    Steering on a 6x6 design

    Could you make it so that front steers 2x middle and rear mirrors middle?

    Thanks for posting these designs up. Although I haven’t built them directly, your approach to building and explanations of why things do what they do in terms of, for example: torque sensing, has given me a much greater understanding of how to design and build stuff that actually works. basically, I owe you a beer.
  3. I reckon that’s the right attitude to have. Lego is never going to be a100% accurate representation, it’s almost like a caricature so as long as you get the overall proportions and the key features then you can add Lego personality to it in spades. regarding scale, your benchmark measurement is wheel size. You only have a few options there and as 80’s rally cars tend to roll on smaller wheels it will affect the scale you eventually produce the model at. the 8880 wheels happened to be the perfect size and shape for me to build the car at 1:7 scale. Scale is just a number to allow you to have a common factor to make size decisions on. So for example, if you put a side view of the beast into sariels scaler and you know that the wheel you are using is say 10 studs high. Draw that dimension onto the scaler and it will then proportion all the other measurements you make from the drawing accordingly. I hope that helps. I’ll be following this build as I ‘kin love group B. It was basically wacky races in real life and contained the kind of reckless lunacy and shed engineering that I wish more motorsport had. Sure people died but that’s a small price to pay for seeing a 700bhp car doing 140mph down a farm track covered in people with fire coming out of the exhaust.

    I’d probably have used system for them if tlg made a 4x4 curved piece with a curved top but they only do a 3x3 so I think it would have looked bitty. mom open to suggestions though.
  5. I’ve been thinking about this for a few days, I reckon that the whole point in building Mocs is that there’s always another turn of the screw to be made. I mean the whole process, if you’re a grownup is basically relaxation/distraction so why not tinker? It’s not like it’s important. I know for a fact that whilst my rs200 is “finished”, there’s a few things I’d change, and one day I will. The beauty of Lego is the finish line is totally flexible. Maybe a moc is only finished when it’s been photographed and dismantled.

    Yeah I’ve tried loads of things like wheel rims and curved bricks but that way seems the best, especially in terms of getting rotating parts inside. Luckily the Hawg is pig ugly in real life so the model gets a bit of slack in that department. I tried using curved panels when I first started building it but they didn’t work as well as using the radial parts inside.

    Yeah I know man, I’m not up for using system for them and I figured I’d use a similar technique on other areas like the nose so as to make them fit in as a building style. If I can get the ends to blend in more I think it’ll help. If anyone has any suggestions I’m all ears.

    I’ve had a busy weekend and redesigned the retract system, the rears now have a single common worm drive in the fuselage. They don’t lock but the force taken through the leg when the plane is stood on it is three studs behind the pivot point and it pushes directly on the main spar. I’ve slimmed out the back of the fuselage as it was too bulky before and built the nacelles into one solid unit. I still need to work on the reliability of the front retract as it often catches on the side of the door. It also needs moving one tooth round on the worm gear as it needs to be more vertical. I’m pleased with the stance of the plane, redesigning the undercarriage forced me to address that issue.
  9. I’d recommend using the wheels from 8880 on it as those are way too wide for an 80’s car, even a group b monster like that.
  10. I’ve had this exact issue and went for a three tone camo scheme of lbg dbg and black to get around it. Maybe you could go camo?

    Those brown three way connectors are great, especially combined with the axle version. I really struggled to make radial and round objects without them. Great advice. I’m going to have a look at those. Fortunately the A10 has really simple robust undercarriage and the rears do not fully retract so you can land with the wheels up. The undercarriage doors are directly linked to the leg so they can be blown down by the wind if the system fails. Here’s the original design with the worm gear in each pod and the new version which is much simpler and works so much better. and the new version with a more appropriate door design too. Thanks for looking.

    I’ve made the decision today to re design the rear retract mechanism. At the moment I have low torque high speed coming from the central distribution box and a low profile worm drive mechanism in each wheel pod. This relies heavily on thin bevel gears and they snap easily. Also, it’s very tricky to get them synchronised with each other. I plan to move the worm mechanism to a single one in the centre of the fuselage at wing height, then undercarriage driven with one axle out to each pod. I think it will need a locking mechanism too. Also, I’ve made the turbofans completely modular and they can be removed intact in the spirit of the real plane. All control surfaces are interchangeable with their opposite counterparts. Same with the engines. Pics of revised undercarriage to come.

    I think the Porsche 944 had a rear mounted gearbox and a front mounted engine, as did some Alfa’s. Ford did the opposite with the rs200 and it has a mid engine with prop shaft running to the front mounted gearbox.
