Every FPV spec. One database.

Calculators

• Flight Time Calculator — Estimate quad flight time from battery capacity and average current draw.
• Thrust-to-Weight Calculator — Check the thrust-to-weight ratio of a build from motor thrust and all-up weight.
• KV to RPM Calculator — Convert motor KV and battery cells into RPM and prop tip speed.
• Battery Current Draw Checker — Check whether a LiPo's C-rating can safely deliver the current your setup pulls.
• AUW Builder — Add up component weights into dry weight and all-up weight for your build.
• LiPo Charge Cost Calculator — What charging your LiPo packs from storage actually costs per month.
• Betaflight & INAV CLI Diff Checker — Paste a Betaflight or INAV diff all and see which lines a release rejects - unknown, renamed or out-of-range settings - and which only restate the default.

Firmware settings

Every Betaflight and INAV CLI setting with its range, default and what each release changed (Betaflight 4.4 to 2026.6, INAV 8.0 to 9.1) - and a checker that tells you which lines of an old diff all a new release will reject. All firmware data.
