BK servos are a product developed by Bert Kammerer, the project was started in early 2013 while Bert was working on the development of the “Goblin 500” helicopter from SAB Heli Division, an Italian RC helicopter manufacturer. The Goblin 500 used mini (mid size) servos and unfortunately every single one of these servos available on the market at the time were just not what Bert wanted for testing, they either lacked speed, torque or they centered poorly. After some research, Bert realized that there was just no way to have a fast, strong and accurate servo with such a small motor, therefore the solution was to use a full size servo motor and fit it in a mid size servo case! The 5000 series BK Servo employs a full size motor in a mini case, this allows for blazing speeds combined with good centering and plenty of torque.
Thanks to the success and popularity of the mini servo, a few months later Bert decided to design a new full size servo, the coreless full size servo not only features a clever design, but it is also lightning fast and very precise. The best part of the coreless full size servo is its price point, just under $100.00, this servo offers an incredible value never seen before in the RC industry. Finally, for those of you who like brushless, also have a brushless line! The brushless servos combine good torque and speed and are suitable for any application from helicopter hard core 3D, to speed or F3C flying. They’re also excellent servos for surface applications, such as 8th scale off road racing.
