So like the title says it's not trucks/construction equipment but like most I am into other r/c toys as well. American Hero's channel is currently running a series called military Collectors and just did a 2 part episode on the AAF tank museum in Danville VA. Part 2 also includes a segement on the r/c tank battlefield that I participate in a couple times a year. Hope you enjoy the episodes.
