Overall a good tank. Plenty of detail including multiple part sheets to add to complete the look of the tank. Build quality is about average maybe slightly better than usual compared to my other 7 tanks.. Great improvement on the electronics and turret movement with the ability to turn I left or right at a range of speeds (proportional). Only drawback is the terrible battery life. On a full charge expect 5 minutes and no more. With the smoke machine and sounds that battery is going to be flat fast. Even without the smoke on and low volume don't expect to go anywhere far.. You can't upgrade the battery higher than 2800mah as the compartment deliberately forces you to keep to the same size supplied battery which mounts in the chassis horizontally from from track to track. Only let down of this model...
