Semi-scale model of a Czechoslovak aerobatic aircraft powered by a petrol engine 26 to 35 ccm. The fuselage of the model is a classic construction in a combination of balsa / light plywood, the engine cover is laminate. Easy access to the on-board electronics is ensured by the removable upper part of the fuselage; under the large bubble of the cabin cover you will find a nicely executed "Petr Jirmus".
