COMMENTS

The BLS154 is designed for high torque/high speed applications.
Very high current drain is normal at startup. Always use a 4.8V
NiCd battery for best performance.

For full performance of digital servos use them only with FM, PCM and
FASST systems. Do not use digital servos with AM systems.
