Immersion RC LapRF 8-Way Event Timing Preliminary Operator's Manual page 3

Introduction
The LapRF 8-Way Event Timing Edition is the first in a family of race timing systems from
ImmersionRC.
LapRF technology uses the emitted 5.8GHz RF from race quadcopters (or fixed wing aircraft) to
detect a passage through the start-finish gate.
Different from other offerings on the market, the LapRF uses custom timing receivers with specially
designed antennas to ensure that only quads which pass through the 'beam' are timed, and other
sources of interference are ignored.
All that is required to use the LapRF in a race is to program the band, and channel that each pilot will
use, place the timer in the start/finish gate, and go fly! ​ N o transponders required​ .
Base Manual
The LapRF 8-Way shares many features with the LapRF Personal Edition, and therefore the manual
for the Personal Edition forms the base of the 8-way manual.
This manual covers the additional features for the 8-way.
