This is a Marcoux-Bromberg R-3, it's bright yellow and quite pretty for a plane. I'll admit I don't know much about plane engines, except that they make the plane fly, without the engine it would be a glider. Do you know how hard it is to find people that will run straight while tossing the plane like the paper ones they has a child - it's pretty tough.
