Simple Lego Differential Car Application, rear wheel drive with power function

This is a simple, but strong, fast and adaptable Lego car using the Lego differential gears and power function motors. Works great and is a good platform to bulid whatever you want on it. The steering is from a Technic truck design adapted for power function motors. It attaches to the normal Lego beam with holes using the Technic black connectors. This is later reinforced with beams on top. Very strong. The steering has a clutch/slip gear so you can't oversteer the wheels.

After watching that, I almost understood how the oversteering system worked... I need to get hold of one of those white clutch gears and figure out what's going on!

is'it the m motor not supposed to move wen u steer

Oh my gosh, thank you so much. I needed this info quick. So i should just buy a XL motor? My model is pretty small but idk if the xl will be too much for it.

with xl you could drive outdoors with speed but it weights quite alot (use like 1:1-1:3)

with medium you get guite much speed but it has abit too low torque with 1:1 (use with 1:1-3:1)

this car uses m for steering (usually every car uses m for steering) and this car also uses m for drive with 3:1 gearing, its all easy to see on the video. id suggest you to buy xl its quite large and heavy, but youll get used to it and it delivers huge torque for later models..

what motor is this? M or XL, because im making a car a little smaller than this its not THAT heavy and i was wondering if i should buy a xl or m.

I designed a gearbox that goes up to 2400 RPM top speed with the medium motor. It's really good for racing and off road areas, because it's sped up offroad using a complicated contraption.

Nice!

I made a lego car a few years ago (3, I think, though I did not disassemble it), too, though mine isn't as tough-looking or as fast as yours. Your kit seems a lot newer than mine, and your motor a lot stronger.

I used the same principle for the steering, but I used an axle for the powertrain instead of gears.

If I get my camera, I'll film it and send a link to you.

Thanks for the video!
