Remove the fuselage, wing panels, rudder assembly and stabilizer assembly from their bags. Inspect all items closely to
check for any damage. If any damage is found, contact the place where your SpaceWalker ARF was purchased, or Hobby
Services, to obtain a replacement for your damaged items.
The Great Planes SpaceWalker ARF is an excellent sport scale model. Because the SpaceWalker ARF is 1/4 scale it is
eligible for IMAA events. The IMAA (International Miniature Aircraft Association) is an organization that promotes
non-competitive flying of giant scale models.

Tele. (913) 823-5569
If you intend to fly the SpaceWalker ARF at IMAA events, it may be necessary to replace the 2-56 pushrods, clevises and
control horns with 4-40 pushrods, clevises and control horns designed for 1/4 scale airplanes. Although the plane flies
great with the hardware supplied, many events require the use of 4-40 style hardware. Also, all control surface related
servos must have at least 45 in.-oz. of torque in IMAA events.
