Thrustline Rocket Toolkit is a fully offline design and stability companion built for model rocketry hobbyists — from Estes starter kits to high-power NAR/TRA builds. No live data feeds, no sensors, no gimmicks: just real physics you can trust before every launch. Enter your airframe dimensions, fin geometry, and nose cone type to get an instant Barrowman-equation Center of Pressure calculation. Add component masses and positions to compute your Center of Gravity, then see a clear, color-coded stability diagram in calibers so you know at a glance if your rocket is stable, marginal, or unstable. Predict performance with a numeric drag-based altitude and velocity simulator, using your rocket's mass, motor impulse, and frontal area to chart altitude, velocity, and time-to-apogee. Browse a bundled offline motor reference library spanning A through O impulse classes with thrust-curve charts, or add your own custom motor data. Keep your build organized with a parts and inventory tracker for tubes, fins, nose cones, motors, parachutes, and wadding, complete with low-stock reminders. Attach build photos and notes to each rocket, and update weigh-ins to automatically refresh your stability calculation. Before heading to the pad, run a customizable NAR/TRA-style pre-flight safety checklist covering igniter, recovery, and range-safety steps. Then export a clean, shareable one-page PDF flight card summarizing your design specs, stability margin, and predicted altitude for your range safety officer. Thrustline Rocket Toolkit works entirely offline, with no account, no subscription gimmicks, and no network dependency — just a dependable engineering tool for hobbyists who care about doing it right.
