BG725382321 Notso much a comment as help for someone looking at this car. I just got it, Jan 21. All drive shafts are super tight (almost pressed in) at the dog bones. I had to file off the bronze plating in order for the pins to slide in the cups. Both front/rear diffs are not shimmed properly, the front was super tight, click, click.....The other issue is that the diff housing is bowed in (at the output bearings, this causes interference between the housing and the diff cup. You need to shim the diff cup away from the housing, this also will fix the pinion/ring gear lash. The drive cups/shafts are loose at the diff support bearings, They can move inwards forcing the bevel drive gears into the spider gears, this locks up the internal diff motion. More shimming. The ESC does not have a programming function, you need a programming card. There is no amp rating stated anywhere on the ESC. The centre diff support is separate from motor mount, it is hard to set mash and keep the gears parallel. Thread lock is super strong, need to use heat to remove the screws. Also some was put on my C hub ball joint, it ate away the plastic and now I have lots of play on one side. It took me all day, $30 of shims, diff oil (the diffs were filled at 40%), I reinforced the back of the wheels with baking soda and super glue. Body was busted from shipping, the transmitter (Dumbors, this is a very good, simple radio)was just loosely bouncing around the box.Check out MrGridstrom vids before you purchase this rc. Keep in mind all these problem parts are used in the entire ZD line. I hope I helped someone, I found this info 1 hr too late. My review is also below, but I can't edit it.Now this becomes 3 star car, and I am being nice.
