Supplied as standard with the superb GY611 gyro, the BLS251 is a dedicated ultra high performance tail rotor servo, which is also compatible with the GY601 gyro.
• Futaba brushless servos offer greatly improved response time over other servos. • Significantly increased life span. Futaba brushless servo motors will last more than five times longer than servos that include brushed motors! • Lower operating temperatures. As there aren’t any brushes on the motor armature, no sparks are produced when the servo motor is in operation. • Thanks to the motor design, the outer coils act as a heatsink dissipating any heat that does occur. As an added benefit, Futaba is able to increase the torque and speed of these servos without increasing case dimensions. • Vibration & Shock. Unlike servos that used brushed motors, the brushless servos from Futaba are less susceptible to the effects of vibration and/or shock. • Additionally, the inertia of standard motors also facilitates the effects of vibration on the servo’s performance. By eliminating this inertia in a brushless servo, Futaba has reduced this possibility. • Power consumption. Brushless servos consume approximately the same amount of power as their digital counterparts. • Centering. Centering is the same as it is with the digital servos. The dead band is also equal to the digitals.
Miscellaneous • Increased resolution for smoother operation. • New gear treatment and materials for added endurance and longevity. • Samarium Cobalt magnets for better performance and increased holding power. • Dual ball bearings.
N.B. This servo must be used with a high frequency gyro.
