wow just wow

wow just wow

how is the gear lever connected to the frame? i can't really see in the pictures

This is just insane. I'm quoting: "My idea was to make a fully "drivable" car, meaning if we found someone small enough they could get in and drive it". That for me is a crazy idea. This is in a league of its own and therefore "excellent" seems rather modest.

I did use two 16 tooth non beveled gears for the third set of gears. 4th and 5th gear ratios are quite close (I rounded up a bit for 4th is actually 1:1.17) so it may appear that 4th and 5th are the same. When I did my test, because I thought initially there were only 5 speeds, I just started spinning the input and seen where the out out gear would stop. I observed that in 4th gear it would take about 8 turns for the red axle to return to its starting postion and 5th it would return to the same spot with one turn of the input indicating a 1:1 ratio. The other ratios are much easier to tell apart.

Tyler, perhaps you could explain a little more about how you achieved getting six speeds out of that gear box setup. I tried just adding another driving ring and 2 more bevel gears and I am getting the same outputs.

POWAAHHH!!!! this car rocks too bad there's no option for six stars

I rebuilt the gearbox out side the car. It does in fact have six gear ratios. I took two 40 tooth gears and put one on the input and one on the output, I then put a red axle in each of them to index them. I then turned the input gear once and counted the revolutions of the output gear. I came up with the following gear ratios. 1st-2.75:1, 2nd-1.75:1, 3rd-1.50:1, 4th-1.20:1, 5th-1.00:1, 6th and reverse-.75:1 to calculate the ratios I measured the number of degrees the output turned with one 360 degree rotation of the input. I then divided the output by 360. I also accounted for the fact that there is a "dead zone," in gearboxes like this because the drive rings have to turn just a bit to engage their respective gears. With 4 drive rings this can add up to about a 1/4 turn of the input with no movement of the output. To eliminated this I simply turned the input once before my calculation for each ratio.

Tyler, that isn't what I am talking about. It's the gearing underneath the driving rings that is not making it a 6 speed. The gearing underneath the engine has to change along with just adding another driving ring. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=247517 You are going to have gears on the same axle that are the same. Crowkillers has some pics here that should help you see what I mean. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=233924&n=47

You cant see it in the picture, but there is another set of gears on the drive ring. So it is actually a six speed

You know just by adding an extra driving ring doesn't make the transmission a 6 speed (I know this because I have tried and realized that it failed) If you test your gearing, you'll find out that it isn't truely a 6 speed at all. And LOL at the crowkiller comment. He has probably inspired more technic car builders than anyone in the game. I see his building techniques used quite frequently in many models from all over the world.

This is awesome. Great work on the transmission linkage, and especially impressed with the functional pedals!

This is incredible! Best chassis I've seen, I love the idea of making it "drivable" and not RC. Well done!

Awesome work, I'm so envied by your creations lol

this is absolutely amazing!!!! nice job

Cool I can't wait to see it finished. The chassis is awesome. A real working car with everything (clutch, throttle, brakes) Does it has a working handbrake? Keep building my friend ;).

very good work I like the clutch and the gaspedal. But the brake is not as good and in four wheel the front wheel to the front and the rear wheel back and erratic turns quickly.

greeeeeat...i`m waiting for more pictures...continue biulding... =D

this one is absolutely awesome!

Im an Avionics and electrical systems Technician on the MV-22 osprey, basically I fix anything with a wire

tyler love your stuff the jrod says keep buildin!your the best the crowkillers have nothin on this!!you rock the house!!do you fix stuff in the marines?you a mechanic?man you should be an engineer or something!!anywaw Id love us to be facebook friends!!making an account is simple you should do it!!go see my new dragin wagon!!any way email me!!see ya!!

If I was using bigger wheels I could make friction brakes using small tires. I also wanted to use the CV joints because it is actually powered and I don like breaking U-joints.

its actually AWD the power just goes to the wheels with the least resistance on them.

Awesome-y awsome-y awesome! I don't usually comment on WIPs but this is an exception. Most Technic models don't have working engine / gearbox / steering let alone the conrols to actually operate them! Now if only you can find a trained hamster... This looks like it will be engineering brilliance. Only flaw I can see is that the brakes will be very on/off (more like a handbrake) but I'm not sure there's a way round that. My favouriteproject on MOCpages right now - stunning work : ) No rating yet - but this will be a 10/10 when it's done

Incredible! This is properly awesome...

This is super! Yes you showed us that you built something different. There's also a guy that built a ferrari 1:12 scale model with exactly the same functions as the real car does. And even the engine (1:12), gearbox and yadayadayada...everything works like the real thing. Good to see someone manages to build one drivable chassis of Lego.

Very cool functions you made there. Brakes and clutches came to my mind once but never a gaspedal. very inovative.

amazing creation ,this car is cool the details engine and gear really awesome

Can't wait!!! This has to be the best Technic car EVER!

Sweet! This is shaping up to be your best creation ever!

That is amazing, It's so realistic, wow, you can even switch it from front to four wheel drive, really awesome, man, If you finish it I'd wish I was small enough to fit in it :p it's a great idea, keep it up

Very nice, I like the idea of becoming very very small and drive that car 8-)

You must be so clever to work all that out! brilliant work.

Goodness gracious! I never even thought that actual gear shifting with Lego parts was possible! Let alone most of the other stuffs this build has! Really fantastic job, to say the least.

HOLY POOP.

The motor is connected to the transmission input which in turn drive all four wheels

So the XL motor is connected to the rear wheels too, right? Now to find me a shrink-ray...

Now, you've got my attention- I love Audi R8's, and I know you will do a great job on it! Great start! Keep building! -Anthony Dunne

That's crazy! I can't believe you managed to shrink down all those features into a Lego model. Where's Rick Moranis when you need him... Can't wait to see the finished result! Peace ~ Packie
