Ziggy's "Black Knight" rocket hybrid

Ziggy said this about his car:

After building and running a number of IC cars at speed I have deceided to deviate slightly and try to build a non wheel driven car. I was lucky enough to be contacted by Ben Jarvis, one of the few guys in the UK that understands hybrid rocket technology and has the capacity and know how to put together a power system for the car. With his know how of hybrid rocket systems and my understanding of RC technology with regards to speed cars our team has a good chance of building a vehicle capable of 200mph. This car will be called "Black Knight"
