FAILSAFE AND LOSS OF SIGNAL

FUTABA S.BUS AND SPEKTRUM/JR DSM

When using Futaba receivers with S.Bus or S.Bus2, or using Spektrum 

or JR receiver satellites with DSM2 or DSMX, the Synapse Flight 

Controller can detect signal strength and a loss of signal event. 

Setting failsafes in the receiver is not necessary, as failsafe behavior 

is set in the ALTA App. The radio’s failsafe settings will not be used.

PPM RECEIVERS

When using a receiver with a PPM output signal, the Synapse Flight

Controller will not automatically detect loss of signal and will follow

the radio controller failsafe commands typically set during the bind 

process. Refer to your radio controller manual for information

on setting up failsafes.

 WARNING 

Improperly set failsafe settings on PPM radio receivers can cause 

unexpected flight behaviors if ALTA loses radio control signal. 

After setting radio failsafe settings, ensure they are correct by 

viewing the channel mapping parameters in the radio configuration 

screen in the ALTA App, or viewing radio charts in the ALTA App. 

Ensure that the radio commands behave as expected when the 

radio controller is powered off.

COMPASS CALIBRATION

ALTA features a highly sensitive 3-axis magnetometer that measures the 

earth’s magnetic field to infer heading. Occasionally, the compass will require 

calibration, especially when traveling between different geographic locations.

TO PERFORM A COMPASS CALIBRATION:

1. Secure a battery onto ALTA (see page 18-19)

2. Plug in the battery

3. Open the ALTA App

4. Select Configurations > More > Compass

5. Under Calibration, select Start Manual

6. Follow the on-screen instructions

 WARNING

Verify ALTA is disarmed prior to performing a compass 

calibration. To ensure ALTA does not arm, set the Arm 

Enable Switch (if available) to disable, and remove the 

Configuration Jumper.

 NOTE

It is recommended to use two people to perform the compass 

calibration as it requires handling and rotating ALTA. Perform 

calibration without a payload attached.

 NOTE

Ensure a microSD card is installed in the GPS/compass module 

prior to performing compass calibration.
27 | SETUP GUIDE WWW.FREEFLYSYSTEMS.COM

 CAUTION

Always neutralize control inputs when switching 

between control modes.

CONTROL MODES

ALTA has three primary flight control modes: Manual Mode, Height Mode, 

and Position Mode. They are selected with the Mode Switch.

MANUAL MODE

In Manual Mode, ALTA will only stabilize its attitude. At neutral 

control input (middle pitch and roll stick position), ALTA will 

attempt to remain level. Throttle control is direct.

HEIGHT MODE

Height Mode changes the throttle stick behavior to command climb and 

descent rates. The higher the throttle stick position, the faster ALTA will climb. 

Conversely, the lower the throttle stick position, the faster ALTA will descend. 

When the throttle stick is centered, ALTA will enter Height Hold. In 

Height Hold, ALTA will maintain a target altitude and try to correct 

for drift. If a disturbance moves ALTA away from this target altitude, 

ALTA will climb or descend to return to the target altitude.
28 | SETUP GUIDE WWW.FREEFLYSYSTEMS.COM

CONTROL MODES (CONTINUED)

POSITION MODE

Position Mode changes the pitch/roll stick behavior to command 

ground speeds. Pitch and roll stick deflection will command fore/

aft and left/right ground speeds respectively. Controlling altitude in 

Position Mode is the same as in Height Mode.

With pitch and roll controls centered, ALTA will enter Position Hold. In 

Position Hold, ALTA will maintain its position over a given point on the 

ground and correct for disturbances.

Position Mode requires a strong GPS signal. If a weak signal is 

present, ALTA will not enter Position Mode, and if the GPS signal 

degrades while in Position Mode, ALTA will automatically revert to 

Manual Mode.

AUTOLAND

The Autoland function will command ALTA to hover for 10 seconds 

and will then land in place. It only occurs if Autoland is selected as the 

Loss of Signal (LOS) event in the ALTA App, or at the end of an LOS 

Return-to-Home (RTH) event. If ALTA is above the app-configurable 

Safe Height setting, ALTA will first descend to it at the Maximum 

Descent Rate. After reaching this height, ALTA’s descent will slow to 

the Autoland Descent Rate.

 CAUTION

Flight using Position Mode in areas of degraded GPS signal, such as near buildings 

or under dense tree cover, is not recommended. The reversion to Manual Mode can 

sometimes cause abrupt changes in flight behavior.

RETURN-TO-HOME

Return-To-Home Mode will command ALTA to fly back to the starting 

point of the flight or the last defined Home Point. When ALTA first 

acquires a GPS position, it sets this as the Home Point of the flight. 

The Home Switch on your radio controller can also be used to set a 

new Home Point. See Channel Mapping in the User Manual for more 

information on setting up the Home Switch.

RTH can be initiated manually by the Home Switch or be initiated with 

an LOS event.

When initiated with the Home Switch, ALTA will fly back to the Home 

Point, and the pilot will maintain control of ALTA’s altitude the entire 

time. ALTA will not autoland if adequate signal is detected. The pilot 

can cancel the RTH procedure by commanding a pitch or 

roll command.

During an LOS event, ALTA will first check its current altitude against 

Safe Height. If it is lower, it will climb to Safe Height, and if ALTA is 

above Safe Height, it will remain at its current altitude. Next, ALTA will 

fly back to the home position at the RTH Speed set in the ALTA App. 

Finally, upon reaching the home position, ALTA will begin Autoland.

TUNING ALTA

ALTA comes pre-tuned for a wide variety of payloads and flying conditions. 

Generally, additional tuning is not required to fly ALTA, and additional tuning 

will only need to take place if more customization of control feel is desired. For 

more information on tuning parameters, refer to the ALTA User Manual.

 WARNING

Tuning can change the fundamental flying characteristics of ALTA. 

It is possible for ALTA to become unstable or even uncontrollable 

if values are set too high or too low. Only change tuning parameters 

in small increments and with caution. Always test new tuning 

configurations in open areas away from people or obstacles.
33 | SETUP GUIDE WWW.FREEFLYSYSTEMS.COM

SETTING HOVER THROTTLE

Hover Throttle is an app-configurable parameter that adjusts ALTA’s thrust at 

center throttle stick and ensures ALTA does not climb or descend at the center stick 

position while flying in Manual Mode. A Hover Throttle setting that is too high or too 

low can cause ALTA to climb or descend when switching between Manual Mode

and Height Mode. 

Adjust the Hover Throttle setting by entering a stable hover in Manual Mode. Note the 

stick position, or have an assistant view the radio chart in the ALTA App to determine 

stick position. If ALTA hovers with the stick below neutral, decrease the Hover 

Throttle until ALTA hovers with neutral stick input. If ALTA hovers with the stick 

above neutral, increase the Hover Throttle until ALTA hovers with neutral stick input.

 NOTE

Hover Throttle will need to be adjusted when changing the 

overall weight of the system, or when moving between very 

different elevations.

NOTE

The ALTA App does not allow Hover Throttle adjustments while 

ALTA is flying.
