I've also heard that it is the impact of ascending angels on the lower
surface of the airframe, but they take breaks sometimes to pray, usually
along with the pilot :-)

A similar theory about how competition free flight model aircraft was
around several years ago, only instead of demons, its creatures were
small, fat, furry Bernoulli Balls. Like the demons, these hold onto
models wings to support them when they are flying and won't go near a
really ugly model.

However, they are also responsible for thermals, which occur when crowds
of Bernoulli Balls dance around because they are warm, happy and excited.
Models that enter a thermal are grabbed and included in the dance. This
also explains why there are no thermals at night - the BBs are all
sitting on the ground, worn out by their day's activities.
