Overall Rating:

Contributed by Edward Chess


Celtic Thunder is a ring fin rocket that has a unique Celtic Knot fin ring design (an interlocking of three BT-80 rings). The finished rocket is 12.25" in length, has a balsa nosecone, is based on a BT-50 body tube (0.976" diameter), and has a fin span of 4.0'.  It flies on 18-mm engines (the recommended engines are A8-3, B6-4, and C6-5), and equipped with a 48" crepe streamer.  The original design was by Ray DiPaola from CMASS (NAR Section #464) and CATO (NAR Section #581).  FlisKits offered the Celtic Thunder as the Fliskits' 10th Anniversary Commemorative kit in 2012.


There are only 17 individual parts in this kit, but it is more than your typical 3FNC.  A complete list of parts is as follows:

  • Hardware Pack:
    • 1 Engine block, 18mm
    • 2 Centering rings, BT20/BT50
    • 1 Kevlar shock line, 18"
    • 1 Shroud line, 12"
    • 1 Screw eye
    • 1 C-size engine hook
    • 1 Launch lug, 1" x 1/8"
    • 1 Streamer, crepe, 48"
    • 1 Tape disk
  • Loose parts:
    • 1 Nose cone, Balsa
    • 3 Body tubes, 1" long (BT-80)
    • 1 Body tube, 9" long (BT-50)
    • 1 Elastic shock cord, 18"
    • 1 Decal sheet
    • 1 Tube marking guide
    • 1 Instruction sheet

The components were all of high quality.  The BT-80 ring fins were not cardboard, but a spiral-wound material like mylar that is very stiff and stable. I'd love to buy body tubes from this material.

Favorite Rockets: My all-time favorite model was the Estes Orbital Explorer, which I never did get to fly correctly. Still loved it, though!


I was introduced to model rocketry in 1976 by several school friends who belonged to an ad-hoc rocketry club.  I've been building kits and launching on and off ever since, most recently a few weeks ago with my son, who is now the same age I was when I began the hobby. I was a young boy during the height of the NASA Apollo program and have always had a rich interest in rocket flight and space travel.

Model Rocket Building: Odd'l Rockets Goony G-16 Build, Part 1, Parts
The new Odd'l Rockets F-16 kit is almost ready! The fins have been laser cut and almost all the parts are here. After the instructions are drawn up you should build a model using them to be sure everything works and check the fit of the water slide decals on the laser cut fins. To be honest, I've made too many prototypes and wasn't excited about building another normal F-16. I decided to make a BT-60 Goony version using spare parts with the same fins and decals used in the Odd'l Rockets F-16 kit. The parts picture is different, this wasn't going to be a blog build. But the model turned ...

Model Rocket Building: PML Lunar Express Build, Part 1, Parts
From what little I know about mid-power the parts seem to be very good quality. The gray tubing (I should call it an airframe, this is mid power and all) is Quantum Tubing. A polymer tube, it looks like gray plastic. The fins are G-10 fiberglass are .062" or about 1/16" thick. To the far right are the molded urethane landing pads. The launch lugs are 1/4" diameter brass. The 38mm motor mount (brown tube) is thick phenolic. On the low right is the ejection piston package. To check out the instructions, CLICK HERE The nose cone and tail cone are plastic. The nose cone has a well formed resin ...

Rocketeer's Corner: What a jerk!
The Falcon Rocketeers get ready to weigh their rocket before a flight (Click to enlarge). We are now in "crunch time" - those last couple of weeks before the TARC deadline, ones in which the teams make every effort to get some practice in before setting up their qualification flights. Pegasus field hosted the Falcon Rocketeers and Hope Rising on Thursday, which tuned out to be a good day for both teams. Falcon had no catos and achieved a couple of decent flights, so they decided to make a qualification attempt. Unfortunately the rocket traveled a bit too high, ...

Blast FromThe Past: MPC Lunar Patrol Clone Part 1
Way back in 1974, during the fledgling days of my model rocket career, I placed an order with Model Products Corporation for some rocket kits and engines. The order included the Flatcat, a Flare Patriot, a Theta-Cajun, and a Lunar Patrol. The latter intrigued me because of the pair of delta-wing gliders that served double purpose as the model's fins. I built the model and took it to one of the club meets to launch it. When the launch button was pressed, I didn't get the expected soaring flight. Instead, the model blew up on the pad! A seriously defective MPC 'A' engine ripped the booster ...

Rocket N00b: NARCON 2017 Review
A Black Brant V sounding rocket, from Wallops Flight Facility, parked all weekend outside NARCON I'm finally back from NARCON, and what a weekend it was! Three days of presentations on all aspects of rocketry, plus museum tours, dinner, and a speech by one of model rocketry's beloved company founders, all took place at the Crown Plaza Dulles Airport hotel in Herndon, Virginia, just outside Washington, D.C. The hotel was conveniently located a short shuttle ride from the airport, and not far from the National Air and Space Museum's Udvar-Hazy Center. Plus, there was a real NASA sounding ...
