Frequently Asked Questions

SpinWing Vanes use a patented curved or hooked profile that traps and compresses air to spin the arrow up to two times faster than a standard vane. This rapid rotation stabilizes the arrow more quickly, resulting in tighter groups and greater resistance to wind drift — particularly important at longer distances.

SpinWing Vanes are compatible with recurve bows, compound bows, and crossbows. They have been tested at speeds over 350 feet per second without adverse effects, making them suitable for even the highest-performance modern bow setups.

Original SpinWing: Features a curved pocket design with minimal drag — ideal for archers prioritizing speed and tight groups.

Elite SpinWing: Adds a rear sloping hook for faster initial stabilization — excellent for competition shooting where quick arrow recovery is critical.

Hunter SpinWing: Features a larger hook and body for maximum stabilization and retained kinetic energy at distance. Popular with bowhunters and 3-D shooters who need consistent accuracy with heavy arrows.

Vane size selection depends on your arrow weight, bow draw weight, and shooting discipline. In general, lighter arrows and indoor/short-distance shooting benefit from smaller vanes (1 9/16" to 1 3/4"), while heavier hunting arrows and outdoor/long-range shooting benefit from larger vanes (2 13/16" to 5"). Contact us if you need a personalized recommendation.

All SpinWing Vane models are available in eight colors: Red, White, Blue, Yellow, Black, Green, Pink, and Orange.

Yes. SpinWing Vanes have been tested at speeds exceeding 350 feet per second without adverse effects. They are well-suited to modern high-performance compound bows.

The Formaster is a training aid that attaches to the archer's draw arm to teach proper back tension and follow-through. It works by providing resistance at the correct stage of the draw, helping to establish the muscle memory needed for a consistent, repeatable release. It is equally effective for beginners building foundational habits and experienced archers refining technique.

Original Formaster: Uses a rubber resistance cord that allows you to train with a full arrow release. The strap and resistance cord are sold separately, allowing customization for your draw length and body size.

Rigid Formaster: Uses a non-rubberized cord and is sold fully assembled. It allows you to draw and release without using an arrow, making it ideal for indoor dry-fire training sessions.

Measure the full circumference around your elbow with your draw arm completely straight. Take the measurement at the largest part of the elbow. The strap should fit snugly when your arm is bent at full draw. If the strap is too large, it will slide down the arm and reduce the cord's effectiveness.

Sizes range from X-Small (8"–9") to XX-Large (13"–14").

General recommendations:

• J.O.A.D. & beginners: 13–17 lbs (short draw lengths ~18"–20")
• Women & young adults: 21–28 lbs (medium draw lengths ~21"–27")
• Men / longer draw lengths: 28–31 lbs (28" or longer)

The maximum recommended pull-weight without an arrow is 50 lbs; with an arrow, 70 lbs.

Yes. The Formaster Training Aid is designed to install on any bow. The technical manual included with every purchase provides step-by-step installation instructions. The bow is not included.
