The Caterhan Seven (also called Caterham 7) is the present version of the original Lotus Seven (or Lotus 7) designed by Colin Champan in 1957.
This car is very famous because it is extremly ligth, and it has outstanding dinamic specs, which make this car perfect for its use in competition and track days.
This creation is made in scale 1:7. Thus remains in 29 studs wide, 56 of length and 20 fo high(23x45x16cm).
The weigth is 2.2kgs.
It has around 2500 parts.
As all my MOCs, this includes some remote controlled functions:
- Steering (PF M motor)
- Drive (PF 2XL motors)
- Sequential 5+R speeds gearbox (PF Servo motor)
- Disc brakes (PF M motor)
This car arrives with a 5+R speeds version of the all-new 3th generation of my sequential gearboxes. The new generation is even more compact and reliable. Of course it has auto.clutch
The speeds ratio:
R - 2.08:1
1 - 1.67:1
2 - 1.25:1
3 - 1:1
4 - 1:1.33
5 - 1:1.67
It has a gear indicator in the cabin.
Just behind the seats, over the rear axle are the battery and the drive motors (2XL)
The Seven design is based in a tubular unibody frame with double wishbone front independent suspension and DeDion rear live axle.
The front axle is double wishbone type with caster angle, camber angle and ackerman steering.
The original Lotus 7 had a typical rear live axle, and the newest and powerfull version has independent suspension , but the most common rear axle is the DeDion axle. Like the real one, this creation has rear 3-links DeDion axle(you can see it in more detail in the video)
The "most wanted" picture.
This creationa also has working brakes in all wheels(the same brakes used in my Land-Rover)
Like the real Seven, this creation mantains the unibody frame. Also to reduce the weigth, the frame and the bodywork are the same thing. The yellow liftarms in both sides of the car are the bodywork, but at the same time are the frame of the car.
You can remove in 2 minutes the bonnet, the drive train and the brakes lever, and then you will get this:
This picture shows how the structure is made
I hope you like it!!
