Lego Technic RC Black Roadster MOC - FREE Building Instructions

This is a remote-controlled Roadster using Power Functions elements. It's an original, fictional model in the 1:10 scale.

Features:

- Rear wheel drive through a differential with a gear ratio of 1:1 and powered by two PF xl-motors

- Front wheels steering controlled by one PF servo motor

- Independent suspension on all 4 wheels

- Functional fake engine which can be run either manually (by pushing the car around); or on its own with a dedicated PF m-motor

- All doors are openable and semi automatic, after unlocked, they will open by themselves, just need to be closed manually.

- All doors have some kind of locking mechanism to keep them closed

- There is a switch below the car to engage or disengage the fake engine from the transmission allowing for a better RC performance

The transmission is the simplest I could get it to be, in order to reduce friction.

I also wanted to keep the steering as simple as possible, it's just a pinion and rack.

The independent front suspension requires a more complex build because I really wanted to use those F1 wishbone arms.

The independent rear suspension is also very simple to build.

The fake engine connection to the transmission is the most interesting mechanism. It can run on its own with the dedicated m-motor, but since it is connected to the transmission, when the car drives around, the fake engine accelerates accordingly. The direction of its spin will always be the same regardless of the car going forward or backward, the mechanism will automatically engage different gears in each situation, keeping the fake engine running smoothly in the same direction.

Now you just need to source the parts to build it.

I hope you enjoy this interesting and free MOC!
