One Small Step .........

This is the business end of a Diplo 220x55 mm solid fuel rocket motor. It consists of two home-made extruded 110x55mm solid fuel cells stuffed end to end into the pipe. The nozzle is cast ceramic. This lot (and possibly multiples of) are contained in a blast box to minimise the risk from errant motor combustion. Not immediately obvious from this picture, but the blast box is bolted to the back of one of Diplo Jnr's push-bikes - we've some work to do because this is an ex skip-find bike that has been stripped of brakes etc for stunt use. Ignition is via a home made Diplo electronic initiator powered by a 12 volt battery using a "GO" button on the handle bars. As with all solid fuel boosters, there is no "OFF" switch. Earlier static motor tests indicate we could be in for some massive thrust and impressive speeds. We have had some huge motor explosions as well but we are confident that recent technical improvements have eliminated the most dangerous problems. MORE ROCKETRY !

Make sure you are sporting the skid lid when you fire her up Diplo!
