Model Setup

Model Select

Create, select, add, clone, or delete models.

Edit Model

Edit basic model parameters like name or picture. Resets mixers if type changes.

Flight Modes

Set up switch-selectable tasks or flight behavior. Supports independent trims and mixer variables.

Mixer

Configure model's control functions, combine inputs, map to output channels.

Outputs

Interface for adapting logical outputs to mechanical characteristics. Configure throws, reverse, subtrim.

RF System

Owner Registration ID

8-character ID for receiver registration and Smart Share. Must be same across transmitters.

Internal Module

Overview of TD-ISRM module: 2.4GHz/900MHz paths, ACCESS, ACCST D16, TD MODE.

ACCESS Mode

2.4G/900M paths work together, supporting up to 3 receivers.

Phase One: Registration

Register receiver to radio. Process involves registration and binding.

Reg. ID

Owner/transmitter level ID for Smart Share. Defaults to Owner Registration ID.

Range

Perform range check at field to evaluate reception quality. Reduces transmitter power.

Set Failsafe

Determine receiver action when transmitter signal is lost (Hold, Custom, No Pulses, Receiver).

Adding a Redundant Receiver

Bind a second receiver for redundancy. Connect via SBUS Out to main receiver.

Set – Receiver Options

Access receiver options like Telemetry Power, PWM Speed, Port, Share, Reset Bind.

Model ID

Unique ID for Model Match binding. Sent to receiver during binding.

Bind

Initiate binding process for ACCST D16. Select operation mode (Telemetry/Channels).

Smart Port telemetry

RSSI

Receiver Signal Strength Indicator. Warns of low signal quality.

VFR%

Valid Frame Rate sensor for Link Quality. Can set up alerts via Logical Switches.

Telemetry Settings

Discover new sensors

Enable to discover new sensors after connection and binding. Flashing dot indicates data reception.

Create DIY Sensor

Add a DIY or 3rd party sensor. Configure Name, Value, Unit, Decimals, Range, etc.

Auto Detect

List detected S.Port/F.Port sensors. Select DIY sensor from list. Auto-populates IDs.

Create Calculated Sensor

Add calculated sensors like Consumption, Distance, and Trip.

Consumption Sensor

Calculate energy consumed by motor from current sensor (e.g., FAS series). Configure Name, Unit, Range.

Distance sensor

Calculate distance traveled from GPS sensor. Configure Name, Unit, Range (0-10km).

Trip Sensor

Calculate accumulated distance between GPS coordinates. Configure Name, Unit, Range (0-10km).

Editing and Configuring Sensors

Edit sensor settings: Value, ID, Name, Unit, Decimals, Range, Write Logs.

Programming Tutorials

Initial radio setup example

Initial steps for setting up the radio itself before programming models.

Step 1. Confirm System settings

Step 2. Identify the servos/channels required

Step 3. Create a new model

Step 4. Review and configure the mixes

Throttle Cut

Throttle safety latching mechanism. Prevents unexpected motor start.

Throttle Hold

Cut motor in emergency. Instantly reduces throttle output to -100%.

Step 5. Configure the Outputs

Step 6. Introduction to Flight Modes

Step 7. Add a VFR alert

Step 8. Set up a LiPo battery timer

Step 9. Add a mix for retracts

'How To' section

1. How to set up a low battery voltage warning

Monitor battery voltage with FLVSS sensor, set alert threshold using Logical Switch.

2. How to set up a battery capacity warning using a Neuron ESC

Monitor battery usage (mAh) with Neuron ESC, set warning for consumption or voltage.

3. How to set up a battery capacity warning using a calculated sensor

Use FASxxx current sensor with calculated Consumption sensor for battery monitoring.

6.How to configure a Butterfly mix

Add Butterfly mix for glider braking. Use curve to convert slider range, set aileron/flap response.
