This is my scratch built 52% Extra 300 SP that weighs 48.5 lbs. with a DA 200cc, it has a 150" wing span and a 144" fuse length. It is completely constructed using CA on all wood parts and Gorilla glue for sheeting on foam parts only. This is a video that a guy was doing at a big bird event a couple of months ago.
