So, I'm going to be purchasing an ARRMA Outcast 4S V2 when spring rolls around and the golf course opens back up (I'm on maintenance team, so there's no work over the winter other than fixing engines). I would like to have a good list of metal parts ready for it when I inevitably break something. However, I currently cannot find any aftermarket parts for it on major aftermarket retailers. There's plenty for the 8S, but I can't find any for the 4S. Any good suggestions?
