As announced a few weeks ago in my first attempt to come back after many long years of Lego diet (here), I managed to build my own Formula 1 racer.
Of course inspired by the great 8458 and 8461 models released by Lego, and more recently by the new Ferrari 1:10 set 8386, the challenge was not only to built a Formula 1 model, but also to get closer to the true spirit of Formula 1 car.
People interested in Formula 1 know that these cars are quite giant Lego sets : remember that in less than 1 hour, mechanists are able to completely disassemble engine / gearbox / cockpit as the construct is very modular…
Basically, the architecture of commercial Formula-1 Lego sets was completely the opposite : stiffness of the chassis is of course a key factor so that every subsystem (engine, gearbox, chassis, suspension) is completely “mixed” with each other in a rigid, but non realistic whole… Modular architecture was really the main requirement.
Of course, I was also disappointed by other lacks in existing Lego sets :
- Articulated hatch is funny, but obviously not realistic…
- No gearbox !!!
- No suspension for 8386 set !
So the basic constraints for the model were the following :
1) Having a really modular architecture ; from rear to front :
- Rear suspension over differential cage
- Rigid Gearbox between differential and engine
- V12 Engine
- Main chassis : from engine front side to pilot’s pedals
- Front chassis and front suspension
2) Having a gearbox (4 speed only): a little disappointment, but anyway the best compromise between size / integration : it is nearly impossible to built a 6 or 7 speed GB in an approximately 1:8 scale racer, with 2 major issues :
1-dimensions of the gearbox chassis had to be 7x5 studs max
2-changing gears from the cockpit had to be done in a simple way
3) Massive use of new-style technic parts (studless) : I like them and they significantly help to build complex assembly in tiny space
4) Front and rear push-rod activated suspensions
5) Ferrari-style (I like red cars...)
For the first time, I tried to build the model mixing real construct and CAD design with Ldraw : quite interesting, although playing with real parts is still the most efficient way… The good news for people interested in the model is that Ldraw files help understanding the construct and also confirm my “modular” approach.
The Brickshelf gallery will be soon completed with real pictures of the car.
Very nice! I'm thinking of building one myself, would you happen to have instructions at all? I could probably build this entire model using the Ferrari 599 GTB.... I think that should be a sufficient enough model...
Incredible. Awsome engineering. This is what I envisioned when I got hooked on the Lego Technic system 6 months ago. Thank you for posting such a marvelous model. (additional notes) Could the gearbox be sequential? Could you post or send a picture of the front suspension w/out the wheel?
