If you want an empirical demonstration of what I'm saying, get yourself a cooling fan and a matchstick. The fan will simulate the slipstream of the propeller and the matchstick will be your puff of smoke.. light the matchstick, put it in the slipstream of the fan and see how long the smoke lingers..
