        Harmon’s conversion kit for the RV-4 is the ultimate aviation experience 
        for recreation and sport flying. From winning awards at Oshkosh to EAA 
        fly-ins and air shows this aircraft should be the choice for RV builders 
        of kit plane plans or individuals interested in avionics for homebuilt 
        aircraft. The HR2 is not a quick build kit as many builders of the Rocket 
        prefer to be more involved in the aircraft building process and express 
        a preference of some minor fitting and trimming. If you are looking for 
        a home built experimental aircraft consider the flexibility and 
        performance of the Harmon Rocket
