RV-4 40 Sport Kit

RV-4 40 Sport Kit

The homebuilt “hot rod” as a smooth-flying .40!


While not specifically intended as a vehicle for showy aerobatics, the popular, full-size RV-4 has proven very capable of them all the same. Great Planes’ RV-4 model offers similar versatility. Ideal for intermediate-level aerobatics, it offers good knife-edge capabilities, tracks beautifully, delivers almost unlimited vertical performance with a .46 engine...and is also a great choice for just having some “Sunday” fun.
  • A straightforward building project with no retracts to add complexity, the RV-4 goes together easily thanks to precisely interlocking wood parts and detailed, photo-illustrated instructions.
  • Generous package of Great Planes hardware includes rod-in-tube pushrods for smooth control surface operation.
  • Reinforced nylon Adjustable Engine Mount perfectly fits any 2- or 4-stroke engine within the recommended range.
  • Loaded with sport-scale realism — detailed cockpit features rollover bar, tandem instrument panels and a crystal-clear butyrate canopy.
