Very poorly manufactured chasis. The motor clamps that needs to be inserted into tnhe slots provided on the chasis jist do not go in. The slots are much narrower than the thichness of the motor clamps. The cuts made for the slot are NOT smooth at all and are hightly serrated. I hid a dead end in the first step of the assembly itself. I wanted to give 1 star but looks like the behind the screen but somehow system accept/save it in my last attempt.
