The Harmon Rocket I was a modified single place Van’s RV-3 sport plane while the Harmon Rocket II is a modified Van’s two place RV-4. Autos have been modified for decades by people seeking to make a vehicle meet their needs and desires and the Harmon Rocket is no different. Featuring a special airfoil twist, Hartzell’s propeller for the Harmon Rocket enhances cruise performance and adds irresistible ramp appeal.
