Latest Update: 29th March 2026 - Day 244 - Tajfun 2 and Nova flights

Tajfun 2 - Build Log

Introduction

The Tajfun 2 rocket was developed to get our L2 certification. Again like L1ght Shadow, it was designed to be both a water rocket as well as have the ability to fly on 54mm solid motors.

Rather than the daily updates, here is a video series that covers the development and flights of the rocket.

Part 1 - 21st April 2023

This week we take our Level 2 HPR cert rocket called "Tajfun 2" (pronounced Typhoon 2) on a test flight as a water rocket to make sure it flies well and to test the new deployment mechanism. Later this year we will attempt to fly this rocket on a J360 motor to attempt our Level 2 Tripoli certification.

Part 2 - 28th April 2023

This week we take a look at the start of construction of our Level 2 HPR cert rocket called "Tajfun 2" (pronounced Typhoon 2). We look at making the payload bay tube, the nosecone, motor tube and the removable nozzle.

Part 3 - 6th May 2023

This week we build the pressure chamber for our Level 2 HPR rocket and find out how the rocket got its name Tajfun as well as how Air Command rockets got its name.

Part 4 - 23rd May 2023

This week we add a number of important components to the pressure chamber for securing the shock cord and the payload bay. We attach the nozzle and also make a set of fins.

Part 5 - 17th November 2023

In this episode we look at the details of the Tajfun 2 parachute deployment mechanism and do a few ground tests. Here is the full length video of the first launch as a water rocket: https://youtu.be/aCafRBu3yGE

Part 6 - 24th November 2023

This week we finish the rocket by attaching the fins, rail buttons, and we also paint it. Lastly we also do a full pressure test to make sure the rocket will be able to handle the pressures. Here is the full length video of the first launch as a water rocket: https://youtu.be/aCafRBu3yGE

Part 7 - 1st December 2023

This week we make a few small modifications to get the rocket to fly as a pyro rocket. We upgrade the parachute deployment mechanism. We add a motor retainer and test fly the electronics on a small water rocket.

Part 8 - 8th December 2023

This week we look at the last episode of the Tajfun 2 series where we attempt our Level 2 Certification flight. If you want to see the rest of the series with details of how the rocket was built check out our playlist: https://www.youtube.com/playlist?list=PL-zcDPSotX7omGVVAKBYlbKeJLMf4P_aN
