4. Trims Initial Set-Up
- Steering trim (DT1) check
On the initial set-up, steering trim is assigned to the DT1 trim le-
ver above the steering wheel. Operate the lever and make sure the
marker moves on the ST graph. If default has been changed, test
steering trim in its new location. After checking the trim, set the
trim display to the center (N) position.

2. Servo Response Mode Check
When the RX type is set to S-FHSS 2.4GHz (SFH), the servo response mode can be
set to the high speed mode (HIGH). However, check if the servos used are compatible.
When using digital servos (including BLS Series
brushless servos), either HIGH or NORM" can
be used. Since HIGH cannot be used with other
analog servos, the servo response mode must be
set to NORM . If the setting is incorrect, change
it using RX MODE (P42). When the RX type is
set to FHSS 2.4GHz (FH) the high speed mode
cannot be selected
On the initial set-up, throttle trim is assigned to the DT2 trim lever
on the left side of the steering wheel. Operate the lever and make
sure the marker moves on the TH graph. If the default has been
changed, test the throttle trim in its new location. After checking
the trim, set the trim display to the center (N) position.
3. Throttle Mode Check
The throttle servo travel can be set to 5:5 or 7:3 for throttle trigger
operation as required by the throttle mode function (page 78).
