Sensor kit propeller positioning
• This upgrade allows all current YGE ESCs to be equipped with propeller positioning (except 35LVT and Optos).
• The package includes the sensor, magnets, an adapter board, and all necessary connection cables.
• Sensor cable length: 40cm
• The YGE Sensor Kit propeller positioning does not work with the following ESCs: - YGE 35LVT - Propeller positioning works after updating to the latest firmware - YGE Opto 135 - YGE Opto 255
USB Adapter
• PC interface for updating and programming all current and future telemetry controllers
• Advanced settings for the telemetry protocol, BEC voltage, and motor-specific parameters such as timing and start-up behavior
• Log data (min/max values) of the last flight can be read
• Associated configuration and update tool is available for download
TexY
TexY extends the telemetry capabilities of our new generation of ESCs (T-Series) to include four additional manufacturer protocols: • Futaba SBUS2, • FrSky S.Port, • Spektrum XBUS, • Powerbox Core • Setup is plug-and-play with auto-detect! • Operating status is indicated by four colored LEDs • Dimensions: 39 x 12 x 9 mm • Weight: approx. 3 g
Caps 5
This electrolytic capacitor module is a very useful upgrade for our controllers up to 8s LiPo batteries. It enables maximum partial load stability and optimal performance at the limits. It also compensates for line inductance when using extended cables.
Caps 7
This electrolytic capacitor module is a very useful upgrade for our controllers for up to 15s LiPo batteries. It enables maximum partial load stability and optimal performance at the limits. It also compensates for line inductance when using extended cables.
Caps 9
This electrolytic capacitor module is a very useful upgrade for our controllers for up to 15s LiPo batteries. It enables maximum partial load stability and optimal performance at the limits. It also compensates for line inductance when using extended cables.
VBAR Adapter Cable (Vstabi-Adapter)
• Adapter cable for using an LVT/HVT controller with Vstabi telemetry
• Connection of the RPM output for use with the Vstabi governor
• Alternatively, a one-piece cable is supplied for all Aureus, Saphir, and 205HVT controllers.
