Gyro Initialization, Response Test And Adjustment; Initialization And Response Test - Horizon Hobby E-Flite Blade SR Manuel D'utilisation

8. Advance the throttle stick upward slowly, just until both the main and tail rotor blades begin to spin. DO NOT attempt to fl y the
helicopter at this time. Note the direction the main and tail rotor blades spin. The main rotor blades spin clockwise when viewed from
the top, with the tail rotor blade spinning clockwise when viewed from the right-hand side of the helicopter. If the main rotor blades
are operating in the wrong direction, simply reverse the position of any two motor wire lead connections to the 2-in-1 unit.
9. With the tail motor/rotor spinning at a low rpm, check that the tail rotor is responding properly to transmitter inputs. When inputing
a slight amount of right rudder, the tail rotor rpm's should increase, pushing the nose of the helicopter to the right. If you are on
carpet, grass, or an otherwise uneven surface, be very careful not to allow the helicopter to catch the vertical fi n when testing the
tail rotor control on the ground (or during liftoff when beginning a fl ight).
After confi rming that both rotor blades are rotating in the correct directions, and the tail rotor is responding properly to rudder
inputs, your Blade SR is ready for fl ight. However, please be sure to review the following sections of the manual BEFORE proceeding
with the fi rst fl ight.

Gyro Initialization, Response Test and Adjustment

Your Blade SR model is equipped with an E-fl ite G110 Micro Heading
Lock Gyro. This gyro offers an excellent blend of size, weight,
features and performance.

Initialization and Response Test

The following includes the steps to properly initialize and operate the gyro.
1. After connecting the fl ight 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 fl ight battery
from the 2-in-1 unit) and repeat the correct process.
2. Once the gyro initializes properly, confi rm that the gyro is responding properly 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.
3. Secure the helicopter and ensure that all objects are free and clear of the tail rotor blades, 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.
4. 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.
5. After confi rming that the tail motor/rotor responds properly to inputs from the gyro, disconnect the battery from the 2-in-1 control
unit. Power down the transmitter and reconnect the main motor to the 2-in-1 unit.
