    It depends what you are looking for. For max efficiency ball bearings and Teflon with oil for lube. But flex and bearings need cleaning out and re-oiling after every run, and bearings will need replacing periodically. For ease of maintenance no Teflon and a floating bushing will last nearly forever, and the shaft just needs cleaning an re-greasing every few runs or at the end of the day.

    Alternatively wire drives are the bomb as long as you don't have a tight bend.

        Don't use regular WD40 as a lubricant, it isn't one (though it does have some minor lubricating properties). Having said that I use WD40 branded PTFE loaded lubricant as i find the smart straw system convenient, but sewing machine or 3in1 work fine too. I haven't tried gun oil but from what i remember it is stinky stuff and probably more about corrosion resistance than lubrication.

              It is a high RPM bearing oil, I use it on all my motor bearings.
              So why not use it on Ball Bering's in a strut.
