The Blue Bird Servo BMS-210DMH is the top choice for park flyer and 450-class RC helicopter pilots who do not want to compromise on high performance despite a budget-friendly price. Controlled by modern digital electronics, the coreless motor delivers power to a high-quality, double ball-bearing metal gear without delay. A metal heat sink ensures that the 12 mm servo effectively dissipates heat even under heavy load. With nearly 4 kg of torque at 0.13 seconds, it provides ample reserve, even in more demanding situations.
