This is a minimal (482 sections) and quick cart, with a topspeed of ~9km/h, utilizing 2 L-engines for drive. It utilizes 1 servomotor for controlling and has 2 LEDs on head of its rooftop.
It guides smooth, even at high speeds (now and then it floats a piece however). The increasing speed is better than average, however you will require about 10m of level, smooth ground to arrive at its topspeed.
It is very solid. Be that as it may, each once in for some time, you have to attach the controlling component ? by squeezing against the calculated liftarms-and its equipping ? by squeezing against the sides close to the back wheels.
