Rocket airframes

We currently have more than half a dozen rockets that we use although there are more being built - see Rockets in build for details of these.

Double Trouble

Double trouble rocketA peculiar rocket, this one. Two RATT I-80 hybrid motors in a foam board tetrahedron, with two parachutes for recovery. Challenging to design, build and fly. Not one for Rocksim, either.

Length: 36 inches

Width at base: 24 inches

Materials: foam board airframe

Status: ready to fly

Performance: no idea, but less than 1000 feet

Motors: 2 RATT I-80 hybrids

LOC Warlock

This rocket was built in the summer of 2007, to allow a rapid build of a Level 2 rocket with the very limited ceiling we have at local sites. However, as we wanted to fly it on our Pentamax J and Sky Ripper J hybrids it has a 54mm mount in place of the stock 38mm one and has been stretched by almost 24 inches, so it is much less dumpy.

Length: 72 inches (1.8m)
Diameter: 7.6 inches (195mm)
Materials: cardboard airframe tube, ply fins
Status: ready to fly
Performance: 2500 feet on J1250 hybrid

This is a clone of the BSD Thor, and was used for Ray's Level 2 certifying flight. Odin is capable of flying on 54mm motors such as the Pentamax J hybrid and Pro54 solids, and 38mm motors (Pro38 and Congreve solids). It has flown on the Pentamax J and K motors, and also on our Hypertek J-330. It has been repaired a couple of times after some interesting deployments, including a spectacular zipper, but remains a solid workhorse for some great flights.

Length: 85 inches
Diameter: 4 inches
Materials: cardboard airframe tubes, plastic nose, plywood fins
Status: completed and flown
Performance: 3000+ feet on J motor

Wot 4?

A similar rocket to the Loc IV, but with different fins, this rocket was built in the summer of 2008. An unfortunate first flight left it badly damaged but it is now repaired and ready to go again. New for the rebuild is an Intellicone - a plastic nose with a tube to house the altimeter - which means a separate payload section isn't required, and the rocket is quite short but still capable of taking 36-inch hybrids. Solid construction with through-wall fins and 3 centering rings make the aft end very sturdy, but it's still reasonably light, and capable of flying on the Ratt I-80 for instance.

Length: 64 inches
Diameter: 4 inches
Materials: cardboard airframe tubes, plastic nose, plywood fins
Status: ready to fly
Performance: 4500 feet on J motor


Ray Wilkinson's Level 1 qualifier rocket. It flew at EARS in March 2006, but landed heavily due to a problem with deployment of the chute. After another disastrous attempt on 30 April at Spring Thing, it finally made 4 successful flights at Milson in May 2006 and numerous flights since. It has also been extended to take a RATT I-80 hybrid motor, and to allow dual-deploy for possible Level 2 flights. It has now been retired and will be used for display purposes.

Length: 74 inches
Diameter: 3 inches
Materials: Quantum body tubes, plastic nose, G10 glassfibre fins
Status: retired
Performance: 750 feet on G motor, 3000+ feet on an I

Richter Recker

A very long, lightweight rocket, which flies beautifully on a 3-motor cluster (D or E motors). This rocket uses 2 parachutes for recovery. Now being repaired after a hard landing following recovery failure.

Length: 92.5 inches
Diameter: 2.2 inches
Materials: cardboard body tubes, balsa nose, balsa fins
Status: in repair
Performance: 1500 feet on 3xE motors.

The Slab 

A tetrahedron, made from foam board. The light weight and high drag of this rocket make it ideal for demonstration flights on a G or H motor. It cost less than £5 to build, and is a cinch to fly as it needs no parachute - it just flips over and descends quite slowly. The low altitude means that all the smoke and noise happen close by, and it's virtually oblivious to even strong breezes.

Length: 12 inches (300mm)
Diameter: 14 inches (360mm)
Materials: 5mm foam board
Status: flown
Performance: less than 400 feet on G or H

Little Ripper

A scratch-built rocket specifically for the Sky Ripper G63 hybrid motor, although it would also accommodate our Sky Ripper H hybrid. It's small and skinny.

Length: 52 inches (1.32m)
Diameter: 1.65 inches (42mm)
Materials: phenolic tubing
Status: ready to fly
Performance: 2300 feet on Sky Ripper G63 hybrid, 4400 feet on H78 hybrid

Code Red

This was our first and smallest rocket, bought ready-built just to gain experience. It has made around 20 flights, not all of which have been successful. Despite this, it remains undamaged. The only modification has been to put in a recovery upgrade with a Kevlar shock cord and a nylon streamer or parachute, depending on conditions. It will fly on an A (just), B or C motor. Lost in the autumn of 2007, last seen hanging from a power line.


This has been the workhorse of our initial rocketry activities. Built from a kit, it has since been extended after we lost the nose, and has also been modified into a 2-stage rocket. This extends the maximum altitude to an estimated 2500 feet, although we plan to measure it once we have an altimeter fitted. 2-stage flights are on a D booster over an E main stage. Many of our students have flown this rocket, and it has made more flights than any of our others. Sadly, the Estes E motors, which fly it beautifully, are no longer available.

Length: 48 inches (1.22m)
Diameter: 1.35 inches (34mm)
Motors: single-stage D or E (Black Powder), dual-stage D boost, E sustain
Rated Performance: D: 600 feet, E: 1400 feet, D+E: over 2500 feet estimated
