Hey all,
I just bought a brand new Ofna DM-1 1/7 scale RTR. After installing the wheels I set it on the ground to push around a little bit to make sure that the gears meshed properly(really just to play around with it). What I'm noticing is that when the front wheels are turned all the way to one direction and you push it, the front wheels "hop" , just like they would in a 4WD vehicle with locked differentials. They do this with all 4 wheels on the ground or just the two fronts. Do the diff's just need to be broken in? Or is it possible they were installed incorrectly from the factory?

Thanks,
Greg
