I got curious about this and made this. When you spin the knob wheel it rotates the 24 tooth cog around the stationery 8, the outputs are the yellow spacers. You can change the hearing by swapping the order and size of the chain of three gears. At the moment each output does a full turn with every strike of the 24 tooth gear. The one below makes a 3/4 turn of each output but has a much smoother action and fewer snags by just using an offset gear on the central shaft.

I have a fairly compact distribution box that can spin however many axles you wish to add in either direction without changing the motor direction. It uses gear selectors so you can keep adding more outputs until friction and backlash get the better of you. I’ll put some pics up if you’re interested. Having watched your video you could do a circle of planetary gears and an off set gear in the centre that contacted the planet gears in sequence as it spins.

Yeah that would work. There’s a 3l radar dish if you wanted to close off the ends too

You’d likely have to find a wheel that is 3l and use that as a core.

You could use a 3l cylinder and clad it with lift arms held by threading a rubber band through the holes or by using soft axles threaded through them. another possibility is to use tracks around a smallIsh cog then join onto the holes in the tracks. This might be a bit tricky at that scale though.

I’ve torn this back to square one now as some fundamental issues were better solved by starting over than by continuing to modify what I had. fuselage is now a series of 5x7 frames made into a long box section using panels as I need the maximum space inside for all the controls. https://flic.kr/p/2jN34EZ https://flic.kr/p/2jN3RcB https://flic.kr/p/2jN34ir

I believe that’s known as McDrifting.

Bucket wheel excavators make a nice stockpile of parts. Used ones are on eBay all the time.

Chuck some tape on the back tyres and try it, that could be the answer to what you’re looking for. The lack of grip at the back will take the load off the gears too. Definitely lock the rear diff!

Fantastic!! I really like the canopy movement too.

You could always buy some drift rc tyres in a compatible size to get the back to break away easier.

You could go 4wd but “weld up the rear diff“, that can be lots of fun on a smooth surface.

Absolutely. I get huge amounts of mental tranquility from tinkering and building. Plus, the things that really need working out, ie backlash and friction, need a physical sketch as they don’t show up in virtual building. I’m currently wondering whether to do the longer control routes like on the alouette 2. Using worm gears with a loop of Lego string joining them. Maybe the worm and a bit of tension might work.

having worked out roughly how to build this it’s now being rebuilt from the ground up using less chaos and more 5x7 frames. I’ve also had to rebuild the control deck so there was more clearance below it for the gundercarriage, placing the linkage from the joystick under the seat instead of under the cockpit floor.

Off the top of my head you could drive your power take offs using a gear selector ring and two red gears but input through the centre shaft and output from the red cog on either end of it. The shaft would be constantly rotating and then you could engage either red cog and take the outputs from those. https://images.app.goo.gl/hXManm3rYY9nQUTm8

I literally thought the first pic was of the real thing!

Lego 8880 wheels provide a slightly better kingpin solution, it’s a shame that a, they’re quite pricey and b, you’re kind of restricted to their hub. You can get a fair bit of flexibility and unusual kingpin placement using the swash plate part as a hub as it has 4 ball joints attached so you can make a virtual pivot point using these. i really like the use of seat panels right along your bodywork, it makes it a really consistent looking model. Also, those inner wing curved panels look so right. They really set the engine bay off. I’d be absolutely delighted if I’d come up with any of the technical and cosmetic features on this model, illegal or not. So long as the lego police don’t find out where you live it’s all good.

Bloke builds real crane out of loads of toy cranes! Amazing stuff!

Nice! I like your compact steering solution.

volumetric cement lorry. These have tonnes of working features that would make a great build.

I love the radial engine! Do you have any more pics of it?

Bricklink, careful though. It’s like the best sweet shop you’ve ever seen
