The LapRF is a personal race timing system for FPV quads using 5.8GHz video feeds. 

The passing of a quad through the start/finish gate is precisely measured using the energy emitted by the 5.8GHz transmitter on the quad.

Custom fully-programmable timing receivers, coupled with ImmersionRC's timing antennas ensure that the performance of this system is on a different level than competing products. Video power levels from 10mW through 600mW supported.

Maximum precision for up to 8 pilots, but also supporting up to 16 pilots with lower resolution.
Ethernet connection to event management software.

Fully integrated with the industry standard LiveTime event management software.
3s-4s LiPo power, or equivalent DC power supply. Includes XT-60 connector.
