The Kastaplast Rask is a 14-speed very overstable distance driver. With published flight numbers of 14 / 3 / 0 / 4, it is most often described as suited for headwind drives that have to hold their finish, hyzer bombs off the tee.

Overview

The Kastaplast Rask is a 14-speed distance driver rated 14/3/0/4.[1] Its defining trait is that it is less than 22 mm wide at the rim — Kastaplast's own copy argues the Rask "proves that a disc's speed cannot be determined by looking at the width of the rim," and pitches it at players who want the fastest disc available without the widest rim.[1] The company is candid that it is a polarising mold: "Some players swear by it, but it sure isn't for everyone."[1] Rask is Swedish for "fast."[1] PDGA specifications: 21.2 cm diameter, 1.6 cm height, 1.1 cm rim depth, 2.2 cm rim thickness, and a 176.0 g maximum weight.[2]

Flight numbers describe the published behavior of the disc when thrown at its design speed. Real-world flight varies with plastic, weight, age, and thrower power. The community-averaged numbers above reflect crowd-sourced observations from real throws — typically slightly more understable than the manufacturer's published values, which is the most consistent pattern across nearly every commercial mold.

Kastaplast lists the Rask as suitable for advanced players, headwind shots, hyzer bombs and getting out of trouble.[1] The combination of speed 14 with only 3 glide and 4 fade makes it a finish-first driver rather than a distance-maximising one: it needs real arm speed to reach its speed rating, and at anything less it simply fades out early. The narrow rim is what distinguishes it from other 14-speeds — players who cannot comfortably grip a 2.4 cm rim can still throw this one.[1]

Best for:

  • Headwind drives that have to hold their finish
  • Hyzer bombs off the tee
  • Utility shots to get out of trouble
  • Overstable forehands for high-arm-speed players

Plastics & variants

The Rask is available in the following plastic blends from Kastaplast:[1]

K1

Plastic blend significantly affects flight character. Premium plastics like Champion, Z, or C-Line generally fly more overstable when fresh and hold their stability over time. Base plastics like DX, Pro, or Active beat in faster and become more understable workhorses with use.

History

The Rask was Kastaplast's debut mold and its first PDGA approval, certified on July 18, 2013 and announced by the PDGA's Chuck Kennedy with the Swedish company introduced as a "new manufacturer."[3] Kastaplast's own launch statement described it as "a concept disc — a new take on aerodynamics," the product of two years of sketching, 3D printing, manual sculpting, aerodynamic simulations and field testing, and credited its speed to "its innovative drag reducing ridge at the bottom side of the flight plate."[3] The mold was retooled within months: a second certification, filed as "Rask (new)," was approved on January 12, 2014 under cert 14-05, and those are the dimensions carried here.[2] Notably, Kastaplast's 2013 launch copy characterised the flight as simply "Stable" — the current official rating of 14/3/0/4 is considerably more overstable.[1][3] The Rask remains in the Kastaplast distance driver lineup and is offered only in K1.[1]
