Now that looks like a hard-core chassis

Brilliant use of the piston elements You did a great job!

Soon, when the weather clears up.

You really hit the original spot on! I really like the top windows, they are unique.

The motor reminds me of one in the RC buggy motors?

Not bad, especially if you are limited by bricks. Keep on building and improving on yourself.

Great idea Sariel! Now I just need another micromotor.

Parts that fit in the car in real life, but not in LDD.

Here's the LXF file: blackcat.lxf

There are none ATM. For a challenge try figuring this one out imagine this like a teaser.

A little bit of crazyness I had yesterday:

Yes, there is quite a bit of friction in low gears, but that 8 tooth gears is for reverse only. So guys, wanna see something? David can sure be pursvaisive...

T-Tank, thats awesome! Thank you for praise guys

Thanks! Praise means a lot to me

I mean the full stud wide 20 tooth double bewel gear

Its really a great model. Do i see right, you also used motors to hold the axles together, like beams?

Really great engineering right there. About skipping gears, even in the new brackest the 20 tooth bewel gear can slip if there is too much torque. Thats why i usually use the fatter 20 tooth ones, as they have nowhere to slip.

Supply and Demand, David. If enoughy people demand, than I may make them.

I just counted them: 2 x 8 tooth gears 10 x 12 tooth bewel gears 5 x 12 tooth gears 14 x 16 tooth gears 8 x 16 tooth clutch gears 8 x 20 tooth gears 3 x 24 tooth gears 2 x knob gears 1 x old sytle diff gear 2 x new style diff gears So the total is 55 gears.

Nice mix of studless, studded and SNOT. Love the chromed wheels too.

So here's a stickerless version:

Well I guess thank to Paul you wont see any stickers for a long time About the 7+r gearbox. The first design had lots of friction because the low gears were powered from the top ones down, making a long chain of gears. So in order to make it more efficient the gears are powered from low ones with highest gear ratios and therefor friction to the top ones, which roll smoothest. Also thanks to 24 tooth gears I was able to pull off 12:20 gear ratio for odd gears and room for another 8 tooth gear for reverse gear.

This is you new idea? Why not make it as small as possible? You can fit a rear solid axle in a very small chassis and use the small front suspension like TLg uses in quads.

Thanks for thumbs up! For those who cant see the original version, there will be a muted version available here: http://www.youtube.com/watch?v=O42ZmfXBU4g

After a bit of teasing arround I managed to build an 8 speed transmission. So after making the tranny, I had to think of a car to use it. In my mind the car was a bit inspired by Lambo's look and a bit by Ford GT. Everything else was more or less improvized. So here's the first picture. I just dont have the heart to peel off the race truck stickers The rear opens up using two air springs to show off the massive V12 middle-to rear placed engine. Also the exhaust pipes are nicely visible. I was limited with the number of black panels, so the doors may seem a bit skinny. Each door uses a spring to help it lift up and lower. It also keeps it in end position. The crown of the car is the 7+R gearboy (A first that I know off) with next gear ratios: 1 1:3,472 2 1:2,778 3 1:2,083 4 1:1,667 5 1:1,25 6 1:1 7 1:0,75 R 1:2,25 These are possible thanks to 20 and 16 tooth gear combos. The way the power is delivered from all the four wheels is also complex. More or less everything is placed assimetrically to gain as much room as possible. Notice where the central differential is placed. And the fact, that the rear wheels due to being larger than front have a slightly different gear ratio. You may have noticed that the front diff is offset half a stud in front. This has two advantages. The steering rack is this way one the proper place. Also thanks to ackermann effect due to links, this allows the inner wheel to steer at a higher angle than usual, which translates to a higher steering angle. Another view of the gearbox. Notice the angled chassis connectors. These are at such an angle to make room for gears and to better support the floor. The rear of the car with its 4 exhausts and the spoiler: Another new thing in this car is the suspension. The springs are not directly attached to the upper links, but via the 3L half beam. The lower arm is connected to that half beam with a yellow 5L half beam. What this does is, that when the suspension is pushed upwards, the yellow links pull down the 3L half beams, therebye additionally pushing the springs. There are two benefits. Being a sportscar this lowers the suspension travel and hardenes the springs. It also makes the spring move in a more linear fashion. Another thing this car has is also an adjustable steering wheel, you can see that and more in the video:
