Docket	ID	FAA-2015-3075

Grussendorf	Nursery INC/	DronezWork LLC is seeking	exemption	to	operate	

Unmanned	Aircraft	Systems	for	the	purpose	of	aerial	image	for	real	estate,	special	

events,	golf	courses,	weddings	and	landscaping	in	areas	within	the	United	States.	

 DronezWork LLC will be providing clients with the knowledge of such equipment 

while submitting them with aerial photographs of there property to use for there 

industry as they see fit. I currently have a landscaping business and the option to 

photograph landscaping jobs would be a useful asset to both the myself and the clients. 

The use of this UAV for public interest is to enhance the usability for such 

projects. It is a proven tool to use for real estate and matters alike. The use of this tool 

for real estate is to give potential buyers a prospective on the property that goes above 

and beyond ground level. The safety of using a small uav is far less risk then flying a 

manned aircraft. If granted the exemption all rules will be followed as described by the 

grantor. Using a UAV is low risk being its has no flammable fuel source, small enough to 

control in close proximity and overall I will be able to provide a service that will be 

affordable and different from all other companies. I would also be able to provide more 

jobs in this field for those looking for part time to full time work. 

I seek relief for exemption as follows.

 

							14	CFR	part	21	sub	H,	91.203	a	and	b,	45.203,	91.405	(a),	91.407	(A)(1),

Equipment	

Yuneec	Q500	Typhoon

Payload	is	cgo2	high	definition	camera	

I	am	seeking	this	exemption	for	the	Yuneec	Q500	series	Unmanned	System.	The	

Q500	has	a	vertical	take	off	controlled	by inputs	by	the	operator.	It	is	efficient	in	
small	maneuvers	with	an	extremely	reliable	“return	to	home”	function.	The	Q500	is	

guided	by	satellite	GPS	and	holds	position	within	+- 3	inches.	The	Q500	has	a	max	

ground	speed	of	no	more	then	15	MPH	and	a	take	off	speed	of	no	more	then	10	MPH.	

The	Q500	has	a	battery	run	time	of	up	to	25	min	and	auto	land	is	battery	exceeds	

low	voltage.	The	Q500	has	4	main	electric	motors	with	warning	lights	on	the	ends.	I	

have	the	Q500	registered	with	the	Yuneec	California	Company.	

Ground	Station

ST10+

The	ground	station	to	operate	the	Q500	Has	3	levels	of	flight.	

1) Safety	mode

2) Angle	Mode

3) Return	to	home	mode

These	are	setting	used	by	the	operator	depending	on	there	level	of	

confidence,	experience	and	project	goals.	

The	controller	has	a	max	range	of	2000’	distance	and	1000’	altitude,	which	

can	be	configured	and	locked	to	meet	FAA	guidelines.		The	controller	also	

utilizes	a	5.5”	Screen	with	a	5.8	grtz	down	link	so	the	image	can	be	scene	

directly	at	the	operator’s	hands.	In	case of	“Loss	Of	Link”	the	Q500	with	

automatically	return	back	to	home	position	until	connection	is	reestablished.	

GPS

The	Q500 utilizes	multiple	satellites	to	pinpoint	its	location	and	maintain	

altitude	and	drift.	Along	with	the	GPS	that	is	in	the	ground	station	and	the	

GPS	in	the	Q500	this	is	the	most	reliable	connection	in	any	unmanned	

aircraft.	

Return	to	Home

In	at	any	point	if	the	operator	feels	that	there	is	a	safety	issue	with	either	his	

equipment,	himself	of	others	they	have	the	option	the	hit	the	“return	to	

home”	function	and	the	Q500	will	ascend	to	60’	and	begin	to	fly	back	to	the	

operator.	When	the	Q500	has	reached	10’	of	the	operator	it	will	begin	a	slow	

decent	at	approx.	3	MPH,	land	and	shut	down.	At	any	point	when	the	return	

to	home	function	is	activated	the	operator	to	take	control	and	maneuver	as	

they	see	fit.		

Line	of	site	Flying		

With	the	work	that	will	be	done	using	unmanned	aircraft	will	have	no	reason	

to	be	leave	that	flying	out	of	the	line	of	site	will	be	a	concern.	Keeping	a	close	

visual	of	the	Q500	is	important	with	the	performed	task.	
Q500	powered	source

The	Yuneec	Q500	is	powered	by	a	5400	mAh Lithium	Polymer	battery	with	a	

run	time	of	approx.	25	min.		

Vertical	Take	off/	landing	

The	Q500	Has	a	vertical	take	off	along	with	a	vertical	landing.	

Maintenance

Q500	will	maintain	daily	inspections	along	with	inspections	log.	Daily	flight	

log	will	also	be	reordered					

The	propose	of	seeking	relief	for	this	exemption	is	in	such	cases	the	

photograph	methods	I	am	perusing	by	using	unmanned	Aircraft	is	a	safe	

alternative	then	using	manned	aircraft.	The	operator	will	only	fly	for	a	

deration	of	25	min	at	a	celling	of	400’	or	less,	within	the	line	of	site,	and	will	

terminate	the	flight	if	safety	to	others	is	a	factor.	The	aircraft	will	be	under	the	

regulation	55lb	weight	limit	and	at	no	time	will	exceed	that.
