RE: Better parts for Tornado S30
Many parts from HPI's less expensive lines like the Bullet or the discontinued Nitro MT2/RS4 have parts that are either identical or nearly identical. I've not found a way to cross reference these parts. It's always been a matter of someone posting where they have found replacement parts that fit from other manufactures. Often we'll read where someone has ordered parts from another company due to information from another member, only to read later that the parts didn't fit or work right. As far as finding replacement parts, eBay usually has a good selection of parts. Most of them are from "new tear downs" which works out good because a lot of the times the hardware is included. A good thing to do is lurk eBay and whenever you see parts for $3 - $5 with free shipping, order them and start building a backup box full of spare parts. Also, always remember when ordering a replacement part to order two, one for the repair and one for stock.
