"you need a backup system - just in case your nifty micro controlled wonder
goes south!"
If your exhaust port aims straight up, simply fly a little thin-paper 'kite'
tethered by three threads above it. Since it moves around, your eye will
instantly notice if it should crash due to lack of air flow. So basic it
can't fail -- remember, "simplicity is ingenuity".
