I am building the Trouble Maker from Eureka and I find it is wide enough for a OS or Magnum 91 four stroke. At least that is what I am putting into mine when finished. I am posting pictures of my progress to date. The wings still get an 1 1/2 inch side plate on them so I am not finished whti the wings as yet. I did not fully sheet the wings as the plans call for because I am trying to lighten the plane somewhat. Any ideas or comments are appreciated. I intend to fly the plane in SPA competition. Check the SPA website for planes that qualify for competition and for places to purchase the kits. World Models is making an ARF called the Intruder that is SPA legal and even carries the logo on the plane.
