The ProYo Stunt Pilot 3 in 1 (often abbreviated as the SP3) from Playmaxx was one of the first yo-yos developed specifically for offstring play, which at the time of its release was a relatively new style. The Stunt Pilot was famous for its aviation-inspired design, including spinning propellers with protruding rounded tips on the hubs, allowing it to act as a spin top when thrown horizontally. Similar in shape to the Turbo Bumble Bee GT, the Stunt Pilot was designed with a notch in the inside of the outer rim, allowing one to affix the end of the string into this notch in order to wind up the yo-yo for offstring or spin top play.
