Carbon Cub S2

The Carbon Cub S2 is upgradable with the addition of the optional LAS
module (SPMA3180 not included) this allows the advanced SAFE features
to be combined with an Landing Assist Sensor (LAS) for smoother gentler
landings.
IMPORTANT: For best results when using LAS, land on grass surfaces or a
light colored surface, such as light colored concrete. Black surfaces or water
normally do not have enough reection for the sensor to receive accurate
readings.
Installation of the LAS module
1. Remove the wing to gain access to the ight controller compartment.
2. Rotate the aircraft to access the bottom of the fuselage.
3. Press the factory installed plug (A) to release it. Then removed it from
the LAS pocket. Save the plug for ights without LAS module.
4. Feed the LAS connector through the channel in the base of the LAS
pocket.
5. Align the LAS module with the wires facing the back of the aircraft. Place
the LAS module into the pocket and press it to secure it into place with
a click.
6. Place the aircraft on its landing gear and connect LAS connector to
Channel 7 on the ight controller. For correct polarity of the plug ensure
that the orange (not brown) signal wire (B) is facing towards the front of
the aircraft when plugged into the ight controller.
Landing with LAS
Reduce throttle, keep the wings level and slowly reduce the altitude of the
aircraft. When the aircraft’s landing approach reaches an altitude of roughly
1m the LAS will level off the aircraft, manage the throttle and then are the
aircraft for touchdown.
IMPORTANT: LAS is functional for all SAFE ight modes except for
Experienced Mode. When the ight mode is switched to Experienced mode
the LAS is deactivated and the pilot will have zero assistance on landing, a
traditional manual landing of the aircraft is necessary.
IMPORTANT: Installation of the LAS module is not auto land. The aircraft
must be guided and aligned with the landing strip for landing.
LED Indicator
When the LAS module is installed the aircraft’s LED indicator for beginner
and intermediate ight modes will be followed with a purple ash to indicate
that the LAS System is active.
LAS with GPS
With GPS installed LAS will assist the Auto Land mode during landing of the
aircraft. When the aircraft’s landing approach reaches an altitude of roughly
1m the LAS will level off the aircraft, manage the throttle and then are the
aircraft for touchdown.
TIP: If the speed of aircraft is too fast for landing or above 20% throttle
setting, LAS is not effective.
TIP: LAS is not active in Experienced mode.
