger effort to keep recorded build times. There will be upgrades. A BT-60 model at over 21" tall should probably be D engine capable. You can always drop in a 18mm adapter for smaller fields. A payload section will be made using the upper yellow tube section. All the parts: ...

Greg Smith's Blog: Der Red Mix mark II Skidfest at ROCTober 2014
After talking it up for over a year I finally flew my scratch-built Der Red Mix mark II on a full complement of seven burly Skidmark motors (as always switching to 720p in full-screen mode is the shit): A formidable liftoff featuring loud, flaming titanium granules: And notably angled ascent: I arrived at the lake bed later than I'd have preferred but the conditions were perfect all day with light, intermittent wind and perfectly clear skies. I had prepped all the electronics two months ago so I only needed to load up the seven Skidmark motors, set up the CD3 ejection system, mount the Flip ...
