Okay question guys I upgraded my bigrock to a 4s spur gear do I also need the 4s houseing for the gear? Seems to be hitting bottom of my gear case and rubbing on it. I also Installed three metal slipper pads am I supposed to have four? Any help it won't run right ever since putting this thing in. Replaced the whole chassis and the gear case from 3s. Anything else I should upgrade to 4s?
