Frequently Asked Questions:
Q: Is the BLS815 suitable for use as a tail/rudder servo?
A: It is primarily designed for high-torque cyclic (swashplate) use, but KST offers dedicated, faster tail servos like the BLS805X/905X.
Q: What is the maximum safe operating voltage for this servo?
A: The maximum rated operating voltage for the BLS815 is 8.4V, making it a true High Voltage (HV) servo.
Q: Does this servo require a special servo programmer to set the soft start feature?
A: Yes, programming features like soft start and travel limits usually require a dedicated KST servo programmer tool.
