Eric Henderson was a good friend of mine. In his youth, he was an avid CL combat flyer in Scotland and various parts of England. He's participated in many forms of modeling, including his favorites of sail plane and slope soaring competition to RC pattern. His modeling led him to be an engineer/designer on Mr Popper's Penguins in 2011. (

He was the district 2 AMA associate VP. He has been writing model aviation columns longer than I've known him.
Eric passed away yesterday, 17 July 2016
