Bloody Wonder made of coroplast

by dalaman | September 24, 2014 | (8) Posted in Projects

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.

Thanks. No video made. I lost my brand new möbius Monday during a flight (Velcro came unstuck to camera) and still am ticked off about it. I will buy another, sometime.

It's great to see folks experimenting! "Raw" coroplast can be sourced in many parts of the country so give it a try. A 2mm coro bloody wonder would be very light and still very strong.

After FliteFest I was thinking I'd like to do a coroplast bloody for combat but was worried the extra weight would be a problem... what motor did you use and did you hot glue or epoxy the build? I love the green and white ;-)

I used hot glue for all. The motor is an Emax 2215/20, 1200kv, 400 size weighing 2.2 oz. From Heads-up hobbies in Fl. You could also use the Suppo motor 2217/7 from Altitude Hobbies for the same performance.

Super cool! I've built a mid motor coroplast flat wing and it flys ok but when I tried to build one with the motor in front but no joy but it is sure is tough, 6 crashes 2 broken props and no visible damage I'll have to scale the sizes due to extra weight 18x24 coroplast =204 mg adams 20x30=114mg

Anyone have good tips for cutting coroplast? I've built a power pod using the stuff...very durable.But the durability makes it a challenge to cut with an x-acto knife.

I own a sign shop and we use corroplast extensively. We use a corro-claw ($20 on Amazon) for cutting along the flutes. This makes it easy to cut just one side of the flute to make a hinge. A box cutter and strait edge work the best for the other way.

they make a blade for a common box cutter that has a hooked blade called a shingle cutter that works very well for cutting along the flutes and for trimming but a heavy duty scissors also works for cross flutes.
