Turns out the left aileron servo had an intermittent issue where it would not move which caused the plane to be very difficult to fly. It is all fixed now and since then has had a massive 12 hour long flight!
This plane was a project completed by Washington State University's Palouse Aerospace Club. Check out our website for more information.
