Thanks toughbeard... What about the front and rear diffs... The kit came with a separate updated page that asked for 3mm of spacers for front and rear diffs but kit only supplied 2mm ... Assembled the front and rear diff and they feel like the center diff.. Once assembled each outdrive has about 1mm of play... I ordered more shims just in case ... obviously want to avoid stripped gears as much as possible, but I'm not sure how much play is too much...I'm new to this buggy and still learning rc, just started in August... Thanks for your help
