Note: When using a separate Ni-Cd receiver battery as a power source, the operating
voltage range is 4.8–6.0V (4–5 cells) underload.
Attention: Make sure the male and female connectors have the correct polarity (+/–)
before connecting. Be sure to orient the servo plug correctly for proper insertion.
Most electronic speed controllers are set up for Battery Eliminator Circuit (B.E.C.) operation
and plug directly into your receiver. See Figure A for a typical setup and check your speed
controller’s manual for correct installation.
