Flying the 200 S

Advanced Settings

Consult your local laws and ordinances before choosing a

location to ﬂ y your aircraft.

We recommend ﬂ ying your aircraft outside in calm winds

or inside a large gymnasium. Always avoid ﬂ ying near

houses, trees, wires and buildings. You should also be

careful to avoid ﬂ ying in areas where there are many

people, such as busy parks, schoolyards or soccer ﬁ elds.

It is best to ﬂ y from a smooth ﬂ at surface as this will allow

the model to slide without tipping over. Keep the helicopter

approximately 2 ft (600mm) above the ground. Keep the

tail pointed toward you during initial ﬂ ights to keep the

control orientation consistent. Releasing the stick in Stabil-

ity Mode will allow the helicopter to level itself. Activating

the Panic Recovery button will level the helicopter quickly.

If you become disoriented while in Stability Mode, slowly

lower the throttle stick to land softly.

During initial ﬂ ights, only attempt takeoff, landing and

hovering in one spot.

Takeo

NOTICE: If the main motor or tail motor do not startup

properly when throttle is ﬁ rst applied, immediately return

the throttle to idle and try again. If the problem persists,

disconnect the ﬂ ight battery, check for binding in the

gear train and ensure no wires have become entangled

within the gears.

Place the model onto a ﬂ at, level surface free of obstacles

and walk back 30 feet (10 meters). Slowly increase the

throttle until the model is approximately 2 ft. (600mm)

off the ground and check the trim so the model ﬂ ies as

desired. Once the trim is adjusted, begin ﬂ ying the model.

Hovering

Making small corrections on the transmitter, try to hold

the helicopter in one spot. If ﬂ ying in calm winds, the

model should require almost no corrective inputs. After

moving the cyclic stick and returning it to center, the

model should level itself. The model may continue to

move due to inertia. Move the cycle stick in the opposite

direction to stop the movement.

After you become comfortable hovering, you can progress

into ﬂ ying the model to different locations, keeping the tail

pointed towards you at all times. You can also ascend and

descend using the throttle stick. Once you’re comfortable

with these maneuvers, you can attempt ﬂ ying with the tail

in different orientations. It is important to keep in mind

that the ﬂ ight control inputs will rotate with the helicopter,

so always try to picture the control inputs relative to the

nose of the helicopter. For example, forward will always

drop the nose of the helicopter.

Low Voltage Cuto (LVC)

LVC decreases the power to the motors when the battery

voltage gets low. When the motor power decreases and

the red LED on the ESC ﬂ ashes, land the aircraft immedi-

ately and recharge the ﬂ ight battery.

LVC does not prevent the battery from over-discharge

during storage.

NOTICE: Repeated ﬂ ying to LVC will damage the battery.

Landing

To land, slowly decrease the throttle while in a low-level

hover. After landing, disconnect and remove the battery

from the aircraft after use to prevent trickle discharge. Fully

charge your battery before storing it. During storage, make

sure the battery charge does not fall below 3V per cell.

The 200 S default settings are appropriate for most users.

We recommend ﬂ ying with the default parameters before

making any adjustments.

WARNING: To ensure your safety, always

disconnect the motor wires from the ESC

before performing the following steps. After you have

completed the adjustments, reconnect the motor wires

to the ESC before attempting to ﬂ y the model.

Gain Parameters

1. Cyclic P Gain Adjustment (Default 100%)

Higher gain will result in greater stability. Setting the gain

too high may result in random twitches if your model

has an excessive level of vibration. High frequency

oscillations may also occur if the gain is set too high.

Lower gain will result in less stability. Too low of a value

may result in a less stable model, particularly outdoors

in winds.

If you are located at a higher altitude or in a warmer

climate, higher gains may be beneﬁ cial—the opposite

is true for lower altitude or colder climates.

2. Cyclic I Gain Adjustment (Default 100%)

Higher gain will result in the model remaining still, but

may cause low frequency oscillations if increased too far.

Lower gain will result in the model drifting slowly.

If you are located at a higher altitude or in a warmer

climate, higher gains may be beneﬁ cial—the opposite

is true for lower altitude or colder climates.

3. Cyclic D Gain Adjustment (Default 100%)

Higher gain will improve the response rate of your inputs.

If the gain is raised too much, high frequency oscillations

may occur.

Lower gain will slow down the response to inputs.
