Replace a damaged or unstable throttle/brake trigger on a compatible FLYSKY Noble transmitter with the correct model-specific replacement. The trigger assembly controls throttle and brake input, so choosing the exact transmitter version is essential before installation. Key Features 🧩Replacement throttle/brake trigger module for repairing a damaged trigger assembly. 🎛️Helps restore stable throttle and brake input when the original trigger or its potentiometer is damaged. 🔀Three model-specific Style options for the NB4/NB4 Pro, NB4+, and NB4 Pro+ families. 📈Useful for abnormal throttle output, including neutral-position fluctuation, inaccurate response, or a trigger that no longer operates normally. 🛠️Internal transmitter repair part, not a complete radio transmitter or a universal trigger component. Model-Specific Compatibility Choose the Style that exactly matches your transmitter. These components are not interchangeable across all Noble models. NB4 & NB4 Pro Throttle/Brake Trigger Compatible with: FLYSKY Noble NB4 and NB4 Pro Noble Plus NB4+ Throttle/Brake Trigger Compatible with: FLYSKY Noble NB4+ only; uses the NB4+ FPC cable arrangement. FLYSKY Noble NB4 Pro+ Throttle/Brake Trigger Compatible with: FLYSKY Noble NB4 Pro+ only; uses the NB4 Pro+ FPC cable arrangement. Critical compatibility warning: Do not install the NB4+ throttle/brake trigger component on an NB4 Pro+ transmitter. The NB4 Pro+ cannot use the NB4+ trigger component, and using the wrong component can cause calibration failure. When Should the Trigger Be Replaced? Inspect the trigger assembly when the throttle or brake trigger is physically broken, the throttle channel does not respond normally, the neutral-position value fluctuates, the endpoint is inaccurate, or the output cannot be calibrated. A fluctuation of more than 2% at neutral may indicate a damaged potentiometer, but also inspect the connector, FPC cable, and related electronics before replacing the trigger. Installation Notes Power off the transmitter and remove the battery before opening the housing. Confirm the exact Style and transmitter model before removing the original part. Check the connector and FPC cable routing carefully. Do not force a connector or fold the cable sharply. After installation, calibrate the throttle and brake controls and verify neutral position, endpoint response, and stable output. If calibration fails, stop and recheck the model-specific trigger, FPC cable, connector seating, and transmitter compatibility rather than forcing the calibration.
