OTOP

[Ed Alt]

Completely normal. We call it the Pterodactyl screech at our field.  It will do it in ordinary roll at high deflections too, it's just the air getting in the gap of the up aileron.

  I test flew the OTOP today and when I entered any kind of snap roll the airplane made a real high pitch squeal. It only does it in the snap roll. Someone at the field said that they have heard of the composite airplanes doing that because of the hollow ailerons. That didn't seem to make sense to me so I thought I'd pose it to everyone to see if they have had this before in a composite airplane.
