STARTING

1. Before every start, Check

if the filter is clogged.

Check muffler bolt.(Fig.1)

2. Power on. Make sure the

screen displays ‘IDLE’ and

the LED on H2 is ‘solid

green’(Fig.2). If not,

please see Trouble

Shooting chapter.

3. Pull the starter quickly

until the engine start

(Fig.3)

4. If the engine does NOT

start after 5 times of pull,

please check the fuel

supply and dry spark plug

(see trouble shooting).

5. Operate engine for a few

minutes for the warming

up. The battery will be

charged automatically.

6. Make sure the LED is

“solid green”. Monitor

the screen (Fig4). If ‘IDLE’

or ‘RUN’ displayed, it’s

ready for takeoff. If

‘CHARGE’ displayed,

please wait a few minutes

for batteries charging

until ‘IDLE’

NOTES: Removing muffler

or gasket lead to derated

power. Check muffler bolts

before use.

H2 can share running status and errors information with Flight

Controller via #5 wire. The transmission protocol is TTL and

CAN (CAN is available later) Please require protocol from us.

STOP

1. Be sure to have H2 cool down for 30 seconds after flight.

2. Switch OFF. H2 will stop in 3 seconds.

NOTES

● H2 has “EMERGERNCY STOP” bottom.

● Correct maintenance is necessary to keep H2 high

performance

● H2 controller lamp blinks ‘green and red’ for 4 hours.

H2 is reaching the maintenance cycle (75 hours). H2 is

still able to start . Please follow the MAINTENANCE in

separate manual.

● If H2 is NOT maintained at every 75 hours cycle, it will

lead to performance degradation.

● The controller lamp stops blinking ‘green and red’ 2

hours after every 75 hours cycle.

RUN

1. Make sure the LED is ’solid green’, and monitoring the

UAV input voltage.

2.

3. Take-off

4. Voltage may drop 2~3 V when encounters air turbulence

or sudden maneuver.

Please pay

attention. Land and inspect when necessary.

Important

● H2 has 1800mah (79.92Wh) LiPo Battery with capacity of

90-secend emergency landing. Bigger capacity, eg.

5000mah (222Wh), can provide about 3 minutes for

emergency landing or return to home.

“EMERGENCY STOP”

Voltage should be at 49 ± 1V

If the voltage drop rapidly to under 45 V
