Description
The SkyRC LapWiz combo set is an IR lap timing system for RC car practice and club racing. The decoder detects laps by infrared without buried loop wires and sends the times via Bluetooth to the SkyRC app on a smartphone.
The T04 transponder in this set has a built-in battery and needs no connection to the receiver. The decoder also works with the LapWiz T01, T02 and T03 transponders.
Notes
- Also required: smartphone with iOS or Android and the SkyRC app.
- The T04 charges via a USB-C cable from a 5 V USB power source.
- Each car in a session needs its own transponder ID (01–99). The factory ID matches the last two digits of the serial number on the case.
- Place the decoder on the inside of a straight, perpendicular to the track, with the receiver window level or tilted slightly downward and not facing the sun.
- The IR emitters of the transponder must face the decoder unobstructed, not covered by the body shell or other components.
- The ranges were measured indoors. Lighting, infrared interference, transponder placement and vehicle speed affect detection. Use the sun visor outdoors.
- Set the minimum valid lap time in the app slightly below the fastest expected lap: shorter laps are ignored.
Highlights
- Shadow Run against the personal best lap with real-time delta
- Standalone Mode via Bluetooth without internet, Cloud Mode for backup and sharing
- Up to 99 cars at the same time, racers join a race by QR code
- Multilingual voice announcements, live display on TV via AirPlay or Android casting
- T04 with dual IR emitters, motion sensor and IR power adjustable in the app
- Magnetic sun visor for stable IR detection outdoors
