I made a Bloody Wonder useing a sign I got for free made of coroplast. I used the same techiques as for foam in building it. The material is twice as heavy as $tree foam but is highly durable in a crash. I had to use a 400 size motor to fly this thing and it flys great. It's fast and agile for war games or just acting crazy at the field. The plane is made as per Flitetest plans with the exception of the "hinged bottom" fuse. I pinned it in the front with a BBQ skewer so it would rotate. Inside the lid houses the 2200mah battery with alarm. On the fuse's inside I have the esc mounted with velcro. The receiver sits in the back. I secured the hinged bottom with a BBQ skewer as normally done with the power pod speaking of, I didn't use. Instead I glued a permanet motor mount on using extra foam on the inside for more support. The hinged bottom overlaps the sides of the fuse. See below the pix for a few details. I made this a few months ago and didn't take any photos or videos of the construction, sorry.
Oh, I have the throws set pretty tame at 50% with 50% expo and it is still touchy. At 100% you better be a pretty good pilot or have a death wish for your BW. With a 10x5 prop it really cranks.
