Launch of a two stage Super Big Bertha model rocket
On November 3 2013 I launched a Super Big Bertha model rocket coupled to a second stage booster that I scratch built. The booster sported 3 Estes D12-3 motors and the rocket was air-started with a D12-5 in its motor mount. A payload bay carried a cheap micro camera that I bought on eBay. The upper stage was electronically ignited by a digital timer set to ignite the rocket at 1 second after liftoff.
