CONSTRUCT & CREATE Salt Water Fuel Cell Engine Car DIY STEM Build Your Own Kit

Q: How well do they fit together, do they actually work?

The tires on my model didn't fit, it's like they were a millimetre too short. I figured I'd build it without the tires, at which point I discovered that the blue wheel assemblies didn't click into anywhere, and they simply hang on the axle. The reason this is a problem: Tilt the model to install the other two wheels, and the first two will fall off. In fact, tilt the model at all and the wheels will gleefully fall off. I don't see how that's supposed to work at all.

Q: Are the instructions easy to follow?

My 11 year old grandson managed to follow instructions and build with minimum help, He loved it .

Q: Where can we buy more magnesium plates from for the battery?

I’ve no idea have you tried Amazon or eBay?

Q: What is the motor voltage?

I don’t know, never got ours going .
