Smart Technology Electronic Speed Control (ESC)
The Apprentice S 2 1.2m is equipped with an exclusive Smart technology
electronic speed control that can provide a variety of real-time power system
related telemetry data while you fly, including motor RPM, current, battery
voltage and more to compatible Spektrum AirWare
™
equipped transmitters.
When powered on, the ESC will send the below information to the flight control
and the information will be displayed on the transmitter telemetry screen.
• RPM*
• Voltage
• Current • Throttle
• FET Temperature
• BEC Temperature
* For the RPM telemetry information to display correctly, you must program the
motor pole count into the Telemetry settings of your transmitter.
The Apprentice S 2 1.2m uses a 14-pole motor.
To program the motor pole count information:
1. Power on your transmitter.
2. Set the throttle cut to on.
3. Power on the aircraft and allow it to initialize.
4. In your transmitter, go to the
Function List
( Model Setup in iX series transmitters).
5. Select the Telemetry menu option.
6. Go to the
ESC
menu option.
7. Scroll down to Poles .
8. Enter 14 (for iX series transmitters, you must click save to save your changes).
9. Return to the main screen.

IMPORTANT: We recommend flying with floats only when you are able to fly
comfortably in Experienced flight mode.
Only use the floats if you are comfortable flying your aircraft and have repeatedly
taken off, flown and landed with success. Flying off water poses a higher risk to
the airplane because the electronics can fail if fully immersed in water.
Optional floats and float mounting wires (HBZ7390) sold separately.
Always ensure the optional floats are secure on the fuselage before putting the
aircraft in water.
To take off from water:
1. Slowly increase the throttle, steering with the rudder to keep the aircraft
tracking straight and into the wind. Avoid rapidly increasing the throttle
as torque from the motor may cause the aircraft to roll to the left when on
water.
2. Hold a small amount (1/4–1/3) of up elevator and the aircraft will lift off
once flying speed is reached.
3. Keep the wings level on takeoff.
To land this aircraft on water, fly the aircraft to a couple of feet off the surface
of the water. Reduce throttle and add up elevator to flare the aircraft.
When taxiing, you must use throttle to move the aircraft forward, but steer with
the rudder stick. The stick will turn both the aircraft rudder and a small rudder
attached to the left float.
Avoid taxiing cross wind if there is a breeze, as this can cause the aircraft to
flip over if wind gets under the upwind wing. Taxi 45 degrees into the direction
of the wind (not perpendicular to the wind) and use aileron to hold the upwind
wing down. The aircraft will naturally try to face into the wind when taxiing.
Always fully dry the aircraft after landing on water.
CAUTION:
Never go alone to get a downed model in the water.
CAUTION:
If at any time water splashes in the fuselage while flying
from water, bring the airplane to shore, open the battery hatch and
immediately remove any water that may have gotten in the fuselage. Leave
the battery hatch open overnight to let the inside dry out and to prevent
moisture damage to the electronic components. Failure to do so could cause
the electronic components to fail, which could result in a crash.
