Hello, and welcome to the Calday Cheetahs 4x4 Team Design and Planning Portfolio. We are a Class 2 (First time) team and have used the 4x4 In Schools Starter Kit which contains the basic chassis and includes batteries as well as a standard remote controller. We then built our own body shell using a vacuum former as well as a custom lighting system using bright white LEDs. We used some of the money from IDS’s sponsorship to give our vehicle full articulation and steering going to all four wheels, we designed a circuit to switch on extra lighting when the vehicle went into a dark area and designed a rudimentary tilt switch consisting of a wire with a weight on the end connected to one end of a circuit and a conductive metal box connected to the other. When the weighted wire touches the sides of the box it completes the circuit and triggers a buzzer.

The base of the vehicle is the Losi 1:18 scale Mini Rock Crawler provided with the Starter Kit from Kit Stop in Birkenhead, which also includes the necessary 2.4MHz remote control unit, 7.2V battery pack (1700 milliamp hours) and matching charger for the battery. We chose to design the car’s body in 3D using SolidWorks software to give us a good idea with what we wanted to end up with at the end of the vac-forming process and to help create the foam model with which to use with the vacuum former to create the body shell. The vehicle has been modified to allow for the customized lighting system that switches on when the car enters a dark area and to let us fit the tilt switch and buzzer. We were initially planning to run the additional circuitry from the vehicle’s power pack, but then realised that this would be difficult and that two single AA-battery holders would do the job instead.


The base car that we would base our 4x4 Vehicle on went through a number of different design ideas before the conclusion. These are the stages mapped out.

Our original idea was too base the 4x4 on one certain car, for example the Lancia Stratos, Subaru Impreza WRX STI or Land Rover Defender. So we created a mood board of pictures and drawings of cars we could base it on.

We then thought of another idea which was to combine the two best car ideas together, the Lancia Stratos and the Land Rover Defender. We created the concept design (Above) but after some discussion, decided this design idea was too silly and thus the concept was terminated.

Our final design - and the one we used for the completed car - was of the new, 2011 redesigned Stratos. Our version would be modified slightly from the normal road car.


To give us a design edge, we dismantled our car and mapped out all individual parts on the 3D Design Program SolidWorks™ . This allows us to experiment with the car in a virtual world and therefore avoid damaging any parts when experimenting and to have a detailed computer design.

To map out our car, we dismantled all of the car and measured, catalogued and filed all of the components.

With the components from the deconstructed car, we used a combination of both the professional SolidWorks™ Computer Aided Design software and the open source Blender to create 3D renderings of each individual component.

With all of the parts created in 3D, we pooled them together and assembled the full 3D representation of the car.


We created the body for our car out of transparent PET (polyethylene terephthalate), a hard and strong plastic that is perfect for vacuum forming, due to it being a thermoplastic. The mould for the body was made out of HIPS, a cheap and easy to manipulate material. The mould was slightly tricky to make, due to the Lancia Stratos’s various curves and also stepped rear window


Using our leftover sponsorship money, we purchased five polo shirts at the total price of £9.00 from George at Asda, as well as a set of 5 T-shirt transfer papers from the user “signalinkjet” on eBay, for £3.30. We then designed our shirts, with the cheetah from our logo on the left of the front, and the crest of our school, Calday Grange Grammar, on the right. On the back of the shirt below the collar we put our full logo.

To market our team externally in a way accessible to most of the world (also to possibly attract overseas sponsorship) we created a website on the domain name and webhosting provided to us by Packet House Ltd (packethouse.com), at caldaycheetahs.net, we then proceeded to register a Facebook page and also a Twitter account, to keep others such as our sponsors and the general public up to date on the status of our team and the vehicle (the blog on the website also assisted us with this).

To aid in the marketing of our team online, we created a Facebook page, aiming to gain likes, and promote our sponsors by ‘liking’ their Facebook pages through ours (displayed in the bottom right of the screenshot)

To keep sponsors and others updated with the progress and news of our team, and to also provide marketing for the sponsors, we registered a Twitter page, that was embedded into the website.

Using the sponsorship we gained from Packet House, a webhosting company, we were able to create a fully customisable website. It shows news, contact and information for the team, including our sponsors and team sheet.
