They are very well designed and engineered, and clip together without glue. I will use some though, for added strength. They look and are much more solid than the flimsy and brittle HaT ones. They also snap together in seconds. I clipped the parts off the sprue and had a quick test run, and there are no problems at all. I only bothered to trim the excess sprue from the chariot hull in order to ensure the pins fitted, but I will finish the rest later and make a start on it. Unlike the HaT plastic, this stuff is easy to cut with a sharp blade, and does not tear.
I mentioned in my last post that the set does not include a driver. I was going by reports from the excellent Plastic Solider Review site. However, I think they are incorrect. One of the figures is clearly, to me at least, in a characteristic pose for a chariot driver. All one needs to do is remove the pin on his arm, and I wonder if that was the intention. It would also not be hard to convert the figure holding a sword to a driver, at a pinch. I'm actually at a loss as to why he would be using that weapon on a chariot anyway.
So lesson learned. If building a chariot-based army again, I will think long and hard before using HaT chariot models. I dare say not all the HaT chariots are as badly engineered as their Assyrian one, but I'll make sure to check them out first.
