In Service


This was our first rocket to user a spliced bottle, and is our most commonly launched rocket, as it is light and quick to pressurize. 


It has also been launched with the 15 mm Nozzle and Launch Tube

Side Deploy (RRT1)


In Service


This was our first rocket to use a 15 mm nozzle and 9 mm, and is our first rocket to use the new generation of spliced bottles, fins and Side Deploy. 


Blue Diamond 2a had only 2 spliced bottles with no bottle onto to cushion impact if chute didn't deploy, crashed on maiden flight due to parachute tangle.

In Service


This was our first large rocket to fail on take off due to the nozzle being to small- in development and will try with bigger nozzle and new Air compressor.


First flight with larger nozzle crashed, due to parachute ripping off. This destroyed the Release System and the Fairings but the bottles survived!

Design and Preparation


This is our most ambitious rocket planned and all the present work is in preparation for this. It will use a 2m launch tube, and a more Powerful compressor to pressurize.

Design and Preparation


Plus we are going to be fiberglassing the bottles to allow them to reach higher pressures, for this new rocket, with a target pressure of around 200 PSI.


I am going to use this project to count towards my EPQ (Extended Project Qualification). It will use the RRT2 and Servo Timer II Flight Computers, along with 2 onboard cameras.
