Most answers can be found in our Rulebook with a quick search.

However, if there’s some ambiguity or your question is very specific, or even if you’re looking for technical advice on your build, our tech team is here to help – submit your question here.


Q.

I am looking to enter an open-class kart, and I was wondering if I could use a motor that exceeds the power limit, as I have found them easier to source.

A.

You’re welcome to use a larger motor, but your motor controller can not be rated above the power limit.
For example, a 2.2kW motor paired with a 2kW controller is actually a great setup, as it’s good practice to have a bit of headroom for your motor. 


Q.

How do we ensure our vehicle can connect to the ECU on race day?

A.

The ECU uses XT90 connectors. Ensure that you have these in your circuit after your kill switch (so that the ECU is also turned off when you power down). Full details on where to find these and how to connect your circuit can be found in our Energy Monitor / ECU section.


Q.

What restrictions are there on vehicle dimensions?

A.

There are no restrictions on vehicle dimensions.


Q.

Can I build my vehicle out of wood?

A.

Absolutely! However, consider rule VR.4.3.1, which states that your roll hoop must be strong enough to maintain its shape in a collision. Your roll hoop shouldn’t be made of wood, as it is generally not strong enough to protect the driver during an accident.


Q.

Do we need a seatbelt?

A.

This is no longer a requirement, but if your vehicle performs at a level where a seatbelt would be sensible, then it is suggested you include one.


Q.

We are looking to do a modular build, where parts can be added or removed as needed for each event. Is this allowed?

A.

No. Once scrutineering is complete, you are not allowed to make modifications to your vehicle.


Q.

Can my vehicle be radio-controlled?

A.

You’re welcome to make a radio-controlled vehicle, but rule VR.3.3 states the driver must remain in contact with the seat while driving.


Q.

What are the dimensions of the Standard Kit batteries?

A.

180mm x 75mm x 165mm


Q.

How do I get replacement parts for the Standard Kit?

A.

Email your coordinator or submit an enquiry using the enquiry form.


Q.

We have acquired some healthy NiMH hybrid batteries and were wondering if we can use them for an Open Kart?

A.

The rules indeed do not mention NiMH batteries, mainly because they haven’t been used before. That said, they are perfectly fine and are a great battery to use.
