WARNING: Do not install the propeller until the aircraft has been
completely assembled, all the systems have been checked thoroughly
and you are located at a suitable fl ying site.
Follow the instructions below to install the propeller and spinner.
1. Install the propeller (E), backplate (B),washer (D), and hex nut (C) onto the
motor shaft.
2. Thighten the hex nut with a 10mm wrench to secure the propeller into place.
3. Push the spinner (A) onto the backplate until it clicks.
IMPORTANT: The motor shaft and prop nut are reverse-threaded. Turn the prop nut
counter-clockwise to tighten it to the motor shaft.

SMART Technology Electronic Speed Control (ESC)
The Apprentice STS is equipped with an exclusive Smart ESC that can provide a
variety of real-time power system related telemetry data including motor RPM,
current, battery voltage and more to compatible Spektrum AirWare™ equipped
transmitters (including the DX6e and 8e, DX6 and 8 G2, the DX9, iX12 and others)
while you fl y.
Access the telemetry data by plugging the ESC into channel 6 on the A3230 Flight
Controller. The ESC will send the below information to the fl ight control and the
information will be displayed on the compatible transmitter.

Low Voltage Cutoff (LVC)
LVC is a function built into your ESC to protect the battery from over-discharge.
When the battery charge is low, LVC limits power supplied to the motor. The aircraft
will begin to slow and you will hear the motor pulse. When the motor power
decreases, land the aircraft immediately and recharge the fl ight battery.
NOTICE: Repeated fl ying to LVC will damage the battery.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle
discharge. Charge your Li-Po battery to about half capacity before storage. During
storage, make sure the battery charge does not fall below 3V per cell.
