Second static test firing of a hexaphenox rocket motor, using KNO3 instead of KClO3. Moderating the burn rate and avoid a runaway reaction by using a mixture of KNO3 and KClO3 as oxidizer (3.7g KClO3, 3.8g KNO3, 1.5g hexamine and 1g catalyst).
A static test firing of the DoubleSShot rocket motor is scheduled for end of July. The DSS rocket engine is the biggest ever built "sugar propellant" motor. Below videos showing some early static test firings of proto/miniSShot motor types:

A very easy rule: For every 10000 likes our partner Sugar Shot to Space receives on facebook, Markus from Team Selene will donate 1000USD for the eXSShot mission to space:
- Chris King reports the following progress on the DSS avionics test bed: "1. UFC-4 flight controller. Installed into test bed. Established 2-way communication over the RF telemetry link and computer com ports. Hardware reports passing test results. Recharged on-board batteries. Human interface is powerful so it is also a little complicated. 2. Telemetrum flight controller. Installed into the test bed. Established 2-way communication over the RF telemetry link to ground station and computer com ports. Hardware reports passing test results. Easy set up and human interface.

First static test firing with hexaphenox propellant, using an empty C6 motor casing. Combustion chamber pressure was way too high which led to the explosion of the motor:

The hexamine/KClO3/substance X mixture has been named Hexaphenox. The name might give you a hint to win the The 1000 Dollar Chemistry Competition. The slowmo video shows an ignition test of 3g Hexaphenox via electric match:
- An avionics telecon was held this past Sunday to review past progress and to discuss current and future tasks. Participants were Chris King, Mattias Lampe, and Richard Nakka. Mattias recommended the use of two dipole antennas mounted in the nosecone, both etched on PCBs and ring shaped, of approximately 10 cm and 15 cm diameter. These would be for 400 Mhz and 900 Mhz transmissions. Mattias is in the process of producing prototypes for testing. Chris provided an update on procurement status of the various avionics components. Chris currently has in his possession: 1. UFC-4 Flight Computer

An experiment I did today. Hexamine and KClO3 are not shock or friction sensitive like many other fuels with this strong oxidizer. Combustion of hexamine and KClO3 is hesitant, a lot of heat need to be applied to ignite, bigger amounts are even not able to ignite. Adding substance X, the combustion is vigorous and the mixture ignites immediately:

RoverX with mounted LADAR: The laser has a power of 30mW and a wavelength of 980 nm (IR, not visible for human eyes). The robot will no be programmed to run at least 500 m autonomous on rough terrain.
