[FAIL] Mini Fast car

[Technic Jim]

This car was a quick build (no pun intended ) that would follow in the footsteps of my first car with RC motors (http://www.eurobricks.com/forum/index.php?showtopic=124143#entry2503279). It is powered by 1 RC motor geared down 1.4:1 and has a theoretical top speed of ~11kph. It would have all worked fine had the car not been so top heavy and had a tight steering lock. The result was that the car couldn't steer without flipping over and was almost impossible to control because I made the mistake of putting gears on the servo's output so neutral position on the motor wasn't dead straight with the front wheels. It also didn't help that today was very sunny so the IR control kept on getting interference! There is a short video I made though:

This car itself was a failure, but I think my next step will be to use a minizip and change the servo positioning. I can't post any pictures today, but I will soon and an LDD file may present itself as well.

Thanks for reading and please leave any feedback, Jim

One thing could save this car: the "train"-type RC controller. It has gradable controls, so delicate steering instead of "LEFT-CENTRE-RIGHT" setup would be possible.

Now why didn't I try that!

No worries, I learned about it a couple days ago, too, from Sariel's Volvo review. ;)

So, as promised, here are the pictures:

More pictures are available at my Brickshelf account: http://www.brickshel...i?m=Technic-Jim

There is also an LDD file, which is attached to this post. Edit: It turns out I can't attach the file, so it is on my Brickshelf. Does anyone know why I can't attach it? It just says: Error This upload failed. Thanks, Jim

Could you move the servo or the rack to in front of the wheels? You could then sink the battery box lower into the chassis.

I don't know why your model is "top-heavy", my Aspire had the battery higher than your chassi and never tipped over.Put stops on steering (another 2l thin liftarm)

About the error, you could have run out of max space for attachments. Better use Bricksafe, instant upload and no approval waits

There wasn't really much room, but I suppose I could have.

It wasn't a big file (roughly 20kb) but I will look into using bricksafe.

Just checking! My Bricksafe account can be found at http://bricksafe.com/pages/Technic_Jim/ . Cheers for the heads up LXF. Now for the next challenge, how do I use the images I have uploaded on Bricksafe and embed them in Eurobricks. If anyone could tell me, that would be great.

Cheers, Jim

Go to MY PAGES, select the pic you want and open it. Once it's opened, click "Copy Image URL" or "copy image address" or something along these lines, than come here, click the "Image" button (under the "Smiley" button) and paste the copied URL Repeat with other pics.

If you want to share the instructions direcly, copy the URL of the lxf file by right clicking on the download icon that appears once you hover your mouse over the lxf and selecting "copy the link URL" (or somesuch) and paste it here.
