I built this using some of my Technic parts.

About this creation

This weekend I have been experimenting with my Technic parts. I hadn't ever built much out of them before, but since I have recently sorted my LEGO pieces by type of piece, I thought that I'd build some things from them. I didn't really know where to start so I just decided to build a car. I used my wind up motor from one of my old LEGO Racers sets to power it and I connected the back axle to the front axle using some of my large and small bevel gears from my Bionicle sets. I would have made the car longer but the motor wasn't powerful enough to power all of the gears between the back axle and the front axle. This was the longest it would be with that function still working. I am happy with the result even though it is really simple.

I also built a working roller coaster hill today out of Technic parts. It can be seen here.

Nice but what I think he is saying about the wheels being different sizes is that if the front and rear are geared together without gearing up or down, they all turn at the same speed. Since the larger rear wheel moves farther on one turn, it is pushing on the front wheel which takes a shorter distance on one turn. This increases friction between the tires and the ground. It probably will go farther on all the same type of tire.

Quoting John Daniels

Quoting Kayla Rhodes It goes pretty fast (faster than it would with only the back wheels being powered by the motor) and it travels about 6-7ft before stopping. The motor is 9 years old so it does not work as well as it could but it is my only big wind up motor (the other one is 11 years old and barely works anymore for some reason).

Cool, That's a a pretty good distance for a wind-up motor! It might be dirt. Do you have any problems from the different sized front and rear wheels?

Nope, they work fine. I was using different wheels, but these wheels are newer than the ones I was using so they have better grip.

Quoting John Daniels Looks functional! How fast would you say it goes and how far? --John
