Let's see you run a business of this size and try to make every deadline. It's difficult.

And they have to a certain way around if I'm not mistaken, to reduce friction further.

Great gearbox, and I'll definitely be using a modified version for myself. Could you show a picture with all the shifting mechanism hidden so I can see the gears clearly?

@Lipko - I'm not into the geometry details, and all that, but some features are a must for me. @Piterx - Cheers mate! I've got some plans (proper ones now) for a hybrid of yours and Sheepo's gearbox. I'm sticking to 3+R so I'll be using your gear setup. Thanks again everyone!

I'll fill everyone in on where I am. I wanted to create a Ford F150, but after many different axle designs, soon gave up. I then decided to build my own super car, which is currently being designed. The idea was to create something amazing, with many different features, most unecesary but there for realism. I'm still trying to find a way around it, but my options are running out. All along, I wanted something that could be enjoyed with and without PF to the same extent. This would include a working gearstick, working pedals, so when they are pressed, the said action does it's job (obviously not the accelerator). The PF system would be able to be implemented into the car very easily once the model would already be built, so it would be easy to convert it either way. The annoying thing is, I have each section planned out in my head (except the gearbox but now with the aid of Sheepo's design it should be coming along) but when putting it onto LDD it just isn't coming out quite as I wanted. Each mechanism has such a simple design, but it is really starting to annoy me now, that this gearbox is causing all this hassle. There's the car really, nothing that has never been done before, but some big ideas all the same.

That's a really nice gearbox Jon and with some modification it could be brilliant. I' am going to stick with a manual though.

Thanks for all the help. Yes, realism is what I'm going for. It doesn't need brakes, but it's got them. It doesn't need working pedals, but it'll have them. My plan for now is to just have a simple manual gearbox, and maybe branch out at some point. Using a 4 speed sequential could be useful too.

There must be away, of gearing the XL motors up, to reduce torque, for the purposes of the gearbox. Then, gear them down again. I don't know to what extent, but does anyone think that would work?

It's been done. Sheepo has done it, so how come his gears don't get stripped?

This challenge is one that I have tried many times, and most certainly failed. Unlike other challenges, this requires huge levels of skill, talent and engineering ability. Which clearly, I don't have. Anyway, onto the problem in hand. I am designing a car, a supercar in fact, with brakes and such like, which I am more than happy with. But then it comes to the gearbox. The hardest bit of all. I can't do it. So. The challenge is, can people design a gearbox for the car to win..... The pride of having your gearbox in my car. So, what I need from it. 5 speed with reverse To fit (obviously) To be able to handle the torque of 2 XL motors To be shifted from gear to gear, using one motor only. The position of the gearbox is up to whoever designs it but remember. There will be some front overhang as well, but a chassis section for this hasn't been implemented yet. Also, this is just the basis for a chassis. It needs a LOT of reinforcing. The car will have a functional cockpit (working pedals etc) A flat 6 or V8 engine will be mounted in the front of the car I need space for mechanisms and motors. The simpler the better, and the more compact the better. Now, off with y'all to see what can be thought of. If only I knew how to post an LXF file on here...

My personal favourite... The impossible universal joint.

A very nice technic set, with a great review! I'll look forward to the release of this.

Couldn't you use both together to combat that problem. That should work with it being a differential gearbox.

Couldn't you use a differential gearbox with one M motor and one XL motor? You'd have torque and power when you want them that way.

I take it you mean they are. They aren't available for individual sale, but they are apparent in the Crawler set(s)

How do you guys know what your number is?

Very nice car. I've always liked the Ken Block cars, so well done!

What I mean is, the battery boxes power adjuster would be controlled by the same motor that drives the car, but would be geared down. Then, to stop it from damaging the battery box, I would have a 24 tooth clutch gear in between the motor and the battery box. Now that all of that has been solved, I just need to think of a way to return the power adjuster back to zero.

That wouldn't really be an option, but thanks anyway.

Thanks for the help, I'll take all of that on board. Now the only problem is returning it to the neutral position when no power is being given.

I'm having that too, but in a normal car, you don't press the accelerator and suddenly go the top speed in that gear. I want the car to start off slowly, and accelerate up to the speed.

I'm in the process of building a MOC car, which I want to have as many features as possible. I know that Sheepo has made a way of his Supercar 2011 accelerating more like a real car. I would also like to do this, and have half of an idea how to. Using the rechargeable battery box, and the cars drive motors, it would be possible to gradually change the settings of the power controller, to slower deliver more power to the motors. The only two problems I have are; It would need a way of stopping when maximum power was reached, otherwise parts would get damaged. The other is returning to 0 power once the accelerator is not being pressed. Does anyone have a solution?

I saw that quite a while ago. It's a very odd sort of vehicle/bike/thing. If only it was made 100% of Lego. It is great though

Looks great and has some good offroad capability. Maybe you could add some gear reduction to the steering so you have more control.

It's great to see him get this sort of credit that he deserves. Well done Sheepo! These models have inspired me to do things with Lego, that I wouldn't have thought possible previously. His influence shows in the model I'm designing at the moment.
