Safety Notes

2 Power Supply
Power Supply is critical part of the model. For this reason it is highly recommended to use suitable BEC or
battery that can handle used servos. Once wiring and setup is completed it is highly advised to perform the
BEC test. If the test will not pass it is clear the power supply is inadequate and failure will occur.
BEC, Battery or Backup power supply should be connected always at THR, E1 and AUX ports.
THR - used for Throttle output and primary ESC/BEC cable for electric helicopters. For a combustion
helicopters THR port is used for Throttle Servo.
E1 - used for Secondary BEC cable for electric helicopters (recommended for class 500+). For a
combustion helicopters E1 port is used for a Battery lead.
AUX - used for Optional Power Guard system or an additional battery lead. Can output also channel data
for controlling a landing gear, lights, etc.
Do not connect any wire to E2 pin. This pin is shared between Spirit and internal receiver. It is
used for future purposes. Improper utilization of the E2 pin can result in loss of control!
