Safety factor vs max speed

Uses the NACA thin-panel flutter boundary. Real flutter onset depends on construction quality, adhesive joints, fin alignment, and surface finish. Add a safety factor of at least 1.5×. Thicker fins, shorter span, and stiffer materials all increase flutter resistance.

V_flutter = a × √( G × (t/c)³ / (1.337 × AR³ × P × (λ+1)/2) ) Ref: NACA TN-4197
