Heng long has released they version of Abrams and its about to hit north american market. From a toy grade company,Heng long is progressively growing into hobby grade with each and every new release.The plastic work on molds almost as good as Tamiya and in my opinion better then Revel. Electronics are still primitive,but few more years and they'll catch up. I have several Heng long tanks and have replaced the sound boards with SLU. The other thing is: The tanks are coming RTR,but if you like to super detail,optional parts are included.
