Near Brighton. though I’m currently going through the motions with the postal service as they have delivered my hub to the wrong place and can’t work out where they left it.

Worm gear is a great solution to this problem. One thing that was discussed on the other thread is the idea of having physical stops that take the stress out of the gear train and directly into the chassis

I’ll pop it on Lego ideas when it’s done lolz.

The whole point in us using internal combustion is the range, power and convenience of it. Petrol is just a convenient way to store the energy, why not focus your energy on using an air tank at hoggish pressure and use that as “fuel” to run an engine, you can still build all the valves etc but you take away the heat and solvent issues you will inevitably have from the off?

if I can lose four studs in length here then I think it’ll work. Engine seen here in rare mcv paint job (military colour vomit)

Lego and petrol are both essentially made of the same thing, The petrol will turn the bricks into a mixture a bit like napalm. Please film this!

I’ve been grappling with the engine pod structure for a couple of days and finally have a system for making a reasonable cylinder.

I saw the video of this bike on tlcb and it literally filled me with joy at lunchtime.

In my head putting one input on a diff at 390 and the other at 220 won’t make an output of 610. Is it not total output of 305 rpm? Putting two motors into a diff as inputs won’t double their speed at the output, it will output an average of the top speeds. l could be way off the mark with this though.

Thanks for that. The actuators were single acting on the set I had, I was tempted to buy the unimog from a few years back as it seems to contain everything I need but it’s eye wateringly expensive.

That looks fantastic! I thought it was a rat rod when I first saw the roof line. I have followed you on Flickr to see more pics of your creations. Are those wheels from the new Ducati? What diameter are they without tyres?

I figured I’d update this thread as I’m now considering pneumatics in my build as well. It seems they have come on a bit since the red excavator I had around 30 years ago. Is there a basic guide to the new system anywhere? I’m thinking of using a motorised pump to power pneumatic retracting undercarriage. Does the new system require an air tank? thanks for any help people can give me on this as I’m a bit out of touch. @HUWI I owe you a beer for saving me a pile of cash and time for the hub advice!

Nice, I love the 500. Such a pretty helicopter.

What do you fly?

I think there are fortunately a lot of brave buyers out there at the minute, supporting electric cars and creating demand for infrastructure. I think it’s either 2030 or 2035 when the aim is to not produce any more I/c engines. There’s a problem with image and just the pure glory of the internal combustion engine, in that the performance of electric vehicles can be terrifyingly quick, there’s no fire, no noise, and no drama. And those things are pretty well ingrained, though ultimately, pure self indulgence.

How old is old? I’m 45 but I have the knees of a 68 year old due to 39 years of skateboarding and the mind of a 12 year old due to my obsession with building things out of plastic bricks.

Those look excellent. How about some of these:

That’s brilliant! Nothing wrong with sneaking a cheeky bit of electronic wizardry in there either.

Wise words! I tend to work by drawing a scale sketch using the model scaler, then sketch it in technic. I’ve already gone pretty much back to square 1.5. Update pics. I’ve sorted the joystick and rudder pedals into rotary outputs.

Dammit. I already had homes for all the new dbg panels on this!

Yeah I’m trying to make the pods as much of a separate structure as I can. Fortunately the hawg has tonnes of dihedral after the pod and is flat before it so this should help too.

That’s a good point. I was going to basically build a big tricycle and then add wings but as soon as I get it standing I’ll sketch some wings on and see what happens.

Haha! Thanks for the kind words. It’s my favourite flying thing that doesn’t have rotor blades. There aren’t a huge amount of 40+ year old things in modern warfare. (The .50 cal browning and chinook spring to mind though) I was quite surprised it hadn’t been built in technic before as it is pretty square compared to a lot of modern jets, then I started the engine pods and found out why! Cheers. I’m a fan of “treebling” (technical greebling) and would much prefer to use a complex and unnecessary system of mechanics than a servo motor.
