### January 10, 2016 Petition for Exemption Rick A. Ervin 14837 Hill Rd Klamath Falls, Oregon 97603 Phone: 541-602-4550 Email: ricker83@gmail.com U.S. Department ofTransportation, Docket Operations West Building Ground Floor, Roomwl2-140 1200 NewJersey Avenue, SE., Washington, DC 20590 Ii

I, Rick A. Ervin, hereby submitthis petitionfor exemptionunder Section 333; FAA Modernization andReform Actof2012, Public Law 112-95 FEB. 14, 2012, Section 333. I kindly request this exemption in orderto operate my UA V/U AS, Immersion RC Xu Gong v2/Pro Quadcopter Aircraft, for thepurpose ofaerial data collectioninorder to provide services for profitto include aerial photography, aerial cinematography, aerial filming and photography for real estate, constructionfirms, agricultural modeling, crop monitoring operations, aerial mapping, special events 

### to include butnotlimited to weddings, private orpublic parties/events, business advertising, promotional events, geological surveying, and environmental studies. The ability to provide these services to other local businesses and individuals inmy community will benefitthemby opening up opportunities they otherwise did nothave before. Traditional methods ofaerial photography/videography are simply not viable options for the average consumer as they are costly and involve greater risks to everyone involved; i.e. the use oflarger aircraft carrying people and flammable fuel. By utilizing the UAV/U AS, the same results canbe achieved withmuch safer conditions. Priorto each flight/operation ofthe UAV /UAS, I will conduct a Pre-Flight Safety Inspection. Only the manufacturer's authorized repair facilities/providers will perform any and all repairs. Flights will nottake place over densely populated areas orprivate property withoutthe owner's permission. TheUAV /UAS will only be operated within visual line ofsight and will notbe flown near airports or above 400 feet AGL. The FAA can be confidentthat operations ofthis UAV/UAS will achieve at leastthe equivalent or greater level ofsafety. The UAV weighs less than 55lbs. All flights will beterminated at 20% ofremaining battery life, which canbe monitoredremotely, along with otherlive inflight data including altitude, airspeed, GPS location, and groundspeed. The speed ofthe UA V/U AS will never exceed 25 MPH at any giventime during operation. All safety factors will be diligently and closely followed at all times. All component recommendations, precautions, and suggestions inthe UAV /U AS instruction manual will be strictly followed and never deviated from. The Immersion RC XuGong v2/Pro manual is attached to this petition. All flights will have a crewofatleast 2 people. This crew will consist ofa spotter and a FAA certifiedpilotwith a currentprivate pilot's license who has extensive experience flying this type ofUAV/UAS to ensure complete control and maximum safety during all phases ofoperation. Safety will be the primary factor at all times.**:~·;** !') LI (j

### I have safely and successfully operatedradio-controlled aircraft for over 20years without any incidents. These aircraft include: large-scale gas powered airplanes, electric EDF jets, electric aerobatic aircraft, quadcopters, helicopters, indoor micro-size aircraft, selfdesigned scratchbuilt aircraft, gliders, and I have recreationally operated various aircraft with first-person-view video systems including powerful quadcopters and fixed wing aircraft. Also, I have a currentprivate pilot's license and a current class III medical certificate. I have safely logged over 370 hours operating as PIC without any incidents in multiple types ofaircraft. Primarily, I fly a L-21B Supercub on a regular basis, operating in and outofClass D airspace while communicating with ATC. I have a very thorough understanding for all classes ofairspace, weather, FAR's, and limitations. Aviators who knowme, consider me to be a safe, responsible, competent, knowledgeable, and skilled pilot inbothprivate aviation andradio control aviation. The specific sections of 14 C.F.Rfrom whichI am seeking exemption are as follows: 14 C.F.R. Part 21; 14 C.F.R. 45.23(b); 14 C.F.R. 61.101(e)(4), &

# Preparation Before starting assembly ofthe XuGong it is highly recommended to wash the carbon fibre parts in water, to remove any fibres which might remain afterthe production process. These plates are pre-washed in thefactory, but a second washing after shipping is recommended. Dry the plates completely before starting assembly. 

# Step #1: Frame Assembly The first step in the assembly of a XuGong v2/Pro is to assemble the carbon-fibre frame, and mountthe gimbal onto it. Note: Unlike the v1 version ofthe quadcopter, the frame can be completed before the electronics are installed. The largerhole above the flight controller, and the largerholes in the bottom 

### of the frame, allow electronics 

### to be installed without removing frame plates.



### 8• f



### 9The frame is assembled using our custom 'T-Nuts'. These consist of a plastic retaining part, an aluminium 'nyloc' M3 nut, and an aluminium M3 bolt.

The nut may be inserted intothe retainer, with the flat part ofthe nut facing the flat part ofthe retainer. This pair is then inserted into the 

### 'T' hole in the first plate, and the screw inserted through the hole in the second plate. The resulting structure is extremely strong, and will easily survive even the most serious of crashes, protecting the electronics that it houses. Be careful with the orientation ofthe front gimbal-bulkhead plate, which has two mounting holes which line up with matching holes in the back ofthe gimbal. Pre-inserting all ofthe nut/retainer assemblies into all T-Nut slots in a part will speed up assembly:

Tips: It's a/so a good idea to insert the rubber feet on the bottom plate at this point. It can be almostimpossible to do it once the frame 

### is assembled. Careful not to twist the rubber feet in carbon plate as it will cut the rubber



### 10It is advisable to install the gimbal atthis point, since the screws are a not easyto access once the frame is assembled. WARNING: when installing the gimbal make sure to use the screws that come with it. Pay special attention to the ones used to mountthe gimbal on thetop plate (M2x5). Using longer screws maycause electrical shorts.

Before completing theframe, it is highly advisable to mountthe lower part ofthe Naza GPS support, since screws must be installed from insidethe frame.

,,J% 

# L.f:l WARNING: Never install the GPS mounting screws with thethreaded end ofthe screw in the battery compartment. Doing this would cause a fire when the LiPo battery is installed in the compartment! Install the screws withthe domed head insidethe compartment, and the threaded part, and nut, on the outside ofthe frame.



### 11

# . -. 

# Step #2: Arm Assembly The milled aluminium arms are the nextthing to assemble. The outer arms are supplied with thethrust bearing (the hinge parts) pre-assembled. NOTE: Itis highlyrecommended to avoid disassembling the bearing, since springs and ball-bearings have a habit oflaunching themselves across the room. NOTE: To prevent wearing out the thrust bearing and to avoid 'squeaky'noises when folding the arms itis recommended to puta tinybit ofsilicone grease on the ball bearings so that theyare lubricated and will not wearout the plasticparts. The use ofanyothergrease is not recommended as it often is acidic and will degrade the plastic over time. Assembly ofthe 'center spider' tothe outer arms is simple, install thethrust bearing part into the center spider, add the red washer, install the M4 domed-head screw, and the nyloc nut. NOTE: An additionalsmall thin, white, M4 washeris included in the kit. This must be installed between the head ofthe M4 domed-headscrew, and the red washer. The washerprevents the continuous rotation ofthe arms from unscrewing the screw.



### 12To assemble the arm locking lever, simply insert the spring into the hole in the outer arm, and press the lever into place (a fair amount offorce is needed, don't worry, they don't break easily).



### 13 

# ..Once the arms are complete, they can be attached tothe central electronics plate (Power Distribution Board) using the supplied M4 countersunk screws, and matching nyloc nuts.

Ensure that the swept-back arms (the front arms) are towards the front ofthe plate.



### 14

# Step #3: ESC Mounting ESCs are mounted underthe center section ofthe arms (the 'center spider) using a high-bond double-sided tape. 

### NOTE: Nylon ties, velcro straps, etc. cannotbe used to mount the ESCs due to the fact that the outersection ofthe arm folds overthe innersection. A heat-shrinktube maybe used, assuming the tube is thin enough to allowthe arms to fold.

Once the ESCs are mounted, their power cables may be cutto length, and soldered to the power distribution board, using the solder points shown below:

The pads are arranged so that the coaxial power cables ofthe DJI E300 ESCs can be easily soldered (the outer shield ofthe coax cable is cut back and soldered on the negative pad, and the center conductor soldered ontothe positive pad). 

### NOTE: Don'tbe afraid to cut the ESCpowercables as 

### shortas 

### needed, theycan always be extendedifthe ESCs are to be transferred to anotherplatform in the future.



### 15 

# ... i 

# Step #4: Motor Mounting The outer frame arms are designed for standard 2212-sized, 920kv brushless motors. For motors which use self-tightening props (highly recommended), it is importantto ensure that the two clockwise, and two counter-clockwise motors are installed in the correct locations.



### 16Three motors have been selected bythe lmmersionRC team, and flown successfully for many hours. 1) The motorfrom the OJI E300 motor/ESC set. This motor is easy to install using the screws supplied in the E300 kit. 

### Cables do need extending with these motors 

### eitherby soldering extension wires, orusing the suppliedextension cables. 2) The Tiger AirGear 350 motor/ESC set. Notethat some ofthese motors ship with a prop-shaft circlip which has long 'teeth' which can foul on the center hole ofthe arm. To fixthis, either changethe circlips for a style without these teeth, or use a drill press to makethe hole in the outer arm slightly larger. 

### Cables do needextending with these motors 

### eitherbysoldering extension wires, or using the supplied extension cables. 3) The custom Tiger AirGear 350 set supplied by lmmersionRC. These already have the correct circlip installed, and the correct cable length forthe XuGong 

### (available shortly from XuGong rese//ers). Once the motor is installed, and cable extenders (if needed) are attached, it is a good idea to 'braid' the cables, for cosmetic, and functional reasons. Since 95% ofour demographics are male, plaiting skills are probably limited. A quick google search will explain the technique. Alternatively, askthe wife/girlfriend/motherfor help at this point:-) Last thing to note, ensure thatthe cables arethe correct side ofthe arms to allow folding. This means in front ofthe front arms, and behind the rear arms.



### NOTE: As a/ways 

### when mounting brushless motors, 

### ensure that the screws 

### usedare not too long, andcannot damage the internal windings ofthe motor.

# ..

# Step #5: Electronics Installation Once the frame, and arm/power board assemblies are complete, the next step is to start installing the electronics. The basic idea is thefollowing: 1) Everything gets connected to the power board, including the flight controller, video tx (but excluding the cameras) 2) The Naza GPS cable is inserted intothe supplied pick-off cable, which is then in turn connected to the GPS input ofthe Naza lite (orthe GPS input ofthe Naza PMUv2 on a Naza v2). The 5-pin picoblade connector is then hooked to point 6, shown below. 3) The flight controller is dropped through the hole in thetop oftheframe, and secured (using double-sided foam tape and/or nylon ties) tothe base oftheframe. For recent flight controllers with a seperate BEG, this is installed alongsidethe flight controller. Note that in order for the cables in the rear ofthe Naza to clear the batterybulkheact ensure that the Naza is mountedas far forwards as it can go (clearing the ESC cables of course). You may wish to connect as many ofthe flight controller cables as possible before securing it into the frame, as once in place, attaching the cables can be quite fiddly.



### 18Once all cables are connected, the power distribution board may be secured to the top frame plate using the supplied red silicone dampers (Yes, this is a little tricky, but you are almost done!) The recommended location ofthe Vtx is behind the front left supporting plate, with the antenna exiting through the supplied hole in thefront bulkhead. Why the leftplateyou ask
... because ifthe antenna unscrews in flight foranyreason the antenna 

### will drop behind the gimbal, andnotinto the front-leftprop.



### 19 

# ..Instead of pointing the antenna tothe top, you might consider pointing it down, clearing so the obstruction created by the other elements when in flight. In this case you might rather consider a straight Spironet antenna, bending it down.

# Step #6: Flight Control and UHF Configuration

· DJI Naza Configuration

The Naza should be configured following the instructions provided by DJI, and their configuration tool. For XuGong compatibility, ensure the following is configured: 1) PPM input mode (all channels down a single PPM cable) 2) Camera gimbal disabled (the XuGong gimbal is independent ofthe Flight Controller)

# Step #7: Cleanup, and 

# Fly Before flying forthe firsttime, take sometimetotidy up the wiring, secure 'flapping' cables with nylon ties, and ensure that the cables tothe gimbal/gopro are freeto followthe movement ofthetwo gimbal axes. To prevent damageto the power distribution board in a serious crash, inserttwo (or more) of the security locks through the silicone dampers, and lockthem underneath. These unique locks allow the power board to 'float' above theframe, eliminating vibration, but providing support in a crash.



# Step #8: Tune To tune the current sensor, for precise flight-time estimates, start with a fully-charged battery pack and notethe mAh consumed value from the OSD during the first flight. Then chargethe pack, and notethe number of mAh used to recharge. It will tunethe current sensor to perfection. Attach the power distribution board to a PC using a USB cable, and startthe latest lmmersionRC tools version (download link here). Select the 

### Sensor Diagnostics and Calibration for End Users button and follow the steps to calibrate the voltage, and current sensors.

# The 2-axis Gimbal (Optional) The gimbal is a G3 2-Axis Gimbal from Feiyu-Tech. It has two different modes as described below. 

### Rocker Speed Mode the receiver output control the speed in °/S at which the camera tilts.The neutral value correspond to

# oo/s;maximum value correspond to 15° /s;the minimum value correspond to -15°/S. 

### Rocker Position Mode The receiver output controls the position ofthe camera. The neutral value ofthe receiver output correspond to the horizontal position ofthe Gimbal; maximum value correspond to the maxtilt angle; the minimum value correspond to the min tilt angle.
the only way to change modes is by flashing the corresponding firmware. The default firmware loaded in it is Rocker Speed Modev2.12. We suggest you to upgrade to 2.13 since it fixes some issues with the imu: "Improved the attitude stability ofthe IMU module when under the condition ofvibration andoverload.

# Miscellaneous A few notes supplied by some ofourtest pilots. The kind ofthings that a XuGong pilot needs to know: 1) The flight time estimate is based upon an 80% battery drain value, and not a full drain. Ifyou are getting 20 minute flight time estimates, then unless you are running some pretty poor LiPos, the estimates are reasonable. 2) For long flight times, avoid high 'C' rating packs. The new generation of 1OC packs are lighterthan typical packs, and are quite capable of powering the XuGong (SAh 

### * 10 = SOA, typical hover current is about 12-13A). 3) Common sense, buttryto avoid the use ofvery high power A/V Transmitters with antennas mounted close to the brushless gimbal. A 5.8GHz 600mW Tx, with a SpiroNET Omni mounted in the suggested location is just fine, but a 1W 1.3GHzTx, mounted in the same location will almost definitely upsetthe sensitive IMU on the gimbal. 4) For longer range flying, use a full dipole on the EzUHF receiver, and not a 'sander style' whip. The full dipole will give you, in practice, a 1OdB improvement in range. Use a flexible cable forthe ground-plane half ofthe antenna (galvanized bike brake cable works fine), and let it simply bend when the quad is on the ground. 5) Keep the Naza GPS high above the quad, either using the supplied carbon-fibre rod, or an equivalent length foldable design. Mounting ittoo close to the electronics on the quad will definitely result in poor flight performance. 6) Before each flight, take great care to ensure that the four arm locking levers are firmly locked into place. An arm which folds in flight will result in instant unhappiness. Similarly after a crash (or unexpected 'hard landing'), checkthatthe levers are undamaged. A set offour replacements are shipped with the product, and spares are available from our network of resellers. 7) Before each flight, ensure thatthe arm hinges are tight. Ifarms are routinely loosening over time, apply a drop ofthreadlockto the M4 mounting screw. 8) The switch between theflight cam, and GoPro, is manual, controlled from a channel on the R/C remote. Ifthe selected camera input appears to be non-functional (GoPro shutting down in flight for example), the other camera will be selected automatically.



### 369) The selection of PAL/NTSC is automatic, even when the flight cam, and GoPro are using different standards. It is, however, recommended to configure the flight cam and the gopro to use the same video standard. 10) The component-side ofthe Power Distribution Board is coated with a conformal coating, to reduce the effects of dirt and moisture.
