Test fired 3c of 4 exploded

As part of the series of ongoing ground testing of the homemade reusable solid rocket motor. In this video, the engine was loaded with a 1.3kg propellant a little below its maximum capacity of 1.6kg. The engine however failed to complete because the forward closure blew off from the combustion chamber. One contributing factor to the incident was the reduction of the grain hole diameter. from 8mm to 5mm. What this does is increase propellant burn time, which has a direct effect on wall pressure. The situation is noted and is getting resolved.
