Custom Rockets - Matra {Kit} (10018)

Manufacturer:Custom Rockets

Construction Rating:
Flight Rating:
Overall Rating:

Contributed by Bill Eichelberger


The Custom Matra is a cool faux-missile rocket with a difference that might not have been completely obvious to anyone checking out the picture in the catalog back in 1994-95.  It has seven fins, set in a four on the bottom, three on the top pattern.  While I doubt that this oddity would detract from the rockets performance, it would never sit well in my mind, so I had a decision to make.  Would my Matra be an eight fin rocket or a six fin rocket?  Simple decision, really.  


  • PNC-60 nose cone
  • 18" BT-60 main body tube
  • 6" BT-60 upper body tube
  • 9" BT-50 transition body tube
  • 3/32" die-crunch balsa fin stock
  • BT-50 engine mount (from Estes Vagabond donor)
  • decal
  • 5060 centering rings (6)

Model Rocket Building: Carded Red Max Build, Part 1, Parts
I've seen a few pictures of "Rocket Families" on the forums. The Red Max is a favorite with the Estes Mini Max (BT-50 based), standard Red Max (BT-60 based) and Mega Red Max. Well, how about a smaller BT-5 version for 13mm engines? This one is tiny at just 5 1/4" tall! It performs like a BT-5 Mosquito. At one time I had a little carded Red Max model. It was a BT-5 diameter with a Micro Max engine mount. I lost it somewhere along the way and wanted to make another one. After a few searches I couldn't find it. I thought it might be at Wayne Hill's Rocketry Blog - CLICK HERE There are many ...

Model Rocket Building: Goony X-15, Part 1, Parts
In the past I bought a few of the Quest X-15 Parts packs. In the pack you get everything except the engine mount, main body tube and parachute. I figured with some BT-60 based parts I could make a good goony version. I raided the spare parts drawers. I found an Alpha style nose cone and a length of BT-60. I think the main reason people buy the X-15 parts pack is for the decal sheet. It is a water slide sheet with lots of white decals on it.

Rocket N00b: North Coast Rocketry SA-14 Archer - Unboxing
I recently received a little gift - one of the rockets on my wish list - from Matt Steele, of North Coast Rocketry . North Coast, who make mid power rocket kits and some accessories, is a sponsor of The Rocketry Show podcast, and as part of that sponsorship, Matt sent us some rockets to try out. I've had my eye on an SA-14 Archer for a long time. I'm doing a video build series on The Rocketry Show's YouTube channel . I started with the following unboxing video. I'm uploading the first build video later tonight, once I'm done editing. Here's the first video. Follow me on Twitter . Like my ...

Model Rocket Building: Estes Photon Probe Build, Background
The original Estes Photon Probe was only around for two years, from 1991-1993. I have two kits, one original from the 1990s and the second from 2009 when Estes started their "Classic Series. The older kit was #2043, the reissue kit is #3026. Both kits will be built at the same time, I'll be making comparisons between the two. There are some differences. I always thought this was a sister kit to the Photon Disruptor that came out in 1976. Maybe it's the black and white decor with the that orange (or pink or purple) center section. Both designs are BT-55 based and about the same ...

Model Rocket Building: MPC X2 Invader Build, Background
Why another MPC branded model? I needed some ST-7 tubing and are the only vendor left that carries it. The MPC kits are on clearance at $5.00. The box still proclaims: "Flys up to 260 feet!" Every different model design in the MPC lineup says the same thing. My MPC Red Giant (another Sky rocket re-brand) did get to 427' with an Estes C6-5. Besides that, Warner Brothers characters are a favorite of mine, even thought this model looks nothing like the Duck Dodgers cartoon rocket seen at the right. Sometimes it's a nice change to put together an easy one. I find these kits ...
