I am extremely new to rc. I purchased what he said, was an ax10 scorpion artr. I am having 2 issues. The first one, is one of the rear wheels will not pull under stress. The other, is it will take spells and stop moving forward or reverse, but will still steer. If I let off the trigger and press it again, it will move another 3 feet or so and stop like you let off the trigger. I did try to rebind with no change. Any help is appreciated.
