FingerTech Viper Combat Robot Kit (v3)

FingerTech Robotics’ Viper is the standard beginner platform of the 1 lb (454 g) antweight class used in SPARC and NHRL events. In its v3 form the base robot weighs 313 g and measures 14 × 16.5 × 3 cm, leaving room under the limit for a builder’s own weapon. The kit supplies an aluminium baseplate, two Silver Spark 33.3:1 gearmotors, two tinyESC speed controllers, foam wheels, a UHMW front and a PETG lid.

Out of the box the Viper is a weaponless pusher; FingerTech sells lifter, vertical spinner and tail spinner modules, and with extra parts the design scales to the 3 lb beetleweight class.

The base price is CAD 229.73 without radio and battery; a transmitter and receiver add CAD 81.08, a 9 V battery CAD 27.93 and a LiPo pack CAD 94.37. The product is on sale; the maker’s page showed 30 units in stock alongside a pre-order note for the next batch.
