• Heading-Hold SMM: 21st Century gyro technology. Computer chip technology. Expensive, easier set up, higher durability.
Significant decrease in temperature sensitivity. Many include frame rate settings to allow faster response when using
specialized digital servos. Examples:
• GY401
: Simpler set up. Ideal for learning aerobatics through 3D.
• GY502
: Better centering than 401 for more advanced aerobatics. Ideal through Class III competition.
• GY601
: Exceptional center. Extremely fast response time. Requires specialized servo.
Gyro mixing function is use for adjusting the gain of the gyro and selecting the gain from two different gain settings by switch
on the transmitter with the gyro that can set two different gains witch placed on the model.
To set the GYRO mixing:
1. Plug the gyro’s sensitivity adjustment to channel 5 of the receiver. (not assignable)
2. EPA of channel 5 (see page 12-13) to set 100% both UP and DOWN.
3. Enter the programming mode and use the MODE key to access the
“GYRO”
function.
4. Push the DATA INPUT lever upward. This will cause the flashing
“INH”
display to change to
a flashing
“ON”
display. Now the mixing is on.
5. Push the SELECT key once. This will show the gyro gain setting and flashing “%” symbol on
the display.
Flip the gyro (CH5) switch up and down. This will cause the arrow points up and down on the display simultaneously with
switching operation and show the position of the switch. Push up or down DATA INPUT lever to set the gyro gains both switch
up and down position. Gyro gain can be adjust from -100% to +100%.
