HM 34" EPP Pitts Special S1

Meet the Pitts Special S1! The 34-inch Hacker Models Pitts Special S1 combines the unmistakable appearance of a classic aerobatic biplane with the durability and easy handling of lightweight EPP construction.

Its fully airfoiled wings provide a more solid and traditional feel than a flat-foam model, while the generous control surfaces allow smooth sport aerobatics and capable 3D performance. Detailed printed graphics and the compact biplane profile help the Pitts stand out both on the ground and in the air.

The Pitts Special can be assembled in an evening and is well suited for pilots looking for a durable everyday aerobatic model with classic styling, predictable low-speed handling, and plenty of control authority.
