How does the brushless design affect longevity?

Brushless motors run cooler and with less wear on brushes, which generally results in a significantly longer service life compared with brushed servos.

Are there upgrade paths for more torque?

If you need higher torque, consider larger servos in the same class or gear upgrades, but check airframe weight and balance before changing hardware.

Will it fit my existing control horns?

The Futaba BLS155 uses standard horn splines and should accept common horn sizes, though you should confirm spline compatibility with your current setup.
