Great Planes® RV-4 .40 Size Sport Scale Airplane

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.

Easy interlocking balsa/ply construction, with built-in thrust angles and a wing that assembles flat on die-cut tabs.
Loaded with sport-scale realism—detailed cockpit features rollover bar, tandem instrument panels and a crystal-clear butyrate canopy.
Spacious radio compartment allows easy radio gear installation and quick fuel tank access.

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.

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.

A 2-piece ABS cowl, wheel pants, and wing tips are all supplied—as is the swept-back landing gear, made of 1/8" thick, heavy-duty duraluminum.

The wing features a fully symmetrical Selig 8036 airfoil, plus dual aileron servos for precision and authority. You can build the wing with or without flaps—the kit slows well for easy landings either way.

"The full-size RV-4 is known for its easy low-speed handling, excellent short-field capabilities, and almost effortless maneuverability—great qualities to have in an R/C model, too. And you'll find them in our .40-size version of the homebuilt favorite."
