This ST-38 wheel handle combo from Futaba supplies an RC-scale replacement option for the Futaba T3PJ wheel, with three distinct colours to simplify setup recognition.
The kit contains red, green and blue wheel handles that act as direct spares for the transmitter wheel, useful for replacing a degraded grip or assigning a colour to a specific configuration. These components are designed as plug-in replacements for the wheel assembly on compatible Futaba T3PJ transmitters, allowing swaps without affecting internal electronics.
Use in practice and setup: swapping handles supports consistent steering input by returning a familiar grip after wear, and colour coding speeds up configuration checks at the track. Confirm compatibility with your T3PJ wheel hub before completing installation.
