The past year I made two RC Rally cars. Both were great but didn't have enough speed for me, the solution?? Easy, make a smaller and lighter car.
This new XR7 car has 16 studs wide, 29 studs length and weighs only 550gr.
It has 2XL motors for drive and a M motor for steering with return-to-center.
The transmission is very simple to get the best possible efficiency. The final gear rato is 1:2.78, and max. speed is 4 kph (2.5mph)
To finish a little video:

very cool but you would have gotten a higher top speed with a Rc motor
You are right, but in a local competition we only could use PF motors...
Could you post more pictures of the steering?
This is great! All wheel drive is close to impossible in this size. Would you please post so,me more in depth photos of the front steering?
Please wait a few days, I will publish a pdf instructions step by step.
I don't know if you know the builder Jurgen or not but he has build a few rc cars as well an this one looks as is it may be better than his.
this is a beast! perfect design philosophy of light weight and simplicity = speed. on board footage is great!
Very nice. Waiting for the instructions. This is very inspiring!
There will be instructions?!!! YES!!!!!!!!!!
I am trying to reconstruct your vehicle but I do not have a few of the pieces you used. What is the part number for the piece that connects the two white wishbone pieces together? Also, what is the piece that is connected to the small PF motor? You used it to also connect the two large PF motors to the three gears?
Now you can the intructions step by step, and see it by yourself ;)
how do oyu get at the XL engine and at the recriver and at the batery box???
p.s. sorry but my english isn't that good
