When I use the button for turning it just goes backwards. Why does this happen? I've checked the instructions and didn't find anything.

  • Thank you but I'm sorry I've didn't sad it correctly. It works once but when it goes forward it just ruins the wheel and then. It is not working. – Deatroyer Feb 3 at 13:45
  • What do you mean by "ruins the wheel" and "It is not working"? Could you please post images, videos or detailed descriptions of the encountered situation? – zovits Feb 3 at 13:48
  • I've „meant ruins the position of the wheel and it's tilt" so it can't turn. – Deatroyer Feb 3 at 15:35
  • I have updated my answer below, check if any of that helps. – zovits Feb 3 at 16:03

According to this article, the turning is supposed to function via a

wheel on the bottom that while the car moves forward stays straight but that once the car moves backward moves a little to the side and forces the car to turn.

If correctly built, it should look like this: enter image description here

A bit later the article offers a few tips on troubleshooting, among which there is your issue as well:

Problem: My Spik3r doesn’t turn

This looks like a construction problem. Check the above photo to see how the flying wheel is supposed to look like.


Edit after an update to the question

The wheel marked with the red free-hand circle is meant to slide freely in forward motion (the head of Spik3r is seen at the bottom of the picture), as it is pivoting around the axle with the yellow half-bushes, and get stuck in reverse (as the blue pin catches on the black undercarriage), thereby braking that side of the Spik3r and causing the model to turn towards that side.

If this wheel gets stuck during reverse, then it is working as intended and should provide enough friction to turn the whole model.

If it does not get stuck, then it is due to a mistake in the build.

If it gets stuck but does not force the model to turn, then you might need to change the friction between the wheel and the ground it's running on (e.g. use it on a carpet or any other surface rougher than the polished hardwood shown in the background).
