Futaba GY611 - Manual (Page 7)

S9256 Usage Precautions
Do not use the S9256 with applications other than the
GY611 gyro.
· The S9256 is designed to be used with the GY611 only, and will not operate
in other applications. Trouble may also occur.
Immediately after flight, do not touch the S9256 case.
·The heat sink section of the case is extremely hot, and may cause burns.
When mounting in the fuselage, install the S9256 so that it
does not touch the servo case and metal parts of the heli-
copter frame.
· The middle case has an aluminum heat sink construction, and will generate
a large amount of noise if touched. In this case, it will become impossible to
receive and is extremely dangerous.
· Current Drain:
The S9256 is designed to be used with the GY611 gyro only, especially to
operate at high speed. Therefore, the servo starts, a correspondingly large
current flows and the current drain is, therefore, large. Constantly pay atten-
tion to the remaining capacity of the Nicd battery and decide the number of
safe flights. Always pay attention to the following points:
· Always use an Nicd battery. A dry cell battery will not display the spspecified
performance.
· When using the S9256 in a system with a battery fail safe function, the cut-
off voltage is set to a high value. Shortening of the flight time due to this
must be included in calculation.
· Install the servo so that it does not get caught on the push rod or does not
loosen even when operated over its full travel. If unreasonable force is ap-
plied, the current drain will increase tremendously and shorten the life of the
servo and accelerate battery consumption.
Always perform proper maintenance for ultimate perfor-
mance.
· The rigidity of the fuselage tail has a large effect on gyro performance.
Make the fuselage vibration as small as possible.
·Fuselage vibration has an adverse affect on gyro operation.
