Initialization and Response Test

The following checklist includes the steps to properly initialize and operate the gyro.
• After connecting the flight battery to the 2-in-1 unit, do not move or sway the helicopter. Allow it to remain motionless
until the red LED on the gyro illuminates solidly, indicating that the gyro has initialized properly and is ready for use.
Note: It is extremely important that you do not move or sway the helicopter after powering it on and before the gyro
initializes. The gyro must be allowed adequate time to record the neutral position in order to initialize for proper
operation. If you ever accidentally move the helicopter after powering it on and before the gyro initializes, power
the helicopter off (by disconnecting the flight battery from the 2-in-1 unit) and repeat the correct process.
• Once the gyro initializes properly, and before making your first flight, confirm that the gyro is responding properly to the
movements of the helicopter and providing proper inputs to the tail rotor in order to counteract any unwanted changes in
yaw.
For added safety during the test, disconnect the main motor from the 2-in-1 control unit.
• Then secure the helicopter and ensure that all objects are free and clear of the tail rotor blades Reconfirming that the
main motor has been disconnected from the 2-in-1 control unit, advance the throttle/collective stick on the transmitter
to approximately 1/4–1/2 travel. Use caution, as the tail motor may begin to spin the tail rotor blade.
• Now it is necessary to confirm that the tail motor/rotor responds properly to inputs from the gyro. While holding the
helicopter securely and ensuring that all objects are free and clear from the tail motor, quickly twist the nose of the
helicopter to the left. If the tail motor/rotor is responding properly to inputs from the gyro, the rpm's will increase to
counteract the nose twisting to the left, in order to bring the nose back to the right. When quickly twisting the nose of the
helicopter to right, the rpm's should decrease or stop entirely. If the tail motor/rotor is not responding properly, use the
reverse switch located on the gyro to reverse the direction of response.
• After confirming that the tail motor/rotor responds properly to inputs from the gyro, disconnect the
battery from the 2-in-1 control unit. Then, power down the transmitter and reconnect the main motor to
the 2-in-1 unit.
Now that you've confirmed the gyro provides proper inputs to the tail motor/rotor, review the following sections of the
manual BEFORE proceeding with the first flight.

Gain Adjustments

The G110 offers optional-use remote mode selection and gain adjustment features. These features allow the gyro mode
(Standard Rate or Heading Lock) and gain values to be set remotely in the transmitter. However, for simplified use, while
maintaining maximum performance in the Blade SR, these features will not be utilized (they are usually best utilized when
using a programmable computer transmitter).
• Because you will not be utilizing the remote mode selection and gain adjustment features of the gyro, the gyro's
yellow-colored auxiliary (AUX) lead and connector will not be plugged into the receiver. This is not a problem as the gyro
will always be in the heading lock mode and the gain value can be set using the gain value adjustment pot located on the
gyro itself.
• After making the initial test flight, you may find that it is necessary to adjust the gyro gain setting value prior to
subsequent test flights in order to achieve the best possible performance. The goal, when using a heading lock type
gyro, is to find the highest gain setting value at which the tail/nose of the helicopter does not twitch quickly (oscillate)
from side to side in all areas of flight (including fast forward flight and descents). In the case of the G110 in the Blade
SR, we find that it is typical to have the gain setting adjustment pot set as shown below, which is only a few degrees off
of full counterclockwise.
Optimum Range
• Small, air swooshing noises along with a small amount of movement side to side is normal for a direct-drive tail system,
like that found on the Blade SR. Don't confuse this for a gain setting that is too high.
Note: If the tail spins in one direction or the other as you are trying to lift off, please check the gyro gain. It may be
adjusted too high or too low.

Trim Adjustments

During flight, it may be necessary to make some small adjustments to the rudder trim in order to prevent the nose/tail of
the model from "drifting" to the left or right when the rudder stick is in the neutral position. Typically, only a small amount of
adjustment may be necessary.
Note: It is always best to avoid sudden temperature and environmental condition changes when using a gyro. For
example, it is best to not fly a model on a very hot (or cold) day immediately after removing it from an
air-conditioned (or heated) vehicle. It is also best to keep the gyro out of direct sunlight and away from any
heat-generating sources on the model.
To help the gyro better acclimate to temperature and environmental conditions at the flying field, it is best to let your Blade
SR stand in the environment for approximately 10–15 minutes before flying, allowing the temperature of the gyro sensor to
stabilize. If you do not allow the temperature to stabilize, you may experience radical trim changes that require significant
adjustments of the rudder trim during flight.
