How aircraft flaps work

A whiteboard explanation of the theory behind lift and flaps in what is the first of a series that attempts to explain the science behind the technology we use in our RC planes. I’ve tentatively called this series “Theory Thursday“ but it might also be Technical Tuesday or Whiteboard Wednesday -- you tell me :-) And if you’ve got ideas for new theory videos, mention them in the comments below. Also, if you have any questions about this video, ask-away and I’ll do my best to answer them.
