LapRF Setup
The lapRF setup page is where the number of active pilots is set, plus the band and channel that each
pilot is using.
In addition, the power level used for the race (all pilots should ideally use the same vTx power) is set
here, along with a ‘sensitivity tweak’ which works a bit like the exposure correction on most high-end
cameras.
If you are missing laps, increase sensitivity, if you are getting false hits, decrease it.
This is a good time to talk about pilot count, and its effect on resolution/accuracy/gate speed.
The personal time has a single timing module, which scans each of the active channels.
When a single pilot is enabled, the RF signal is ‘sampled’ at the maximum rate, and supports quads
flying through the start/finish gate at over 160km/h.
When a second pilot is enabled, the timing module has to toggle between the two channels, reducing
the accuracy of each channel, and decreasing maximum gate speed.
In practice, for 250 sized quads, with pilots of typical skill level, 4 pilots can easily share a single lap
timer.
For slower quads, tiny-whoop class for example, even more pilot slots may be enabled.
For the best accuracy at 200km/h+ gate speeds, and up to 16 pilots, the lapRF Event system is a
better choice, and should be used for larger events.
