ProTek RC 500BL Black Label High Torque Brushless Mini Servo The ProTek 500BL Mini is the next step in mini servo performance. Developed for 1/12 and 1/10 pan car, as well as 1/10 Pro Class drag racing pan car style chassis that use a mini size servo, this brushless option produces 186oz of torque and .06 transit speed at 7.4 volts - with superior efficiency and lifespan. A black anodized aluminum case with a blue anodized bottom cover provides a stealthy and clean look. The aluminum case allows for extreme durability and a precision fit for the servo gears to provide the precise control necessary for demanding enthusiasts. Metal gears and brushless circuitry round out the package to create a robust option that will go the distance in high demand applications. NOTE: If you experience glitching or poor performance while using a Futaba transmitter, you must turn off BLS mode. BLS mode is only compatible with Futaba BLS type servos. Modification may be required for drag applications.
