## PILOT OPERATION **HANDBOOK DJI**  **S -**  **1000/Z enmuse**  This book is offered in a format so that pilots can customize the checklists to their exact needs. Please print out this handbook, make notes while watching the video regarding the checklist, then change the wording and order to suit your needs. Then print out the revised form and laminate it in plastic. Carry it you’re your aircraft. Then use it every time you operate your aircraft. Keep the log books regarding the following: 1) Pilot flight time 2) Aircraft flight time 3) Aircraft maintenance and updates 4) Battery

usage, date put into service, voltage, mah vs time Print out and make readily available the error message legend of various flashing lights. Know what to do without hesitation should you observe warnings. Insurance is a must! Not only will it be expensive to repair your aircraft in the event of an incident, ifyou injure bystanders or damage other people’s property you are liable for damages which could run into the millions of dollars. One insurance company which currentl y writes policies on sUAS is www.Transportrisk.com Errors & Omissions should be sent to customerservice@tro ybuiltmodels.com . We will promptly update the POH for everyone to have the latest updates available. **KEY PARAMETERS**  Max Takeoff Weight: 24 lbs Weight with Zenmuse and all other equipment

– Ty

pical Maneuvering Speed

– 5 m/s
 POWER & POWERPLANT LIMITAT IONS o 40 Amps max per motor o 40 Amps max per speed control o 320 Amps max total o Do not exceed 80 - 90% discharge of rated battery capacity o Do not charge batteries which are warmer than air temperature o Allow batteries to cool after use before charging o Leave an air gap between batteries when multiple batteries are used simultaneously
 WEIGHT LIMITS o Takeoff Weight Max: 24 lbs  Must be checked prior to takeoff if any change in equipment is made
 CENTER OF GRAVITY LIMITS o 3mm from the center of any of the three pairs of arms  Must be checked before every flight to ensure batteries were installed in the proper location.  Check all 4 pairs of arms before flight
 MANEUVER LIMITS o This aircraft is intended for non- aerobatic operations o G - loading maximum: 2G
 TEMPERATURE LIM ITS o Operating Temp Range: - 10°C to +40°C o In cold temperatures  Keep IMU at room temperature if possible before the flight  Keep Batteries above 5°C before flight  Do not fly

with any frost or ice on the propellers o In warm temperatures  Batteries heat up when discharged  The higher the discharge rate the higher the temperature increase during use  At temperatures above 45°C, use of 2 or more batteries is required to lower the load on any one battery

pack to keep it cooler.
 WEATHER LIMITS o Li ght dust and light rain require the use of a shield for the electronics in the center section. o Li ght dust and light rain are acceptable for the unshielded motor and ESC.
 RANGE LIMITS o FUEL

## 13 © 201 4 Tro y Buil t Models , Inc
. Al l Rights Re s erved.  Fuel capacity is a primary limiting factor.  Flying into the wind will use more battery power to travel the same ground distance. Higher air speeds will be required to penetrate the wind which used more battery power. Take this into account when flying a mission.  Where possible, fl y upwind at the start of a mission and downwind at the end to avoid dep leting the battery

before returning to base. Have alternative landing sites available in case of emergency landing. o WIRELESS LINK  Wireless links will be stable in LOS (line of sight) in most conditions  Wireless links are always susceptible to shorter ranges due to  Atmospheric conditions  Other transmission devices in the area  Jamming  Antennas not aligned properly  Improper voltage  Antenna blockage from AV in certain positions  Multipath

– reflection off buildings or ground which cause multiple signals to arrive at different times and/or phase.

### SECTION **3 EMERGENCY**  **PROCEDURES**
 MOTOR FAILURE o Operation is possible with one motor/ESC/propeller failure  The two adjacent motors/ESCs will be increased in thrust automatically by the flight controller to overcome the loss  In cases where the airframe is highly loaded the maximum rating of 40 amps may be exceeded b y these two motors/ESCs  Operation should be terminated as soon as possible to reduce the possibility of damage to the remaining motors
 COMMUNICATION FAILURE o Video link failure  5.8 Ghz being the shortest wavelength in general AV use has the least ability to penetrate. This link should be the first to be lost.  It is best to lose video first! It is the least likely to cause a crash when it fails.  5.8 Ghz can lose link with little warning.  Ensure that the GCS station antennas are perpendicular to the AV. Do not point the antenna at the AV.  Yaw the AV to change the antenna position  Other links should still be good. Return back to the GCS until link is restored.  Transmitters produce heat when in operation. When overheated they may have thermal protection which interrupts use temporarily. Use of a heat sink or fan may be required especiall y with high ambient temperatures.  Higher gain antennas may be used, but do so with caution. High gain antennas are directional.  Multiple antennas using “diversity” can be used. Diversity is a device which determines the best signal, and uses that.  5.8 Ghz even at high wattages theoretically has less range than lower frequencies. Changing to 1.3 Ghz is an option, though there are other issues to be considered. o RC link failure  2.4 Ghz antennas can lose link with little warning.  Any thing in between the two antennas can cause temporary signal loss especiall y a person.  Hold the transmitter up in the air and walk in the general direction of the AV (aerial vehicle).  Ensure that the antenna is vertical. Do not point the antenna at the AV.  The failsafes on the RC link should be set so that the AV returns to home. Should this require a heading change, the antenna may move into a more desirable position and link will be restored.  The onboard equipment may block the signal. Yaw the AV so that the antennas point towards the GCS.  A LRS (long range s ystem) can be used as a permanent solution. This is higher in wattage and usually

on 433 Mhz. o Data Link Failure  900 Mhz do not lose link without some warning. When drop outs are noticed to increase in frequency

that is the limit of the range.

## 15 © 201 4 Tro y Buil t Models , Inc
. Al l Rights Re s erved.  If using 900 Mhz, this is on cell phone frequency . If a cell tower is nearby it can swamp the signal. 900 Mhz may not be usable in that area. Change to a different freq. or remain closer to the AV o LOW BATTERY POWER  Fail - safes can be set such that in the event of low battery power, either due to a failure or too long of a flight, the warning light on the AV will constantly flash amber. This is the first level of warning.  The second warning level is red flashing lights  Auto landing will occur when battery power is low. It may

land in a tree or a lake, so this is not desirable.  Landing with 80 - 90% of battery depleted is best. Therefore landing with 17,000 mah used and 3,000 mah remaining of a 20,000 mah battery is desirable. Batteries should be drawn down equall y when in use if they are both charged equall y and both in relativel y the same condition/age.  Do not mix partially

charged batteries. Onl y use completely charged batteries.  Over discharging a battery below 19.8V can permanently damage the battery . o GCS FAILURE  Takeover b y the external pilot should happen ASAP using the RC link.  Most often happens due to a low battery .  Keep a spare 3 cell LiPoly battery with the appropriate plug to plug into the charge jack for emergency

use. Most chargers are 19V output which is roughl y equivalent to a 4 - cell battery . 3 - cell batteries may work. o COMPASS CALIBRATION ERROR  If the compass is out of calibration the warning light will flash red. This is the same signal as low voltage. If the voltage is correct, there is a calibration error.  Recalibrate the compass following the instruction manual o FIRE  Fires can occur due to a short circuit or battery failure.  Disconnect the battery ASAP unless there is danger in doing so if there is any electrical issue.  It is not possible to put out a battery fire.  Do not attempt to put out a battery fire. Use a fire extinguisher to put out fires surrounding the battery . A CO2 fire extinguisher is better than the powder or chemical ty pe. CO2 does not leave a residue. Water can be used though it may cause other electrical component failures. o FORCED LAND INGS  If alternate emergency landing zones should be chosen ahead of time.  Be sure that the LZ is clear of people to avoid any incidents.  Land in the nearest LZ which is clear of people.  Announce your intentions of landing as loud as necessary to alert people of the incoming AV.

### SECTION **4 SET UP**  **SUGGESTIONS**
 ELECTRONICS BURN IN o We recommend that you put weights onto the landing skids to keep the copter on the ground and run the copter at about 70% throttle for about 2 hours to burn in the electronics. Most electronic failures occur in the first 2 hours of operation.  GPS/COMPASS MAST LENGTH o We found that the higher the mast, the better the GPS reception  Nex5N vs. Nex7 vs. Canon 5D vs. Panasonic GH3 o These cameras are excellent for stills, and very good for video. The best for video is the Panasonic GH4 with 4k capabilities. o We found that the Nex 5N takes exceptional quality stills and video, though most professionals use the Nex 7. The Canon 5D is better than the Nex7 due to its larger sensor. o Use the Panasonic GH4 if you primarily shoot video  RADIO SET UP o Follow the instructions in the manual o We prefer the switch assignment as shown in the checklists above though feel free to modify to your liking  COPTER COMMAND AND CONTROL o We recommend the use of a dual rate switch for main copter operation.  High rate

– used to initialize the motors. The flight controller will not engage unless it sees full down throttle, full left rudder, full left cyclic and full back cyclic. However, these may

be too high for normal flying. On high rate it is helpful to utilize fairl y high exponential to make the stick feel soft around center. Adjust to your preference.  Low rate

– used for typical flying. Set the end point adjustments such that full stick deflection offers the maximum speed required in normal flying. If conditions require higher flight speeds, switch to high rate. On low rate it is also helpful to utilize a small amount of exponential to make the stick feel soft around center. Adjust to your preference.  ZENMUSE COMMAND AND CONTROL o We recommend the use of a dual rate switch for gimbal operation.  High rate

– used to initialize the gimbal. The gimbal may not engage unless it sees full motion. However, these may be too high for shooting video smoothly . This is best for still photography so as to put the camera on target quickly. On high rate it is helpful to uti lize fairly

high exponential to make the stick feel soft around center. Adjust to your preference.  Low rate

– used for videography . Set the end point adjustments such that full stick deflection offers the maximum speed required for videography. If conditions require higher gimbal speeds, switch to high rate. On low rate it is also helpful to utilize a small amount of exponential to make the stick feel soft around center. Adjust to your preference. 

###  TIMERS 

### o Use of the countdown timer is a good backup method to ensure landing with battery power.  Set the timer for 20 minutes (or what you deem appropriate) and have it start when the throttle is over 1⁄4. Then adjust the timer upwards until the amount of battery used is about 80 - 90% of the total available. If using 2 0,000 mah batteries, a total of 17,000 mah would be the target. Set the timer such that you have a minute or so to land after

## 17 © 201 4 Tro y Buil t Models , Inc
. Al l Rights Re s erved.



###  BATTERIES the alarm sounds so that you have adequate time to return to base. Adjust to your

preference.
o Replace the transmitter standard battery with a Lipoly

battery to extend use times to 8 hours. Supplied batteries often last about 2 hours.

## 18 © 201 4 Tro y Buil t Models , Inc
. Al l Rights Re s erved. 

### NORMAL **PROCEDURES**
 PREFLIGHT CHECKLIST o Confirm all communication radios are operational  Radio with ATC  Radios with others in the group o Set a perimeter of 100 meters  Area must be clear of people to avoid collision o Check for overhead power lines and other obstacles to avoid o Check structural integrity  In event of prior crash, inspect all booms, props and motor mounts for excessive flex indicating structural fatigue/failure o Have a manual flight plan avoiding obstacles. o Load auto flight plan if using one  Be sure that the total flight time is under 10 minutes to avoid low battery o Clean lens  Remove lens cap o Ensure camera has SD card installed  Many flights have been wasted due to this! o Install batteries  Ensure that the straps are tight and the Velcro keeps the batteries from moving which will avoid a shift in the CG (Center of Gravity – or that it balances evenl y) o Check CG (Center of Gravity)  Lift the copter on each of the 3 pairs of arms. The copter should balance properly . If not, do not fly . Rearrange the equipment such that the CG is o IMU pointing forward  The Inertial Measurement Unit is set so that it must face forward o GPS/Compass installed, limited free play, pointing forward  This device must be installed with a screw to hold it in place. It cannot vibrate easily . If it does not point forward, the corrections in ATTI and GPS mode will be incorrect and it will crash. The FC will provide a warning with constant flashing white lights. o Level copter using a bubble level with front pointing in correct direction for course lock

– do not turn on  Keep in mind the best angle for pointing the landing gear in the direction that will keep the landing gear out of the shot when fl ying. o Turn on Pilot Tx o If using the rate gy

ro, set it at the correct position. This is usually a slider switch. Gains should have the range set from 200

– 350. Use the highest gain possible which does not cause oscillation. o Check Model Selection on Tx to be S800 o Throttle on Tx Down o Return to Home switch Off o Adjust gain to correct position (if required) o Manual Flight Mode Switch to manual (not ATTI or GPS mode) o Flight Path Switch Off

– Not Course or Home or POI o Check Tx battery

voltage (above 7.5v)  These settings above are required to initialize the copter properl y. If the switches are in the incorrect position, it will not initialize properly which may

cause some of the functions like course lock or GPS mode to not operate properl y.

## 19 © 201 4 Tro y Buil t Models , Inc
. Al l Rights Re s erved.  If the copter does not function properl y after takeoff, land immediately and disconnect the copter power. Then put all the switches in the proper position for initialization and turn the power back on to the copter. o Count down timer should be set to 20 minutes. This can be adjusted to your flying styl e. The timer should engage at 1⁄4 throttle and trigger an alarm at the proper time. Thi s is a backup alarm in case the indicator lights on the copter are not visible. o Turn on Photography Tx o Check Model Selection on Tx

– should read Zenmuse o Check Tx battery

voltage (above 7.5v) o HDMI switch Off o Freestyle switch Off (FPV On)  These settings above are required to initialize the Zenmuse properl y. If the switches are in the incorrect position, it will not initialize properly which may

c ause some of the functions like live video or gimbal operation to not operate properl y.  If the c amera or gimbal do not function properl y, disconnect the copter power. Then put all the switches in the proper position for initialization and turn the power back on to the copter. o Engage power to copter  Plug in the 2 battery

packs. Ty

pically the battery

p acks use red T - styl e connectors in a parallel wire harness. This Y -harness has a yellow connector. Itis preferable to connect the batteries to the Y -harness first, then plug in the yellow connector. This reduces (but does not eliminate) electrical arcing.  6 quick chirps should be heard confirming 6S LiPoly batteries are recognized by the ESCs.  Hearing less than 6 chirps indicates fewer cell battery packs are being recognized which is incorrect. Check for improper or damaged batteries. o Do not move or vibrate the Squadcopter until 30 seconds after full GPS Lo ck  Initial 3 red blinks is normal meaning no GPS lock. No red flashes indicates full GPS lock.  Continue with checklist as you are waiting for full GPS lock, but do not move the copter .  If the GPS takes more than 5 minutes to lock, there is a problem with the area. It is not receiving the proper signals from the satellites. GPS signals are weak, so trees, people, buildings, terrain, weather, have an effect. Move the copter into a more open area where it can more easily

see the satellites. o Check Copter Voltage from both Tx’s (transmitters)  The transmitters receive a signal from the corresponding receivers. The voltages are regulated to about 5v. If the voltage is below 4.4v or above 6v do not fl y. There may be power regulation issues. The receivers cannot work outside this voltage consistently . Also there is some issue if the voltage is outside that range which should be resolved before fl ying. o Engage Attitude Mode

– Must achieve double amber flash o Engage GPS Mode

– Must achieve double purple flash o Engage course cock mode

– Must achieve double green flash o Disengage course lock mode. Must achieve double purple flash. Stay in this mode until just prior to takeoff, after takeoff at any time, or do not use. o Do not engage motors. Set throttle to center position. Must achieve single purple flash when in GPS mode.  To verify

that the sticks are all centered properl y:

Trim the roll (the stick located on the right side of the transmitter when moved to the right and left) to the right, counting the number of clicks until a double flash occurs. Then center the trim. Then move the trim to the left, counting the number of clicks until a double flash occurs. An equal number of clicks should be counted each side of center.  Do this check for the 3 stick movements other than throttle.  Center the trim such that when the stick is in the neutral position that there are equal numbers of clicks in each direction. This ensures that when the sticks are neutralized that the flight controller will recognize this signal and engage GPS mode. o Calibrate GPS/Compass before the first flight each day or if receiving continuous red blinks or continuous white blinks.  Flip the GPS mode switch 7 times very quickly from manual to GPS. End with the switch in the manual position. The indicator light will be blue. Rotate the copter about 1.5 turns in a horizontal position. A green flashing light indicates that this is complete. Then hold the copter vertically and rotate about 1.5 turns. A white flashing light indicates that this is complete. Repeat if necessary until this is completed. o After calibration, reset the copter b y cycling battery with copter pointed in the correct heading for course lock. o Engage Camera o HDMI switch On  This will stop video from playing on the back of the camera and will send the video signal to the video transmitter via the HDMI connection. o Freestyle switch On (FPV Off)  This allows the camera to be operated freely through the transmitter o Verify

camera operation  Operate the shutter  Set the focus to auto or manual. Manual setting is usually set to infinity

to stop constant focusing of the camera. o Verify

data link if installed  Roll the copter about 45 degrees on its side b y lifting one side of the copter and resting one side of the landing gear on the ground  A corresponding roll should be seen on the gauge.  If the copter is rolled to the right, it will appear on the gauge that the horizon rolls to the left

– not the right because the view from inside the copter is that the horizon rolls the opposite direction of the copter. o Verify

altitude is about 0 via gauge on computer  If it is not about 0, the altitude settings for the waypoints will be off by this amount. This could cause the copter to fly at 10 meters or 30 meters if the waypoint is set for 20 meters and the altitude is off b y 10 meters one way or another. If the copter thinks it is at 10 meters when it is on the ground, then it will only rise 10 meters above the ground to achieve what it believes it to be 20 meters above the ground.  The altitude can be reset using the ground control software b y going to altitude offset. o Alternate Emergency

Landing Sites Established

 NORMAL TAKEOFF o Confirm clear for takeoff with ATC  Necessary

if within 5 miles of an airport

– Double purple flash when the throttle is down. o Switch to Course Lock flight mode if required. Purple flashes are replaced with green flashes. Flying in course lock is not required, but helpful in many instances. o Announce loudl y: “CLEAR PROP” o Move both of the sticks to the bottom left corners to engage the motors. Within 1 second move the throttle up 1/8

– 1/4. The copter should not lift off until about 1⁄2 stick is reached. o Verify

data and video links before lifting off. If any thing is not working properly, move the throttle stick to low to disengage the motors and determine a solution. o If all flight checks are passed, announce loudly: “TAKING OFF” o Advance throttle to about 3/4. Copter must jump off of the ground to avoid one skid coming up before the other skid, and the skid on the ground getting caught and flipping the copter over sideways. o Ascend to 3 meters. Then decrease throttle to 1⁄2 to engage the GPS hold. o Verify

links, GPS, Attitude, etc. Should be single purple flash. o Verify

that the copter is holding position within .5m in all directions. o Verify

camera operation o Verify

course lock is operational by rotating 90 degrees and pushing forward on stick. o Verify

copter stability . If unstable, land and reset gains, recalibrate, or retest as necessary . o Proceed with manual mission or o For autopilot operation  Ascend to 10 meters  Command AVO to proceed with mission.  Pilot should say

“It’s yours”  Response from AVO “I have it” o Manual pilot/observer must monitor the informational LED and be ready to take over in manual mode when necessary .  White flashes indicates flight controller issue  Amber flashes indicates low battery  Red flashes indicate loss of GPS or severe battery condition  Quick decisions are required when red flashes are indicated  10 seconds or more of loss of GPS signal will stop way point guidance and any GPS hold and put into manual mode.  Red indicator light battery warning requires immediate landing o Manual pilot to request copter flight battery voltage readout from AVO periodically .  Reset the first and second indicator lights as required for your set up.  When recharging the batteries, the goal is to put 4,000 mah into a 5,000 mah battery pack. Adjust the voltage warnings to your style of flying.  Also use the countdown timer on the transmitter. This gives a good indication of battery level because the current used is fairl y constant from flight to flight.

 POST LANDING o Note flight time from transmitter. Write this down in the log book. o Note battery

power used during the flight. Write this down in the log book. o ALWAYS disconnect the main power to the AV first, then turn off the transmitter.

### SECTION **5 PERFORMANCE** 
 FLIGHT TIMES o The AV is designed to hover at high efficiency . Hovering is much less efficient than flying on a wing, thus flight times are low compared to fixed wing aircraft. o All the weight of the AV is supported by power from the batteries. As the batteries are used in a flight, the amount of power available decreases. Therefore the power reserve is constantl y decreasing as the battery

is being used. Thus loading a rotorcraft above its limit is not recommended. While the AV may have enough power to lift off initially on a full charge, the power reserve at partial charge may be too low to allow for maneuvering and will result in a crash. o High lateral speeds will add lift to slightly improve effici ency . The rotors act similar to fixed wings at higher speeds. This increase in efficiency may be negated by

the increased power consumption of forward flight. o High winds or gusts decrease efficiency /flight time. The motors work harder to hold position. o As weight increases flight times decrease.

 WIRELESS TRANSMI SSION o Refer to the specific manuals for performance ratings. o Wireless communications utilized provide acceptable communication for LOS. o In general:  LOS is required  The higher the GCS antennas, the better the range  Any freq. at may

have severe degradation due to location to other admitters such as cell towers  RSSI(Received Signal Strength Indication) should be monitored for indication of communication drop out.

 CG 

### SECTION **6**

**WEIGHT AND BALANCE EQUIPMENT**  **LIST** o CG is critical to the efficient operation of any AV o When components are shifted, the CG will be altered. o The main components which are moved on a regular basis are the sensors and the batteries. o The sensors are typicall y in the front of the AV, and the batteries are located in the correct position to offset all the components on the AV. o The CG must be tested after any change to the components or their placement. o The CG should be tested by lifting the UV with fingers on the bottom of the arms. Check all 3 pairs of arms. The CG should be no more than 2mm off in any on the 3 checks. The closer the CG is to the centerlines of the arms the more efficient and the more stable the AV will be.  WEIGHT o Weight is critic al to the operation of any aircraft o Weight is especiall y critical to a rotor wing aircraft. At full throttle the motors have a finite amount of thrust. All the weight is lifted b y the battery power, there is no wing to assist in providing lift. o As the batteries are operated, they lose power. At full charge they have about 25v. At 20% remaining capacity the y have about 21v. This is a loss of 8% of the power available which is significant. o Do not overload the aircraft or there will not be sufficient reserve power to maneuver at low battery levels.

### SECTION **8 HANDLING, SERVICE AND**  **MAINTENANCE**
 PROPELLER CARE o Propellers must be checked each flight for nicks or cracks o Propellers are designed to last indefinitely if they do not impact dust, dirt or more.
 BATTERY CARE AND USE o Refer to instruction sheet included from the battery manufacturer. Ty

pical information follows. o Batteries are highl y flammable and can explode, especially when fully charged. Improper charging, vibration, impact, high discharge, etc. can lead to explosion and fire. Batteries must be charged under constant supervision and using proper precautions. o Batteries fully

charged must be handled with extreme care. o Any battery which puffs up is considered damaged and must not be used. It is in a dangerous state. Never charge a puffed up battery . o Any battery which holds less than 80% of its rated capacity should be discarded. o Cycle test each battery after every

50 cycles or if a battery

is suspected to have lost as significant amount of its capacity to determine the current capacity. o Properly

dispose of batteries. First discharge the b attery full y using a battery cycler. Bring to a recycler such as a home improvement store. o Always charge flight batteries under “balance” mode. o Flight Battery

Recommended Charge Rate: 1C which takes approximately 1 hour to charge o Flight Battery

Maximum Charge Rate: May exceed 5C. Charge rates higher than 1C will decrease life cycles. Maximum charge rating per the manufacturer will provide 300+ cycles. Use the lowest charge rate which is practical. o Battery

Rest Time between discharging and charging: 30 minutes minimum, 1 hour maximum. o Do not charge if the battery is more than 2°C warmer than ambient, especially if the temperature is above 20°C. The outer surface is cooler than the inner core after use. Damage will occur when charging a warm battery . o Recommended Battery Discharge Amount: 80%. Using more of the capacity of the battery will decrease the life cycles o As battery

temperature approaches freezing the capacity of Lithium Poly

mer batteries decrease. Keep warmer than 5°C before installing into the UV (unmanned vehicle). o Battery

capacity decreases at higher discharge rates. Using more batteries decreases the discharge rate of each battery thereby extending individual battery capacity slightly . o Lower discharge rates improve the life cycles. o Batteries are rated at greater than 300 life cycles. 1,000+ life cycles are possible. o Batteries must not be stored above 60% charged state for extended periods. o Batteries should be stored below 25°C for extended periods o Store batteries between 40% - 60% ch arged state. Fully charge just before use. o Fully charged batteries which are not to be used within 24 hours should be discharged to 40%

- 60% charged state using the battery discharger. o Using more than one battery at a time requires the proper wiring harness so that the voltage is no more than 25.2V. Over voltage will cause serious damage to electrical equipment.
