Selkirk Luxx Control Tungsten Tape Calculator
16.4" x 7.5" Invikta · 20mm X7 Thikset Honeycomb. Stock static weight is 225 g (7.94 oz). Balance is 23.6 cm from the butt cap. Swingweight is 113.0 kg*cm2 about the 10 cm pivot. Twistweight is 6.35 kg*cm2 about the centerline. Face length 41.66 cm, width 19.05 cm.
Selkirk Luxx Control is a solid-core pickleball paddle (honeycomb or foam, no strings). Adding grams at the throat or belly stabilizes off-center hits by raising twistweight. Adding grams at the tip makes the head heavier to swing. Read the live deltas before you cut tape: a higher swingweight is more plow on drives and slower hands at the kitchen line.
Volt marks are zones with tape on. The dashed line is the 10 cm swingweight pivot. Honeycomb dots mark the solid core.
Where the strips sit on this Selkirk Luxx Control
Coordinates come from the CourtHz preset: yi is centimeters from the butt cap, xi is centimeters from the long centerline. The tip coordinate is not zero, so a 12 o'clock strip still adds a small twistweight term along with the large swingweight term.
| Zone | Strips | From butt cap (cm) | From centerline (cm) | What the mass does |
|---|---|---|---|---|
| Throat (5 & 7) | 2 | 22.4 | 8.1 | Boosts Twistweight & keeps balance maneuverable with minimal Swingweight penalty. |
| Belly (3 & 9) | 2 | 30.2 | 9.525 | Maximum lateral Twistweight expansion across the primary sweet spot. |
| Upper Corners (10 & 2) | 2 | 37.4 | 8.9 | High plow-through + upper-face stability for heavy drives and blocks. |
| Tip (12) | 1 | 41.3 | 2.2 | Maximum Swingweight & head-heavy drive power at 12 o clock. |
Parallel-axis formulas
Static weight, grams and ounces: M = M0 + the sum of strip masses. Ounces use 28.3495231 g per oz.
Balance point, centimeters from the butt cap: B = (M0 * B0 + the sum of mi * yi) / M.
Swingweight, kg*cm2 about the 10.0 cm pivot: SW = SW0 + the sum of (mi / 1000) * (yi - 10.0)^2.
Twistweight, kg*cm2 about the longitudinal centerline: TW = TW0 + the sum of (mi / 1000) * xi^2.
Symmetric zones (5 & 7, 3 & 9, 10 & 2) place two strips of the gram weight you pick. The tip (12) places one strip. Each strip is limited to 1g through 6g.
