After the destruction of the short lived Fronkensteen 3, I am ready to do it again. Presenting the Fronkensteen 4. The parts were mostly collected from the vendors at the King Orange Internationals. The wing is supposed to be from a Super Chipmunk, the Fuselage is from an ARF Cardinal. The tail group is unknown. It could be called the KOIsteen, but that might be a little too weird, even for me. All remaining parts will either be scrounged or improvised.
