Blue Bird BMS-A12H Servo - 4.6Kg.cm 0.09s 8.4g 8mm

The Blue Bird BMS-A12H is a great new wide voltage range (WV) servo with amazing torque, speed and precision in a tiny case only 8 mm thick. The H suffix relates to the horizontal (conventional) servo mounting lugs fitted, making this servo ideal for fuselage mounting. It is a fully compatible upgrade to the BMS-A10H we were peviously stocking.

With a weight of 8.4g and a speed of 0.09 sec/60° the Blue Bird BMS-A12H is ideal for DLGs, F3K, F3P, F5J, and all electric racers, small gliders and 3D RC models. Being so thin and lightweight the A12 is also ideal for installation in the tail surfaces of larger models.

With a wide voltage range from 3.7V to 8.4V the BlueBird A12-H works perfectly on 1S and 2S LiPo, and well as 4 and 5 cell NiMH batteries.
