That works fine for an office build. But RC cars don't work well in raftered house ceilings. Most houses here use 2x6s or 2x8s for rafters. Or at least most of the ones that I've seen. If you're running network lines down the same conduit as electrical wiring you're violating about a dozen fire and safety codes. Not to mention every basic rule of network wiring that there is. Electrical wiring, ESPECIALLY two-phase and three-phase wiring emit large amounts of RF. RF kills data integrity. One of the most basic rules of network wiring is NEVER string your network wires across power conduits, junction boxes, or lighting fixtures. Don't believe me? Ask anyone that does it for a living. You, physically, can do it, but you shouldn't. You're asking for trouble. --- Bruce Bruen <bbruen at bigpond.com> wrote: > Try a $50 remote control 4WD model (ATV?
