F Rate (Frame Rate)
Frame rate is the response rate of the receiver. The lower the
number, the faster the response. Frame rate only affects the
current model.
IMPORTANT:
You should always use the fastest response
rate the servos can handle. This gives the lowest latency and
fastest response. If the frame rate is incompatible with the
servo, the servo will move erratically or in some cases not at
all. If this occurs, change the frame rate to the next highest
value.
The available frame rates will depend on the type of receiver the
DX4S is bound to:
DSMR:
11 or 22ms
DSM2:
16.5ms
1. Use the roller to highlight the F Rate function.
2. Press the roller.
3. Rotate the roller to select the frame rate and press the roller
to save the selection.
