For this MOC, the difficulty was to insert the electric components but to have a light and good design. The choice of a buggy was chose because the design is quite light, and it is more simple to have a good performance.
I have made custom stickers to have a better look.
Steering is done by a servomotor.
Driving is done by 2 L motors. It is better performant than just 1 XL, because 2 L have a better acceleration and more power. And they were easier to place Inside the chasis.
The suspension is very efficiency. It is smooth and reactive.
At front, there is independent susension. At rear, there is a suspended axle.
The chasis is very, very light. The basis is done around just 4 beams.
The complete buggy (train's battery box included) weights 495 grams.
