Futaba BLS252: Precision Drive for F3C Helicopters

The Futaba BLS252 Brushless Helicopter Servo is a top option for F3C competitors who want reliable, repeatable control. This standard-size unit uses metal gears and dual ball bearings to keep movement smooth, and it achieves about 30% faster response than typical digital servos while using similar power to brushed types. Its brushless design also delivers roughly five times the operating life of brushed motor servos, making it a sensible upgrade for serious pilots.

Top Features and Included Parts

  • Enhanced Performance: Built for F3C use, tuned for faster response and steady control under demanding routines.
  • Durable Construction: Metal gear train and two ball bearings provide strength and smooth operation.
  • Comprehensive Kit: Supplied with a selection of servo horns and mounting hardware for flexible installation.

Specifications

  • Torque: 139 oz-in (10.0 kg/cm) @ 4.8V; 175 oz-in (12.6 kg/cm) @ 6.0V
  • Speed: 0.16 sec/60° @ 4.8V; 0.13 sec/60° @ 6.0V
  • Dimensions: 1.6 x 0.8 x 1.5 inches (40 x 20 x 37mm)
  • Weight: 2.1 oz (58g)
  • Horn Screw Size: 3x8mm

Futaba BLS252 brings consistency and extended life to F3C setups, ideal for pilots who fly high precision routines and need dependable servo performance.

The BLS252's brushless motor and efficient gear train cut actuation delay, giving faster servo response that benefits tight F3C maneuvers.
No special mounts are required for most standard F3C frames; the included horns and hardware cover common installation options, but check your frame hole spacing first.
Yes. The BLS252 interfaces like a standard digital servo, so it works with typical gyros and ESCs; confirm voltage compatibility if you run higher supply voltages.
