C. Scrutiny Officials (SO)
SO consists of 2 officials, to spot and to check or note down car details on each participant's
Scrutiny Form (SF). They also have to be familiar with the RCDA car boundaries.
SO could be activated in these occasions:
- registration stage
- random & result verification
- receiving report and verify changes (made by participants on their car specifications).
- Passing and collecting SFs to and from judges.
all changes pertaining participant's car has to be recorded in Scrutiny Form.
Scrutiny on Registration Stage
First stage of Scrutiny has to be done during registration or day 1 when participants reporting in.
The scrutiny will note down details of the following:
- Chassis (Brand, Model, Material)
Material of bottom deck and top deck if any, statement would be e.g: Carbon Fiber, Fiber glass, Plastic, etc.
- Motor (Brand, Type & Model)
besides motor, note has to be done as well on cooling devices.
- ESC (Brand & Model)
- Any additional devices on board
any electronics or mechanical devices, allowed or not allowed as stated in car boundaries guidelines.
- Battery (Brand, Type, Capacity & voltage)
reliable voltmeter is required on site, preferably calibrated digital such as Fluke.
- Tires (Brand & Model)
If open tires are allowed, maximum tire width is 28mm and diameter is 63mm. - Weight (gram)
proper and calibrated weighing scale preferably digital is required on site.
Car has to be in full loaded state or how it will be in running condition.
- Car Width (mm)
proper rulers or fix gauge is required on site. Fix or pre made gauge with maximum width allowed will
help in reducing scrutiny time.
Scrutiny on Random & Result Stage

Passing and collecting SFs to and from judges
SOs will be responsible to make ready and pass the SFs to judges prior to particular car turn to run.
Thereafter finishing the run, SO will collect back the SFs.
All SFs has to be under the care of SOs. Tire Check (only applicable with control tire scheme)

---
EBS
IQS will be followed with EBS top 32 or top 16.
GS will be followed with either EBS top 16 or Top 8
Competitors with the same score will not share a position and only 16 will go through.
If positions are tied for the 16th spot, a low key battle will take place to see who goes through to the top 16.
Wild card entry could be considered if sometimes in the qualifying round it ended up having 2 to 3 guys eliminated
or failed to qualify to either the top 8 or top 16.
Match them up to bottom 2 or 3 who qualified (6-8th or 14-16th position). Bottom qualifiers have to defend their
qualification against these wildcards.
W1 vs Q6 (or Q14)
W2 vs Q7 (or Q15)
W3 vs Q8 (or Q16)
Drivers in the top 16 will battle each other with each driver leading for 2 laps, with a total of 4 laps.
(This can be decided depending on the layout and length of the course).
Format:
Top 16
1-16
8-9
4-13
5-12
2-15
7-10
3-14
6-11
The finals will be run with a total of 8 laps depending on course layout. Each driver leads for 4 laps.
If drivers are scored evenly, then a sudden death round of 2 laps each will take place.
Drivers battle each other and each driver starts off with 5 points. For each mistake the driver makes,
points will be lost, and handed to the opposing driver, e.g., if a driver washes out, then the score becomes
6-4 to the other driver. And so on. If the OTHER driver makes the same mistake, the points then equal out
