**DJI Inspire 1**
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. Use it every time you operate your aircraft. Keep the log books regarding the fo llowing: 

### 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 currently writes policies on sUAS is www.Transportrisk.com Errors & Omissions should be sent to customerservice@troybuiltmodels.com. We will promptly update the POH for everyone to have the latest updates available.

 MANEUVER LIMITS o This aircraft is intended for non-aerobatic operations o G-loading maximum: 2G

 TEMPERATURE LIMIT S 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
 WEATHER LIMITS o Light dust and light rain require the use of a shield for the electronics in the center section. o Light dust and light rain are acceptable for the unshielded motor and ESC.

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

 RANGE LIMITS o FUEL 

###  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, fly upwind at the start of a mission and downwind at the end to avoid depleting 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.

# 18 © 201 4 Troy Buil t Models , Inc
. Al l Rights Re s erved. **SECTION 3**  **EMERGENCY PR** **OCEDURES**

 MOTOR FAILURE o Operation is not possible with one motor/ESC/propeller failure

 COMMUNICATION FAILURE o Video/data 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. 

###  Itis 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 especially with high ambient temperatures. 

###  5.8 Ghz even at high wattages theoretically has less range than lower frequencies.
o RC link failure 

###  2.4 Ghz antennas can lose link with little warning. 

###  Anything in between the two antennas can cause temporary signal loss especially a person. 

###  Hold the transmitter up in the air and walk in the general direction of the aerial vehicle (AV). 

###  Ensure that the antenna is vertical. Do not point the antenna at the AV. 

###  The failsafe 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.
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. This is the first level of warning. 

###  The tablet GCS will calculate the amount of charge left and warn you when it is time to return to home. Do not let this be your only warning, monitor you usage and know when you need to return home. 

###  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 3,600 mah used and 400 mah remaining of a 4 ,000 mah battery is desirable.
o GCS FAILURE 

###  Takeover by the external pilot should happen GPS failure occur ASAP using the RC link. 

###  Most often happens due to a low battery. 

###  Keep a spare 3 cell LiPo battery with the appropriate plug to plug into the charge jack for emergency use. Most chargers are 19V output which is roughly equivalent to a 4 -cell battery. 3 -cell batteries may work.

o COMPASS CALIBRAT ION ERROR 

###  If you need to recalibrate the compass, follow manufacture instructions.
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. 

###  Itis 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 type. CO2 does not leave a residue. Water can be used though it may cause other electrical component failures.
o FORCED LANDINGS 

###  Alternate emergency landing zones should be chosen ahead of time. 

###  Be sure that the LZ is clear of people to avoid any injuries to bystanders or 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.

# 20 © 201 4 Troy Buil t Models , Inc
. Al l Rights Re s erved. **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.

 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

 TIMERS o Use of the countdown timer is a good backup method to ensure landing with battery power. Set the timer for 15 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 4,000 mah batteries, a total of 3,6 00 mah would be the target. Set the timer such that you have two minute s or so to land after the alarm sounds so that you have adeq uate time to return to base. Adjust to your preference.

# 21 © 201 4 Troy Buil t Models , Inc
. Al l Rights Re s erved. **NORMAL PROCEDURES** 

 PREFLIGHT CHECKLIST o Confirm all communication radios are operational 

###  Radio with AT C and phone number back up available 

###  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 (when function available) 

###  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 S D card installed 

###  Many flights have been wasted due to this! o Install battery 

###  Ensure that the battery is securely in place o Check Center of Gravity (CG) 

###  Lift the copter on each of the 3 pairs of arms. The copter should balance properly. If not, do not fly. Make adjustments as needed 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 flying. o Turn on Pilot Tx o Throttle on Tx Down o Return to Home switch Off o Manual Flight Mode Switch to manual (not ATTI or GPS mode) o Flight Path Switch Off

– Not Course or Home o Check Tx battery voltage (above 7.5v) 

###  These settings above are required to initialize the copter properly. 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 properly. 

###  If the copter does not function properly 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 correctly. This can be adjusted to your flying style. The timer should engage at 1⁄4 throttle and trigger an alarm at the proper time. This is a backup alarm in case the indicator lights on the copter are not visible. o Turn on Photography Tx o Check Tx battery voltage 

###  If the camera or gimbal do es not function properly, 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 Do not move or vibrate the quadcopter until 30 seconds after 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

# 22 © 201 4 Troy Buil t Models , Inc
. Al l Rights Re s erved. 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 Engage Attitude Mode

– Verify tablet reflects ATTI mode o Engage GPS Mode

– Verify tablet reflects GPS mode o Engage course cock mode – Verify tablet reflects course lock mode o Do not engage motors. Set throttle to center position. o Calibrate GPS/Compass before the first flight each day or if receiving calibration errors .



###  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 flash . 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 green flashing light indicates that this is complete. Repeat if necessary until this is completed. o After calibration, reset the copter by cycling battery with copter pointed in the correct heading for course lock. o Verify camera operation 

###  Operate the shutter 

###  Check the focus. o Verify data link 

###  Roll the copter about 45 degrees on its side by 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 by 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 by 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 

###  ATC clearance is required days or weeks before flying. o Engage GPS mode

– Verify on tablet . o Switch to Course Lock flight mode if required. Verify on tablet . Flying in course lock is not required, but helpful in many instances. o Announce loudly: “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 anything 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 (9 feet) . Then decrease throttle to 1⁄2 to engage the GPS hold.

# 23 © 201 4 Troy Buil t Models , Inc
. Al l Rights Re s erved.

o Verify links, GPS, Attitude, etc. Verify on tablet . 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 if desired o For autopilot operation (when available) 

###  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 on the tablet and be prepared to take over manual control as necessary.
 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. o Check motor temperatures by touching them with your fingers. Any motors which are excessively hot should be further inspected and possibly replaced. o Check battery temperatures by touching them with your fingers. Battery temperatures should not be hot to the touch. Battery temperature s should be slightly above ambient. o Inspect all components especially the propellers for wear. o Note in logbook which batteries were used to calculate life cycle.

 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 constantly 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 efficiency. 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.

 WIRELESS TRANSMISSION 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. 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 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 both pairs of arms. The CG should be no more than 2mm off in any of the 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 critical to the operation of any aircraft 

### o Weight is especially critical to a rotor wing aircraft. At full throttle the motors have a finite amount of thrust. All the weight is lifted by 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 they have about 21v. This is a loss of 8% of the power available which is significant.

###  WERELESS COMMUNICATIONS 

### o Re fer to the specific manuals for performance ratings. 

### o Never power a video transmitter or receiver without an antenna connected or overload failure will occur. 

### o Wireless communications utilized provide acceptable communication for LOS. 

### o In general: 

###  LOS is required. 

###  Lower frequencies penetrate objects such as trees better than higher freqs. 

###  Lower freqs have longer range than high freqs 

###  Higher freqs can transfer more data than lower freqs 

###  The higher the GCS antennas, the better the range and reception 

###  Any fre q may have severe degradation due to location or to other transmitters such as cell towers 

###  Range must be constantly monitored. 

###  Alternate freqs may be utilized to improve link/range.

###  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. 

### o Batteries are highly 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 battery fully using a battery cycler. Bring it 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 (3 ° F) warmer than ambient, especially if the temperature is above 20°C (68 ° F) . 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 Polymer batteries decrease. Keep warmer than 5°C before installing into the UV (unmanned vehicle). 

### 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 (77 ° F) for extended periods 

### o Store batteries between 40% - 60% charged 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.
