Sometimes you'll find the wheels on our Edukit #3 kit can be a little tight when trying to fit to the motors. This can be down to ambient temperature or even just the very small tolerances in the manufacture of the wheels and motors.
If your wheels are taking some effort to fit, there's a couple of quick fixes that we found work well:
- Use a pen, screwdriver or similar object to open up the wheel hole a little.
- Use a tiny (a fraction of a drip!) amount of washing up liquid on the wheel hole to ease the fitting of the wheel to the motor.
