Landing Gear

[captainmib]

I want to recreate the mechanic in this video, starting at 1:14, in the smallest scale possible. 

Is there a way to do this without gears? Is this even possible with Lego?

Ideas will be much appreciated.

Of course it is possible. The mechanism in the Video does not include any gears. So why to use it in the Lego version. Its just a clever mechanism based on levers. Just try to copy it 1:1.

With gears i mean that i know a standard solution where you use gears to turn the wheel.

I tried copying it, but i'm not a mechanical wonder, and can't figure it out.

You could use some pushrod that rotates the wheel. Even a steering link with two towballs, maybe.

I think i found a solution. 

Will post a pic later.

Unfortunately, there are only long parts that can connect to towballs...

I think i found a simple and effective solution.

Keep it simple, right?

This looks sweet! Gotta build me one of these landing gears in real bricks for sure! I just hope it will be strong enough to keep some weight... Doesn't look that strong on first sight with all the connectors etc. I was thinking about something like this during TC15 design phase, more specifically the Vought F4U Corsair, but the system you chose seems 'simpler' to replicate in Lego.

Thanks!

I have it build here, it works great.

So far it seems pretty robust. Weight may or may not be a problem. Weight pushing down on an axle should not really be a problem i think?

Built it myself just now as well, works like a charm. I swapped a few blue axle pins with friction to the tan axle pins without friction to make it move smoother, does not seem to impact the strength at all.

Great little mechanism!
