Malcolm;
I noted in their Technical section that they recognize the potential
problems with torque reaction & gyroscopic precession on their jet
engine; also the disadvantages to frontal area & drag of the jet air
intake and the rider's position relative to the engine.
These problems can all be overcome by a rocket motor. It's very small so
the frontal area can be minimized, it requires no air intake duct and no
rotating mass means the torque & precession problems are eliminated. A
rider can be positioned in front of the motor and fuel/oxidizer tanks.
I have an Aerojet- General rocket motor from the upper stage of a Nike-
Ajax. It has a diameter of only about 7" but has a static thrust of
2,000 lbs and it weighs a small fraction of a J-58. If I remember
correctly it consumes RFNA (red fuming nitric acid) and aniline about
10lbs per second. Anyone for putting the world's fasted moped in the
record books?

Even if thrust power is not your choice of power unit check out a new UK
programme going for the outright record on two wheels -

Who wants to lie across a J-58 - or indeed any jet?
