FPV and quad racing just entered into a new era. For those who participated in earlier races, it was always a hassle to mount some kind of transponder right before the race on their quads. Now during the races many of these got damaged and often many of them got lost as they have fallen off from the racers. The IR based sensor often did not pick up the passing quads because these were either too fast to detect – or just the sun simply changed positon and blinded the sensors.
The introduction of the RSSI based race timing systems managed to eliminate the above problems. No more transponders, no more problem with the sun shining in the IR sensor. The RSSI based timing systems lock on the video frequency of your FPV racer and detect the maximum signal strength as it passes through the gate under which the race timer is placed. While the personal race timers like the LapRF have only one receiver built in and was designed to pick up the signal from one quad – or time sharing with 2-3 racers, the 8-way event timer system has 8 individual 5.8Ghz receivers where every single one will be dedicated to measuring one individual racer. This increases the accuracy of the measurement dramatically above other systems.
Instead of using a standard receiver module in their 8-way timing system, ImmersionRC’s hardware engineering team designed a custom module, which can be calibrated on-the-fly to adapt to the different power levels found in races. Sensitive enough to detect passing quads, but selective enough to ignore adjacent channel interference. Heavily filtered to ignore off-band interference common at race events.
They also designed custom antennas with gate-shaped beams which let the race director precisely define the detection area of the timing system. These antennas are designed for RHCP/LHCP, and Linear polarization, covering everything that will be seen at a race event. To adds to the above benefits, the LapRF is just as comfortable in the digital world as analog. Many successful mixed Analog and Digital races have been run by race director Joe Scully with a great deal of success. The Connex Prosight transmitter signal is just as precisely detected as the analog TrampHV video signal. The Prosight TX units must be in fixed-frequency mode in order to properly work with the 8-way LapRF.
At the time of this writing, the software a race director should run to properly benefit from the advantages of the 8-way LapRF race timing system is the LiveFPV scoring engine from LiveTime. ImmersionRC worked with the folks from LiveTime to improve the integration and support for the 8-way LapRF with their scoring engine. Joe Scully has run numerous races using these two systems and we could all benefit from the precise lap timing and race management of these two systems.
We also equipped the Fatshark RCC (Race Command Center) with an 8-way LapRF, and this way the FatShark Race Command Center can just show up anywhere, it takes about 30 minutes to deploy and connect the receivers and external equipment, then it is ready to race, This is the race flight line on wheels, it can be ready to race within 30 minutes of arrival. Please take a peak of the special 4 way Scorpion diversity receivers lined up on the side:
The 8-way LapRF is now available from New Generation Hobbies, please click on the ling below to purchase it:
Here is an update to this page after we received the first shipment. I prepared an unboxing video which was streamed live to Facebook and YouTube as well. Please check out the unboxing video below:
