OK Models Extra CT aerobatic plane

The airframe for the Extra CT was developed as an introductory scale aerobatic model for the smaller petrol engines that are now increasingly available. The Extra CT was designed in-house at OK Model and long-term repeat test flights were performed. The wing area, tail area, mounting angle and dihedral angle, evolved at the hands of some of the best pilots and designers in Japan. You simply cannot just scale down get the real machine and get a great flying model.

  • This product is a balsa/plywood, plastic film covered complete ARF machine. The completion of the model requires some work, such as installing the engine, and installing the radio control equipment. 
  • Covering film may sag or wrinkle with temperature changes. These can be removed by shrinking the film by applying heat with an iron for the model. 
  • The contents of the ARF model, design, colour, etc. are subject to change without notice.
