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.
The LapRF Event System uses a milled, anodized, waterproof housing, which keeps electronics
protected from dust, and moisture, which appears to be attracted to FPV events (especially those
held on the Spanish isle of Ibiza).
This housing also acts as a heatsink to keep the sensitive timing receivers cool, and ensuring that
they have a long working life.
When placed in direct sunshine, at elevated temperatures, the effectiveness of this heatsink is
reduced, so care does need to be taken.
Simply protect the LapRF from direct sunlight, using anything that is transparent to RF. A piece of
white fabric, a pizza-box lid (ideally with tomato sauce removed), even the cardboard box that the
product ships in.
Placement
The lapRF’s integrated patch antennas form a beam which emits from the top of the product.
Ideal placement is in the center of the gate, but that does expose it to strikes from low-flying (high
speed) racers.
A small hole in the ground works well to protect it for grass tracks, or where this is not possible,
either protect the timer from strikes placing a solid object in front of it, or place the timer at a 45
degree angle from one corner of the gate.
When laying out tracks for RF timing, avoid parts of the track which come close to the timing gate to
prevent false readings.
For start grid positioning, place it at least 5m from the gate to ensure that the first crossing is
registered.
