HELI	S900	&	S-800	INFO

Pre-Flight	Instructions

6-3-15

Turn	monitors	and	transmitters	on.	Wait	15	seconds	for	EACH	UNIT	to	

connect!	RC=first;	Lightbridge=second,	Tablet=third;	heli=last.	Pilot	

transmitter:	plug	in	cable	to	back	of	transmitter.	Camera	transmitter:	

turn	on	power	button.	

SWITCH	RADIO(S) TO	SPECIFIC	HELI (S-800	or	S-900)

(Use	scroll	wheel	on	RC	to	select	unit,	press	center	button,	scroll	to	

correct	unit,	push	center	(return)	button;	execute	by	holding	rtn	button	

for	one	second)

Connect	transmitters	via	cable.	

Connect	FPV	CAM	to	batt.	and	remove	lens	cap.	Check	Batt.	level.	

Turn	on	camera...remove	lens	cap...check	battery	level,	check	memory	

card	space.	

Set	up	GH4 EXPOSURE parameters...	

1. Movie	setting 2.	Aperture	priority 3.	F-11	to	f-16 4.	Shutter	to	120

or	above 5. ISO	to	setting	that	produces	correct	shutter	speed 6.	

Exposure	Compensation	as	needed 7.	Press	shutter	1⁄2	way	to	set	

auto focus	(AFC),	or	set	manual	focus.

Check	all	batteries	with	pocket	unit	for	level	and	correct	individual	cell	

voltage.		Raise	Heli	antenna

Connect	battery	to	heli...test	camera	movement	and	do	gimbal	test

Setup	cellphone	for	Flytrex	LIVE

Check	heli	arm	positions	&	motors	for	tightness	and	lock

Blow	out	all	motors	with	canned	air

Check	heli	blades	for	nicks,	cracks,	roughness	and	tightness

Check	heli	motors	for	debris

Hand	spin	heli	blades	to	test	motor	magnets

Check	landing	gear	for	tightness	and	proper	position

Check	gimbal	mounting	for	tightness	and	proper	alignment	on	frame

Check	battery	mounting	for	tightness	and	“																																																“

CHECK	BALANCE	ON	HELI

To	set	COMPASS:	Click	left	switch	7	times

Rotate	heli	360	in	normal	and	then	vertical	position	to	set	compass

Check	for	GPS	acquisition
Check	all	radio	switch	positions:		

1.	GPS	switch	MUST	be in	GPS	mode.		2.	POI	switch	

must	be	in	POI	mode.	POI	mode exhibits	the	green and	

purple flash.		BNK	Mode	allows	the	craft	to	bank	about	30	degrees	

while	turning.

Attitude exhibits	yellow	and	purple flash.		Blue	LED	flash	=	

FAIL	SAFE	MODE.

Check	all	tablets	screen	info	to	check	if	correct	 1.	MUST	have	7	or	

more	satellites	to	fly	safely	in	GPS	mode.

SET	PHONE	TIMER	as	appropriate.	{RTB	AT	21.0 VOLTS}

DO	NOT	GO	BELOW	20V.	

Move	everyone	back	at	least	20	feet

Throttle	heli	up	to	about	eye	level.	Check	controls,	then	RAISE	LANDING	

GEAR

UPON	RETURN	TO	BASE:

LOWER	LANDING	GEAR!!!!

Set	heli	down	softly on	level	surface,	preferably	on	grass

CUT	RECORDING

Unplug	batteries	CHECK	BATTERY	VOLTAGE	AND	MOTOR	

TEMPS!!!

Blow	out	all	motors	with	canned	air	before	EACH		&	EVERY	

LIFTOFF	if	in	dusty	conditions.

RESET	TIMER:	Use	scroll	wheel	to	highlight	T2,	press	rtn inside	of	scroll	

wheel;	scroll	to	“Reset”;	Click	the	“Home/Exit	button	(silver	button	on	

the	left	side	of	the	transmitter	screen)	to	get	back	to	the	home	screen.		

Repeat	for	T1	timer.		(RTN	button	makes	timer	numerals	large.)

Re-balance	Heli	each	time	a	battery	is	replaced

TO	TAKE	A	PICTURE	OR	RECORD	A	VIDEO:

To	record	video,	set	camera	to	Movie	(M).	Flip	the	“Shutter”	toggle	

twice to	start,	and	twice to	stop.

To	take	still	images,	change	GH-4	to	appropriate	still	settings	Aperture	

(A)	(on	the	ground).		Use	“Shutter”	toggle	twice	(as	above).
TO	PAN OR	TILT GIMBAL:	

PILOT RADIO:	Use	sliding	switches	on	side	of	radio.	L.	side	=	PAN.	

R.	side	=	TILT

CAMERA RADIO:	Use	sticks.

Keep	the	“H.Free/Reset/H.	Trace”	switch	in	“H.	Free”	to	have	full	

control	of	camera	movements.	“RESET”	puts	camera	straight	forward	

and	level.

Forward/Down switch	should	be	in	the	Forward	position	to	record	

with	the	camera	looking	straight	ahead.	If	you	want	the	camera	to	look	

down,	put	the	“H.Free/Reset/H.	Trace”	switch	in	the	RESET	mode	and	

then	move	the	Forward/Down	switch	to	Down.	To	move	the	camera	

back	to	the	Forward	looking	position,	put	the	switch	again	in	Reset	and	

move	other	switch	to	Forward.	This	sequence	must	be	done	each	time	to	

move	the	camera	from	a	“forward	looking”	position	to	a	“downward	

looking”	position.

HmLnk will	cause	the	heli	to	fly	as	if	it’s	pointing	nose	away	from	me	no	

matter	what.	So,	if	the	heli	gets	turned	around	(nose	sideways	or	nose	

toward	me)	flip	to	HmLnk and	return	to	home	base	so	that	the	heli	can	

be	re-oriented	(nose	away	from	me).

The	T14SG	Radio	(HELI Control	Unit)	can	be	charged	to 6.5	volts.		5.2

Volts	is too	low	to	keep	operating, and	at	3.9	volts,	it	shuts	

off.			The	GIMBAL	Control	Unit uses AA	batteries	and	should	

always	read	more	than	4.4 volts.

BINDING	THE	S-900	OR	S-800

If	the	Lightbridge	controller (that	has	the	fan) has	2	red	lights	on	it	

instead	of	one	red	and	one	green,	then	the	system	probably	needs	to	be	

bound:

1.	Power	off	Lightbridge	and	heli
2.	Power	up	Lightbridge	and	immediately	power	up	the	heli	and	

immediately	push	a	paper	clip	into	the	side	of	the	unit	on	the	heli	that	

has	the	fan	running.

3.	Push	the	clip	into	the	reset	hole	for	about	5	seconds.	The	two	red	

lights	should	now become	one	green	and	one	red	and	the	gimbal	

controls	should	work	and	the	camera	should	be	able	to	be	seen.	

S-900	SETTINGS	TO	SWITCH	CONTROL	OF	GIMBAL	TO	

PILOT	OR	CAMERA	OPERATOR

To	switch	between	the	pilot	control	of	the	gimbal	and	camera	operator	

control	of	the	gimbal:

Turn	on	both	remotes;	turn	on	both	LightBridge	units/	connect	the	blue	

cable	from	Pilot	RC	to	Operator	RC;	plug	the	USB	cable	from	the	Pilot	RC	

to	the	laptop.	Open	the	LightBridge	program;	go	into	Channels	reset	the	

channels	as	listed	below:
