You can live with that, but that's just inconvenience.

I reached out to someone in the UK that has posted positive comments on the AZ5 and has also posted a nice picture of his FC-100D pointed at zenith. I repeated your comments and he replied:
I found the AZ5 adequate for my own scope. The problem is that they are sent out from the factory without being properly adjusted, or at least that's how it seems to me. I had to adjust the tension of the worms on the gears to fine tune the mount to my liking, after which it worked pretty well in every position. I suppose if heavy eyepieces were used there might be a problem.
Another problem I initially had was that of squealing when turning the worms. I dismantled the mount and found the lubrication added in the factory, was missing the target. I reaplied the silicone grease and the problem was solved.
I found the AZ5 steady enough for my kind of observing as a grab and go mount, but its not as massive or as stable as the AZ4, which I prefer for stability at high power on a good tripod.
Of course the AZ4 doesn't have slow motion controls.
