ImmersionRC LapRF Personal Race Timing System LAPRF1

Quickfind: 1291310 SKU: LAPRF1

Product Information

Easy To Use

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.

No More Transponders!

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.

Any loss of Bluetooth connection will not result in loss of lap times. When Bluetooth is reconnected, all missed lap times will be transferred to the app.

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.
