Also released was an optional "Barnstormer" attachment that allowed the user to extend the propeller heads even further than what the standard propeller caps allowed. Unlike the Turbo Bumble Bee GT, the SP3 used a thinner variety of Brake Pads. These were half the thickness of the standard pads, and did not last nearly as long, causing string slippage issues when worn out from extensive use. The later release of the Stunt Pilot featured O-rings under the spacers to create a twist-adjustable string gap.
The Stunt Pilot was made of a durable plastic branded "ProYonium," allowing it to take more punishment without breaking (this was necessary for offstring play). ProYonium was advertised as an incredible, space-age memory-healing plastic. The first Stunt Pilot prototype, made in March 1998, was originally made of plastic, but Playmaxx figured out right away that it wasn't durable enough for the rigors of offstring play. This lead to the implementation of ProYonium in the finalized production model, after a test run of Albino Bee GTs that used the material in its natural color. In recent years, it was revealed that ProYonium is in fact, a variety of Celcon. In a famous test, a Stunt Pilot yo-yo was shot using a .45 caliber Winchester lever-action rifle from a distance of 15 feet. Though the projectile had passed through the plastic with ease, it was shown that the bullet hole had "healed" over time.
Duncan did not continue to produce the Stunt Pilot after buying out Playmaxx. Although, at one point in 2007, Duncan distributed a new-old stock (NOS) of Stunt Pilot yo-yos, which sat in a warehouse somewhere for a long time.
