Vertical flywheels were a type of rotating weapon. They were typically quite large and thin and were capable of damage on a large scale. Whilst typically unsuccessful in the UK, robots with this weapon became the German and Dutch Champions, and Cyclone won an annihilator in Robot Wars: Extreme Warriors.
This weapon was typically more successful in BattleBots, with the widely famous Nightmare, who inspired a number of UK Robots. House robot Matilda initially had a chainsaw but changed to a 27 kg flywheel after Series 4, although the flywheel was said to be interchangeable with the chainsaw in Robot Wars: Extreme Warriors.
- A flywheel was a comparatively heavy disc weapon that spun at high speeds. To cause damage, welded "teeth" were attached at places on the weapon to gouge enemy robots.
- They were mounted vertically, with the purpose of striking from the bottom up.
Advantages and Disadvantages
- Vertical weapons were capable of doubling as flipping weapons, even capable of throwing an opponent out of the arena, as X-Terminator, Cyclone and Matilda showed.
- They often targeted the underside of a robot, the weakest point on the design. This allowed for maximum damage.
- They proved effective against flippers; buckling the wedge of flipper meant that it was neutralised - unable to negotiate ground clearance. X-Terminator showed this in its Semi Final fights against St. Agro and Bulldog Breed.
- The design was often hard to combine with the invertible design, especially large flywheels such as the likes of 259. This meant that often, a robot with this weapon needed an additional srimech.
- Also, the effectiveness of the weapon when inverted was often decreased due to many flywheels spinning in only one direction. This was shown when Black Hole was overturned by Philipper 2 and its discs span towards the ground, causing Black Hole to jump upwards upon striking its opponent.
- In a clash between horizontal and vertical heavy rotating weapons, a vertical will typically come off second best, as shown in the clash between Fluffy and 259.
- They have a narrower range of attack than Horizontal flywheels.
