TUNING ALTA 

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

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. Default tuning vaLues are 

incLuded in Appendix A, Default Tuning Vatues. 

Parameters fall into three categories - Attitude, Height and Position. Typically, 

tuning should take place in that order, ensuring Attitude parameters are set first, 

then moving to Height parameters, and finally Position parameters. 

Tuning should take place as an iterative process by making only small changes, test 

flying the changes, observing the new flight behaviors, and repeating. Only tune a 

singte parameter at a time during this process for best results. 

To tune ALTA, open the ALTA App and select Configurations - ~> Aircraft Dynamics. 

~ WARNING 

Tuning can change the fundamentat 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 smalt increments and with caution. Always test new tuning 

configurations in open areas away from people or obstactes. 

;] NOTE 

The ALTA App only altows tuning while ALTA is on the ground. 

ATTITUDE TUNING 

Attitude tuning adjusts how ATLA responds to control inputs and disturbances. 

Attitude directly controts responsiveness and changes ALTA's fundamental flying 

behaviors. Attitude must be tuned acceptably before tuning height or position 

parameters. 

When tuning attitude, the primary parameter to change is Stiffness followed by 

Strength. 

STIFFNESS 

Stiffness is adjusted for pitch and roll simultaneously, and yaw independently. It 

changes how stable ALTA is in these axes and is the primary variable to adjust when 

KEN "" = I USER MANUAL 58 
tuning. When tuning Stif€ness first, or making large stiffhess changes, Hotd Strength 

should be set to a low. non-zero value. 

Higher Stiffness values give more responsive control. Values that are too high can 

cause instability or oscillation. 

zt WARNING 

Excessively high stiffness values can cause ALTA to become 

unstabte and difficutt or even impossibte to controt. 

Lower Stiffness vatues give less responsive controt. Vatues that 

are too tow can cause a vague or disconnected control response. 

HOLDSTRENGTH 

Hold Strength controls how much ALTA will try to maintain a pitch/rott 

angle command, or a yaw heading command. It is adjusted for pitch and roll 

simuttaneously, and yaw independentty. A higher Hold Strength setting will give a 

faster controt response and a more responsive feet. However, values that are too 

high can cause ALTA to overshoot pitch or rolt commands, or even cause instability. 

ZL WARNING 

Excessively high strength values case cause ALTA to become 

unstabte and difficutt or even impossible to control. 

Typically, this setting will not need to be changed from 

the default vatue, and only then in smatl increments. 

HEIGHT TUNING 

Tuning height parameters will adjust the control feel of ALTA's height control while 

in Height and Position modes (for additional information on flight modes, see the 

Ftight Controtter Modes section of this manual). Tune height parameters only after 

satisfactorily tuning attitude parameters. 

Similar to attitude tuning, stiffness is the primary tuning parameter. 

If switching to Height Mode causes ALTA to fly in an unstable manner, switch back to 

Manual Mode, land and try reducing the vatues of height tuning gains if they are very 

high, or increasing them if they are very low. 

VERTICAL STIFFNESS 

Vertical Stiffness Gain modifies the vertical stability of the ALTA in Height mode. 

0 >`»,aM I USER MANUAL 59 
Decrease this value if ALTA experiences vertical oscillation or vibration. Increase 

this value if ALTA is sluggish while accelerating to a desired climb or descent rate in 

Height mode. 

HOLDSTRENGTH 

Hold Strength Gain tunes how much ALTA will attempt to stay on a desired altitude 

in Height Hotd mode only. A higher value will result in height being held more 

precisely. Too high of a value can cause ALTA to overreact to winds, gusts or 

turbulent air. 

CLIMB RATE STRENGTH 

Climb Rate Strength adjusts how much ALTA will attempt to maintain a desired 

climb rate. Higher values will result in a more direct feel between pilot climb or 

descent commands and ALTA flying behavior. However, values that are too high may 

cause instabitity. 

POSITION TUNING 

Tuning position parameters will adjust how well ALTA maintains a desired ground ~ 

speed or a position over the ground. Similar to attitude and height tuning, the 

primary value to adjust is stiffness. 

HORIZONTAL STIFFNESS GAIN 

This changes the horizontal stability of ALTA. Higher values increase ALTA's 

resistance to wind gusts or turbulence from moving ALTA off its target position. 

Values that are too high can cause instability of ALTA. 

HOLD STRENGTH GAIN 

This adjusts how much ALTA will attempt to maintain its place over a target position. 

A higher value will result in position being held more precisely. If too high, positional 

instability can result, causing ALTA to fty past a target position. 

USER MANUAL 60 
ALTA FLIGHT PARAMETERS 

Flight Parameters are different from tuning parameters in that the flight 

characteristics of ALTA will not change with their modification. However, they can be 

used to select neutral points using trim, or to set maximum or minimum values. 

ATTITUDE 

PITCH AND ROLL TRIM 

Use Pitch and Roll trim settings to correct for tendencies of the ALTA to pitch or roll 

with a neutrat control input. 

Use the in-app pitch and rotl trim settings instead of radio controller trim features 

as large radio controller trims could prevent position hold from engaging at neutral 

stick positions. 

MAXIMUM PITCH/ROLL ANGLE, 

This sets the maximum angle the ALTA will be allowed to fly in alt modes and in all 

flight conditions. 

MAXIMUM YAW RATE 

_ This is the maximum rate the ALTA will yaw (pan) when at full stick deflection. 

HEIGHT 

HOVERTHROTTLE 

Hover Throttle is a 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 Throttte setting that is too high or too low can cause ALTA to 

climb or descend when switching between Manual and Height Modes. 

~ NOTE 

Hover Throttle witt need to be adjusted when 

changing the overall weight of the system, or when 

moving between very different elevations. 

Adjust the Hover Throttle setting such that during a stable hover the required 

throttle position is at middle stick, or about 1500 Ns in the App radio chart. Increase 

Hover Throttle if hover occurs above center stick, and decrease if hover occurs 

A_., , I USER MANUAL 61 
betow center stick. 

Alternatively, if ALTA climbs when switching from Manual to Height mode, increase 

hover throttle, since a climb indicates a stick position that is higher than neutral in 

Manual mode. If ALTA descends, decrease hover throttle, since a descent indicates a 

stick position that is lower than neutral in Manuat mode. 

~ NOTE 

The ALTA App does not attow hover throttte 

adjustments while ALTA is flying. 

MAXIMUM CEILING 

This adjusts the highest attitude the ALTA is allowed to climb from its starting point 

while in Height or Position modes. If the maximum ceiling is exceeded in Manual 

mode, the Status Light will illuminate white. 

~ 

MAXIMUM CLIMB-RATE 

This sets the maximum speed ALTA witl ctimb at full throttte stick deflection in 

Height Mode or Position Mode 

If Climb Rate Clamp is mapped to an radio controller channel, the parameter will 

adjust the fastest climb speed availabte to the Climb Rate Clamp feature. 

GPS HEIGHT CORRECTION 

With GPS Height Correction On, SYNAPSE witt use both barometer and GPS sensor 

measurements to determine its attitude. It can be useful for assisting in windy or 

gusty conditions, but requires good GPS reception. It is recommended to keep this 

enabled unless GPS reception is problematic. 

POSITION 

MAXIMUM G 

This sets the total maximum acceleration, in G's, that the controlter will place on the 

airframe. It is recommended to use lower G settings with heavier payloads. 

This setting has no effect in Manual mode. 

MAXIMUM GPS ANGLE 

This sets the maximum pitch and roll angle the ALTA may fly under Position mode. 

This wilt not override the Attitude Maximum Pitch/Roll Angle. Instead, ALTA wilt 

~ ALTi°k I USER MANUAL 62 
follow the lower of these two limits. 

MAXIMUM GPS SPEED 

Max GPS Speed sets the maximum speed ALTA will fly across the ground at full stick 

deflection in Position Mode. 

If Velocity CLamp is mapped to an RC transmitter channel, the parameter wi_ll adjust 

the fastest ground speed availabte to the Velocity Clamp feature. 

RANGE 

Range sets the maximum distance ALTA may fly away from the home point white 

in Position mode. If the range is exceeded in Manual mode, the status light will 

ilLuminate white.

FLIGHT CONTROLLER MOOES 

_ 

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

Position Mode. They are selected with the Mode Switch 

~ CAUTION 

Always neutratize control inputs when 

switching between control modes. 

MANUAL MODE 

In Manual Mode, ALTA will only stabilize its attitude. At neutral control input (middle 

pitch and roll stick position), ALTA wilt 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. Converse.ly , 

the lower the throttle stick position, the faster ALTA wilt descend. 

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

ALTA witl maintain a target altitude and try to correct for drift. If a disturbance 

moves ALTA away from this target altitude, ALTA witl climb or descend to return to 

the target altitude. 

POSITION MODE 

Position Mode changes the pitch/roll stick behavior to command ground speeds. 

Pitch and rott stick deflection will command fore/ aft and teft/right ground speeds 

respectively. Controlling altitude in Position Mode is the same as in Height Mode. 

With pitch and roll controls centered, ALTA wilt 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 automaticalty revert to Manual Mode. 

i USER MANUAL 65 
(0 CAUTION 

Ftight using Position Mode in areas of degraded GPS signat, 

such as near buildings or under dense tree cover, is not 

recommended. The automatic reversion to Manual Mode 

can cause unexpected, abrupt changes in flight behavior. 

RETURN-TO-HOME 

Return-To-Home Mode witt 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 atso be used to set a new Home Point. See the Radio Mapping section in this 

manual for more information on setting up the Home Switch. 

RTH can be initiated manuatty 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 

pitot will maintain control of ALTA's altitude the entVe time. ALTA will not Autoland 

if an adequate signal is detected. The pilot can cancel the RTH procedure by 

commanding a pitch or roll command or by retuning the Home Switch to the middle 

position. The Mode Switch must be in Position Mode to activate RTH manually. 

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. Finalty, upon reaching the home position, ALTA wilt begin 

Autoland.

AUTOLAND 

The Autoland function will command ALTA to hover for 10 seconds and witl then land 

in place. This 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 the Safe Height 

at the Maximum Descent Rate. After reaching this height, ALTA's descent witl slow to 

the Autoland Descent Rate until landing. 

HOME SWITCH 

The home switch has three settings, Set Home, RTH Off and RTH On. 

SET HOME 

Set Home sets a new home point at ALTA's current position. This could be useful for 

setting a point away from the initialization point, such as if the ALTA were started 

underneath an overhang or a tree. 

A new home point can only be set within 20 meters of ALTA's starting point. 

s Momentarily moving the Home Switch to the Set Home positiqn sets a new home 

point. When a new home point is set, the Status Light will turn white to indicate the 

new home point was successfully set. 

RTH OFF 

This is the normal switch position and does not initiate an RTH command. 

RTH ON 

This manually initiates the RTH function. In a manual RTH, the pilot maintains 

control of height while the SYNAPSE will command ALTA's position over the ground 

to the home point. 

ARM ENABLE SWITCH 

The optionat Arm Enable Switch altows for added safety while working around and 

flying ALTA by disatlowing arming during ground handling or disarming during 

flight. To set up an Arm Enable Switch, refer to Mapping Channels or the ALTA User 

Manuat. 

If used, the Arm Enable function should be mapped to a three-position switch.

compass sensing and data logging. 

The blades should be checked for damage, including nicks and scrapes. If a prop 

has been nicked enough such that it catches a fingernail, it shoutd be replaced. 

Bolt tightness should be checked by rotating the blade about its length (blade pitch 

up and downl. There should be no slop, and if there is, the bolt and nut shoutd be 

tightened until the slop is removed. There should be no slop between the prop hub 

and the motor. 

~ RXM I USER MANUAL 75 
Motors should spin freely, and there should be no grinding or scraping sound from 

the motor. The inside of the motor should be free of debris. 

Atways turn on the radio controller before plugging in ALTA. Follow the battery 

installation guidance in the Battery Installation section of this manual for battery 

installation instructions. 

While the SYNAPSE flight controller initializes, keep the ALTA as stable as possible. 

Wedging a foam. prop protector between the stationary gimbal or landing gear and 

the ALTA frame can'be used to stabilize ALTA from spinning during this process. 

;] NOTE 

If ALTA moves during initialization, it many not boot properly. 

When it is impossible to initialize ALTA without movement (such as booting on a 

boat), Motion Booting can be used. It is not recommended to use Motion Booting 

regularly. 

During initialization, the Status Light will quickly flash a sequence of red and 

white lights. At the erxl of this process, it will begin slow flashing white, indicating ' 

SYNAPSE is ready for arming. The Orientation Lights will also begin flashing 

green. Verify that all six motors are flashing green, indicating all ESCs initialized 

successfully. 

Verify that there are no flight warnings by connecting to ALTA via the ALTA app and 

checking on its status from the App. For mtire information, see the ALTA App section
