Channels Configuration

Single-channel simplicity delivers pure control right out of the box—In the Channel Configuration menu you can adjust all parameters for your single throttle channel:

• Failsafe: Output position if signal is lost

• Expo: Exponential curve for finer low-end response

• Reverse: Invert servo direction

• Endpoints: Minimum and maximum travel limits

All changes are saved per model, ensuring your throttle behaves exactly as configured on every flight.

Failsafe Setup

The Failsafe function defines a safe preset for your model’s throttle if signal transmission is lost. This is crucial because an unexpected loss of control can cause accidents or damage if the model doesn’t know how to react. For electric setups, configuring Failsafe to cut the motor prevents battery drain and avoids landing with a dead pack.

Why it’s important

• Prevents the model from continuing uncontrolled in flight

• Places throttle control into a safe position

• Protects both your aircraft and bystanders in emergencies

How to set Failsafe

In the Model Setup menu, select Channels, then Failsafe using ↑ and ↓ (it will display NOT SET if not yet configured).

Position the throttle trigger to the desired failsafe positions and press the cursor click to record these positions.

When the confirmation dialog appears use ← and → to choose No (cancel) or Yes (apply).

After confirmation the status will update to ACTIVATED, indicating Failsafe has been saved successfully.

Expo Configuration

The Expo function applies to the throttle channel, shaping the trigger’s response curve. As you move the trigger from idle (fully released) to maximum pull, Expo adjusts sensitivity at each end of travel.

A positive Expo softens throttle response around idle—giving finer low-end control—and makes it sharper near full throttle. A negative Expo does the opposite, increasing sensitivity at low throttle and softening it at the top end. When set to 0, throttle response is purely linear.

To setup Expo setting go into the Model Setup menu, select Channels, then Expo using ↑ and ↓. Then select CH1 option using ↑ and ↓.

Use ↑ and ↓ again to increase or decrease the Expo value.

Once the value is set, press the cursor click to save it.

Reverse Settings

The Reverse function flips the servo’s output axis relative to your control input. With Reverse ON, pushing the control in one direction makes the servo move in the exact opposite direction. This is especially useful if your carburetor servo reacts inversely to your trigger movement.

Reverse the throttle channel does not invert motor rotation. Instead, it makes the idle position (trigger released) register as full throttle (100%), which can cause the motor to spin up unexpectedly and pose a serious safety hazard. Do not enable Reverse on the throttle channel for electric setups.

To setup Reverse setting go into the Model Setup menu, select Channels, then Reverse using ↑ and ↓.

Next, navigate to the CH1 using ↑ and ↓. Once highlighted, press the cursor click to select it.

Use ↑ and ↓ to toggle the Reverse setting between ON and OFF. Once the value is set, press the cursor click to save it.

Endpoints Configuration

Endpoints let you digitally define servo’s travel limits for throttle channel, supplementing any mechanical adjustments. By setting minimum and maximum endpoints, you ensure the servo never exceeds its safe range—preventing binding and fine-tuning control throw. Adjusting endpoints per model guarantees consistent, precise movements every flight.

To prevent binding, disconnect the pushrods before setting endpoints; once you’ve selected the desired values, reconnect the pushrods and make any fine-tune adjustments if required.

To setup Endpoints setting go into the Model Setup menu, select Channels, then Endpoints using ↑ and ↓.

Next, navigate to the throttle channel using ↑ and ↓. Once highlighted, press the cursor click to select it.

To select the endpoint you want to adjust use the use ← and → to choose between minimum or maximum.

Use ↑ and ↓ to increase or derease the endpoint value.

Then press the cursor click to save the values of the channel endpoints.

If you are setting the minimum value and see no change in the servo, then set the maximum value. When Reverse is enabled, the minimum and maximum endpoint values are automatically swapped.
