This tank has ran great I got it until a week or so ago. The turret would stop turning at 1/4 to 1/2 rotation either direction. The clutch would start clicking and I had to move the turret by hand to get it to rotate. I took the top off to see if it was hitting something. I didn't see anything obvious, but I noticed the wiring wasn't routed very neat. I ran the wiring a little different, and it has worked fine since. I sent an email to support a week ago, and am still waiting for an answer. Thats why the 4 star rating.
