Modification - S.W.A.T. Satellite Interceptor (Modification)


Contributed by Bill Eichelberger

Mod Estes SWATBrief:
1) Replaced the stock 24mm motor mount with a 3 x 18mm cluster.

2) Replaced the S.W.A.T. decals (!?) with upscaled Satellite Interceptor decals.

3) Two piece body tubes replaced by single length of BT-60

The cluster was built the old fashioned way: no motor retention clips. I glued three pieces of BT-20J together (with a heavy line of wood glue to seal the hole left in the center of the tubes,) then glued an engine block into one end of each. I then glued a CR-5060 to the top of the tubes, both to act as a centering ring and to seal off the three holes left around the outer edge of the tubes. When the glue on the completed mount was dry, I cut a slot into the outer edge of the centering ring and slipped a 36" length of Kevlar shock cord into the slot, knotting it behind the ring and securing it heavily with wood glue. When that was dry I ran a thick patch of wood glue all around the inside of the main body tube about 2" in.

I pulled the Kevlarback through the rear of one motor tube to keep it from getting glue on it, then slid the whole structure into the tube in one smooth motion to keep it from sticking. I left about 1/4" of the end of the motor tubes sticking out (just because I like the way it looks.) I then rotated the tube while looking in from the forward end and let the excess glue fill coat the centering ring and inside of the body tube to guard against any possible spots where the ejection charge could possibly escape. The tube was then stood straight up and allowed to dry.

The decal modifications were a bit less involved. I blew the original scans up by 1.67 and printed it out on two sheets of Bel Decal Paper. This was then coated with Testor's Decal finish.

Favorite Rockets: Goblin - now Moon Mutt or Silver Streak (twins)


Father of two boys

Both love the Museum of Flight

Purchased a Moon Mutt set from the gift shop and have been shooting rockets on regular basis

Used to do this with my father 30+ years ago and still have a Goblin, Starship Vega and Gemini Titan that we will introduce the boys to later. Right now trying to keep to mini moters. Found my old field box at my parents - including old launch systems,engines, wadding, repair supplies.

Model Rocket Building: Peter Alway Saturn IV Build, Part 1, Plans and Parts
This model was from Peter Alway's Home Page. I can't seem to find it now! If anybody has a link, let me know. The website had plenty of sport and scale plans including a Vostok, Saturn I and a Flying Rabbit that looks better than the old Estes Cloud Hopper. You can get Peter Alway's books: Rockets of the World HERE and Scale Bash HERE Both highly recommended! There's one model that has been on my "to-do" list for a while. The SATURN IV! This is Peter's "psuedo-scale" design of a Saturn that could have existed between the Saturn 1 and Saturn V, the Saturn IV. Full resolution plans aren't ...

Model Rocket Building: Estes Payloader II #3022 Build, Part 1 Parts
All the parts are standard and of good quality. For a while it was rare to find kits with clear payload section tubes. I'm glad to see they made a comeback. Part of interest: The laser cut fins didn't get cut all the way through the wood. While you should never just punch fins off the sheet, these will take a few passes with a sharp knife to free them.
