Tire quantity rules for EOS Hudy Arena will follow on time before the event

2WD FRONT TIRE RULE

Changing the wheel diameter by gluing the front tires down to the wheel rims is NOT allowed.
You can apply some CA-glue to the outside of the tire to change the handling of the car, but you can NOT glut them down onto the rims.

POWER SUPPLIES

All power supplies MUST have a CE sign on the case. Otherwise, they are not allowed to use at the EOS.

BATTERIES

EOS allows any 2S hard case LiPo battery packs. Every LiPo has to be charged in a special charging bag.
Max. battery voltage: 8.40 volts / Max. charging current: 12 amps / Max. discharging current: 20 amps.

These maximum charging and discharging currents are counting for the whole charger, not for a single channel of a charger. So if you use two channels in simultaneous mode, the total current arriving at the lipo battery is limited to a maximum of 12 amps for charging and 20 amps for discharging – and not more! It is not allowed to use two channels at 12 amps each to charge one lipo battery– that would be a charging current of 24 amps in total and is strictly forbidden. It is also not allowed to use any kind of battery warmers to lower the internal resistance of the lipo pack before and during the charging process.

If a driver comes to technical inspection with 8.44 volts or more he is not allowed to start in his next heat. When the battery voltage is from 8.41 to 8.43 volts the driver is allowed to discharge the battery down to 8.40 volts by accelerating and braking the car while holding it in his hands until the battery voltage is down to 8.40V.

ELECTRONICS

The use of a Gyro or other electronic driving aids are not allowed.

ADDITIVE

No tire additives are allowed.

MOTOR RULES FOR STOCK CLASSES

Motors are handled out in a raffle, meaning you will not receive the same motor at each race. It is absolutely forbidden to open the motors. After the race weekend (on Sunday) motors must be returned. The rental fee for the Stock Class motors is included in the Stock Classes entry fee.
