Great Planes 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.
Features:
Easy interlocking balsa and plywood construction, with built-in thrust angles and a wing that assembles flat on die-cut tabs.
Wings are one-piece, all wood
