During the pandemic in 2020-21 it became clear that in order to get a new design fin bracket machined I was getting too dependent on external factors. Hence the decision was made to become self-sufficient with the conversion of a manual HBM BF 25 / G0704 mill/drill into a full blown DIY CNC milling machine.

After a great boost, the BOOSTAR-TWO / GIGA IV two stage rocket flew to a disappointing 8+km as the 2nd stage motor experienced a catastrophic anomaly upon delayed ignition at the LRE summer 2021. Please click here for the full launch report.
To determine the cause of failure of the GIGA IV flight one of the items we never knew for sure was tested. A casing was machined from the same batch of aluminium tube as flown in the GIGA IV flight. Two forward closures were installed and the casing was filled with water. A hydraulic hand
The BoostarTwo / GIGA IV rocket finally flew after 1 year in storage but suffered a CATO of the sustainer motor. Stay tuned to see the full report of this flight.

On Friday 28-05-2021, LD and myself set out to launch the Intimidator 5 on what I think is it’s 8th flight but frankly lost count a bit and not all flights were properly documented on this site. Weather was mostly sunny, little to no wind from the N-NE direction. Launch rail was set at 32°
On 24.09.2020 we tested to see whether the BOOSTAR-TWO and the GIGA IV would fit together in the launch rail and to prevent unpleasant integration surprises at the LRE. Espcially orientation of equipment and launch buttons are critical. All went well and within the hour the BOOSTAR-TWO / GIGA IV were erected and lowered from
*** This is not my motor *** Static test of LD’s – 130mm monolithic 12 point star BOOSTAR-TWO. Intended as a booster for the BOOSTAR-TWO / GIGA IV rocket. 65/10/0.5 RIO propellant Motor diameter 130mm, 1880mm length. 19.1kg propellant, overall weight 34.8kg. 30g silicone APCP / 15g thermite igniter.

Stainless steel head end igniter body from the GIGA III flight was re-furbished. For high altitude ignition the fuse head igniter was dipped in a slurry of BKNO3 viton aceton and left to dry. 3gr RIO/CuO/Mg thermite charge in heat shrink tubing as initial igniter. Booster ignition charge on top of monolithic grain consiting of
