Pizza Box Flyer.
Just a sheet of coroplast with an engine on the front end and elevons on the back end with a rudder. All electronics are doublesided taped and cabletied to the top.
Got a GMS .32 with an APC 10X3 prop. Thing is sick to fly. Very squirrely at high speed but a total blast at low speeds. Does the most amazing harriers.
Going to add landing gear because I keep breaking props when I land. Have crashed it several times and only broke the prop.
