Does anyone know why their rockets are so inaccurate?

No guidance at all. Plus, unlike more modern artillery rockets, they don't spin for stability. In addition everything is made by hand. So tolerances stick. To cap it all off, it is unlikely that the grain(fuel) is perfectly symmetrical. It is a rectangular solid stuffed in a pipe, so it burns on 4 sides and likely not evenly.

That is why they have a CEP measured in kilometers. Even with inertial guidance, and you can get a module off of sparkfun.com for about $100, you can get a CEP of 100 meters or so. Access to a CNC mill could do wonders. As it is, they are restricted how they can be used. Unguided artillery rockets can be pretty useful if you fire them in a barrage. But the Pals can't do that. If they fire them too close together they run the risk of them hitting each other in flight. Even if they don't, the odds of them landing close together is low.

But, they are all they can build.
