. . . "Vertical flywheels are a type of heavy rotating weapon which first became prominent in later series of Robot Wars. The first robot to be equipped with such a weapon was Daisy Chopper in Series 3, while the most successful UK series competitors to be equipped with one include the Series 7 version of X-Terminator, which finished fourth in that series, Series 5-6 Semi-Finalist S3 and joint Battle of the Stars champion Kadeena Machina. House Robot Matilda was also equipped with a rear-mounted vertical flywheel from Series 5/Extreme 1 onwards, replacing her chainsaw in the UK series and being made interchangeable with it in Robot Wars: Extreme Warriors and Nickelodeon Robot Wars. Whilst vertical flywheels have not been as common or as famous as their horizontal counterparts in the UK series, robots with this weapon type also enjoyed considerable success in international versions of Robot Wars. Dutch Series 2 Champion PulverizeR and German Series champion Black Hole were both equipped with these flywheels, as was US competitor Cyclone, which won the Annihilator in the second season of Extreme Warriors. They also enjoyed some success in the lower weight categories, with Argh! winning the Extreme 2 Featherweight Championship by using a vertical flywheel to devastating effect."@en . . . .
