In Ver 3.9 or later software with the model ID function added, model data saved on the SD card cannot be called using the model
select function. To use the model data of the SD card, copy the model data to the transmitter.
If the model data of the SD card was selected before the update, an error message will be displayed at the first startup after the
update, and the model will automatically switch to the model data of the transmitter.
1. Add Model ID FASSTest, T-FHSS
As an added level of safety in the form of Model ID, which will prevent the accidental control of a model
when using a different model data by preventing link.
1. Add O.S.ENGINE EM-100 Telemetry function FASSTest, T-FHSS
Supports EM-100 firmware version Ver.8.00 or later.
1. Fixed defect
Fixed a problem that telemetry reception time.
T18SZ SOFTWARE UPDATE CHANGES
This software updates or alters the functions and features noted below. The instructions and information that follow are meant as a
supplement to the original instruction manual that accompanied the transmitter. Please refer to the original instruction manual where
applicable, but replace the steps indicated below with these instructions. Please check to ensure that the update has been installed.
1) Select the System Menu.
2) Touch the [Information] button.
3) Confirm that the information in the display indicates the version numbers as noted above.

Important: When you update your radio to V3.9 and add the Model ID function, you
must re-link existing FASSTest or T-FHSS receivers in your current models.

2. Improved model copy function
Conventionally, only the model data currently active can be copied. In version 3.9, you can copy any
model data.
■ In the system types (FASSTest, T-FHSS) compatible with
the model ID function, a unique ID number (model ID) is
set to each model data. Linking with a receiver stores the
model ID of the model data in that receiver. The receiver
operates only when it receives radio waves transmitted
using model data that matches the stored model ID. As a
result, the receiver does not operate even if model data of
an unintended setting is used by mistake, so it is possible
to prevent a malfunction due to a model selection mistake.
When using R3004SB
■When using the R3004SB, set “Receiver” in the system type screen T-FHSS mode setting to
[R3004SB]. When using other T-FHSS compatible receivers, set "Receiver" to [Normal].
■ If you want to use different model data from the model
data that you have been using, link again.
■ Model ID feature is enabled only if the system type is
FASSTest or T-FHSS. Please note that model ID function
can not be used on other systems.
■ For safety reasons, model ID function can not be disabled.
■ Model ID is automatically set when copying or adding
model data.
R3004SB receiver does not support model ID function.
Change to "R3004SB"
Link is required when a new model is made from a model selection.

INT (integration) Timer is the function which changes progress of a timer according to the location of the throttle
stick. When the throttle stick is raised for faster speed, the speed of the timer usually increases. With the throttle
stick at mid-range speed, the timer speed decreases (to 50%). When the throttle is positioned at low end, the
timer's progress stops. It's possible to set it in the time which fits the power consumption of your aircraft.
*The consumption of the battery/fuel is different depending on the conditions, so use an INT Timer as reference.
*The INT (integration) time is different from the actual elapsed time.
