[MOC] RC car with a neutral gear

[Parazels]

Normally, RC cars can't roll free, when an electric motor is off, due to reduction inside the motor.

As a result - no free rolling, no inertia. Sudden starting and stopping. Robotic movement.

In my RC car a clutch is automatically enabling/disabling, once the motor is on/off respectively. 

It's similar to a real life driving, where you can alternate acceleration and free rolling in a neutral gear.

1 PF L-motor for propulsion

1 PF Servo-motor for steering

Looks good, can you show the mechanism used for that?

Yes, later on instagram.

Can you explain me, how to make a visible YouTube link?

It should be automatically embedded

Thank you, but it didn't work. I added your link...

Did you use copy and paste?

Then I don't know why it isn't working, but since the video is added here everyone else can see it now.

Try again: take the link, remove the "s" from "https", and copy & paste it here. It should work (don't forget to press enter).

I love this! The fact that the differential disconnects is for playability, right? If yes, great idea!

Your link is the shortened version, you need the full one (the one you see in your browser bar, not the one you get from sharing it on mobile) Here's what you should paste for it to be automatically embedded:

Interesting idea with the freecoasting!

It's realistic. But it works better, if you have enough space to accelerate your car. Then it can roll by inertia.

My car is a concept. With a buggy motor and more precise steering the results would be more impressive.

This is how it works

I'll post the other demonstration video here:

@Parazels use this link instead of the shortened one:

Ah, thanks :-)

Amazing solution! I expected to see a similar thing but still wondered how it works for reverse too, as a single "cutch" works only is a single direction.

So, your idea is quite smart and compact. All genius things are too simple to be easily-invented

It remembers me the mechanism of the 9396 helicopter, very playable solution.

It is quite an interesting idea! I would say, though, that in a truly fast, buggy motor-powered vehicle, one might prefer an "engine brake" to the coasting ability, but the mechanism is still innovative and worth seeing!
