Hans Litjens returned to Weston Park International Model Show to deafen everyone with his self built 'Scout' pulse jet. It's got wingspan of 1.2 metres and flies like a bullet once released from its launch ramp by means of a stretched bungee cord. No throttle on this model. It flies at maximum power until the fuel runs out or Hans cuts the fuel supply remotely from his transmitter.
