can anyone tell me what the correct wheel nut size is for the tc4 rtr. im hearing 8/32. but with that nut you need a 3/8 nut driver. i know for sure that my tc4 does now have a 8/32 nut cuz im using a 5.5 mm or 11/32 nut driver nut driver, which is smaller than a 3/8 nut driver. so if someone can clarify what nut it is that will be great cuz i dont want to buy a wrong set.
