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.
Getting Started The 8-way has been designed to be used by anyone interested in timing an FPV racing event, without special skills. 1) Apply power, and install in the start/finish gate. 2) Hook up the Ethernet cable to either a network, or a direct connection to the timing PC 3) Set an appropriate IP address using the built-in OLED display. a) If used on a network, reserve a static address for the LapRF b) If a direct connection is used, set an address compatible with the static IP address of the timing PC.
Heat, the #1 enemy of electronics FPV races are a lot more pleasant when the snow has melted, and the days are long enough for more packs than your charger can keep up with. These spring and summer months closer to the equator brings the sun, and the potential damage that it can cause to electronics used for FPV racing.
Limitations In general, you will find the LapRF to be truly best-in-class when it comes to RSSI timing systems. The custom timing modules, coupled with a significant amount of processing power on-board, and some highly refined curve-fitting algorithms , help to run races without an engineer present. The one limitation that we will be very honest about is running the system in indoor environments which are in the ‘RF Hell’ category. Buildings with huge amounts of metal, roofs, walls, etc.
