I have not had much time to put into the Outriders, but I have assembled the horses:
Those are the three basic horses included in the box. The one on the left is the leader's mount, and there are two each of the others.
These came together easily, but I am disappointed in the fit of the parts. There is a bit of a gap on the horse's neck on the left side from assembly, which I didn't notice until after I glued together the first one. I was able to solve that with a bit of extra glue on the following mounts. There is also a problem with the hindquarters. The two halves of the mini slope inwards at the join, although it really should not. Some of it will be covered up with the baggage pieces provided in the kit, but the rest went under the knife and file to smooth it out somewhat. Once painted they will be OK, I'm certain.
Here is a pic of all five:
Not a bad start.
