Lap timer for better training sessions!
It doesn’t get much easier. Power on the LapRF, drop it in the start/finish gate,
select its ID in the free Android/iOS app, select the number of pilots, and video channels used, and start racing.
The LapRF will run all day, measuring lap times and speaking the results. There is no better tool to allow pilots to measure their performance, and work to improve it
The lapRF uses the Radio Frequency energy emitted by the Video Transmitter on the model to detect its presence within the race gate.
The current generation of racing drones have two things in common, they all use 5.8GHz video downlinks, and they all need to be on different channels to race together. This is all that the lapRF system needs to precisely time events.
No RFID transponders, no Infra-Red transponders, no complex installations. Just place the lapRF system in the start/finish gate, and start racing.
Bluetooth Link to Phones and Tablets
The LapRF Personal Timing System includes a bluetooth module which can quickly link an iOS or Android device to the gate.
Enter pilot names, start the race, and the lap times will be spoken along with the pilot’s name.
All lap times will be shown in a table, along with average, and best lap times.
Personal… but Sharable
The LapRF Personal Timer was designed to be used by one pilot, that is where it is the most precise. But if you want to invite a few friends along for a quick race around the park, we support that too, out of the box.
No need to figure out how to interface your mates timers together, or run multiple apps, just share yours.
Timing resolution (which is more than enough with one pilot) decreases as you add more pilots, but when you start with more than enough, and share, you end up with just enough 🙂
Integrated 2600mAh Battery
Integrating a high capacity, but common 18650 battery (available from vape shops worldwide) the LapRF doesn’t need an external power supply.
To allow quick in-the-field replacements, we included a handy battery door in the bottom of the unit, minimizing down time during battery changes.
When it is time to recharge the battery, the integrated charger just requires a USB hookup, no need to remove the battery.
Custom Timing Receivers
Instead of using a standard receiver module in the 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.
To top it all off, we designed custom antennas with gate-shaped beams which let you precisely define the detection area of the timing system (something that competitive units sorely lack). These antennas are designed for RHCP/LHCP, and Linear polarization, covering everything that will be seen at a race event.
The high-end version of the lapRF, the Event timing system (which will be announced in more detail shortly), includes an Ethernet port to allow direct cabling of the timing system into race management systems.
Evaluated for > 6 months by none other than Joe Scully, the best race commentator in the business, and used for the vast majority of his events. Joe’s feedback was instrumental in ensuring that this timing system meets the needs of FPV race organizers.
(And of course, IP67 waterproof, passively cooled, with no fans to suck in stray vegetation, commonly found at FPV race courses)
The ImmersionRC LapRF Race Timing Systems are both supported by the industry-leading LiveTime Scoring Engine.
Full integration of the personal system via USB, or the event system via Ethernet, including full auto-calibration of the timing system, and even a built-in Spectrum Analyzer to analyze event background noise.
