Hi , just an update I have put 2 sbricks in the red version of this car and they work really well , had a lot of fun in a car parking lot with the extra range about 30 meters with an Iphone 5s .

why 2 Sbricks?

why 2 Sbricks?

I did this so that each rc motor would have its own battery powering it.

ok

How does the differential lock affect the overall performance? I'm building my own version of this and I am wondering whether or not it's really worth it to get one of the red thingies for it.

Naaah, works fine even without :) turns better too

This is a really professional looking car. Than kyou for making the car and thanks to Zimix and Alasdair Ryan for the instructions. My son plans on raiding the lego and making it when he gets home from school.

cool ima post pictures once my last bricklink orders arrive

Hello, piterx!

I have some questions about RC for you Ford Fiesta.

1. How many RC units should I use?

2. Why both receivers must be on the same channel? if you plug motor to different receivers, but to the same color, they will rotate axe in the different directions, but they should not do this.

Motors are very expansive an I have only one receiver. So , I do not want to waste money. Please explain me how it must work please.

1. Do you talk about motors or something else ? This car only has RC motors, two of them.

2. They're on the same channel because then you only have to have one remote. And the reason why you have two receivers is because each motor has its own battery. If you plug your motors the same way (don't plug one at 90° of the other), they'll rotate in the same direction.

Has any one made an inventory of all the parts for this amazing  moc so that i can export them to bricklink xml? 

Just upload the brickstock file on 1st page, second link after instruction. to your bricklink wanted list. et voila..  

and have fun with it.
