A main shaft slide sleeve assembly for remote control helicopter includes a slide sleeve fixedly connected to a main shaft of the helicopter; a spherical hub disposed in the slide sleeve to connect to a swash plate via two hub links, and to two flybar rods via two projected columns; a main blade central hub horizontally held in the slide sleeve to connect at two ends to two main blade holders; and two washout control levers pivotally turnably connected at respective middle section, outer end, and inner end to the two main blade holders, the flybar rods via two first link, and the swash plate via two second links. Thus, the swash plate may control deflection angles of two flybar paddles on the two flybar rods and two main blades on the main blade holders via the hub links and the second links.
