Make sure your baby powder is actually talc. Much of it is now corn starch based, which seems to work fine for changing diapers. That might come in handy in a few years, speaking personally. However, DO NOT use non-talc powder on your tires and tubes. The corn-based stuff absorbs moisture and gets clumpy over time. So you can end up with small hard nodules of corn starch that can grind away at or even puncture your inner tubes months or years down the road. And make sure you use lots of extra real talc if you use Aero Classic (Desser) Leak Guard tubes made from Butyl. The mold lines on those tubes are very susceptible to tear out in the presence of corn starch, especially at low air pressures where there is movement between the tube and tire surface. The Michelin Air Stop Butyl tubes don't seem to have this kind of problem. But talc 'em all.
Old-fashioned talc products = yes
Non-talc baby powder = no
(and a few more airplanes)
