This Christmas the kids invested in three Viper Bot kits from FingerTech. They are the coolest, most robust little robots. They were easy to put together and easy to modify and weaponize and tinker with. They drive really well and even Essy is getting pretty good at controlling them. We have a very kind e-friend, who was on the Discovery BattleBot series, on Team Lucky, and he recommended this kits for my kids. After several months and many attempts to gather all the parts from various suppliers overseas to get the electrical together to build a bot from scratch, finding these kits was definitely the best option. We're still working on a from scratch kit that the Vipers can use as a battle dummy. Thanks, Andrew! We can't wait for the 2019 Battlebot season!!!
