Harmon Rocket III

John Harmonís 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
