Air Craft's Post is an offline‑first technical logbook for RC aircraft and drones — a structured hangar, pre‑flight checklist, flight log, and parts supplier notebook, all styled like aircraft documentation. Register your active aircraft with a photo, weight, type (quadcopter, airplane, helicopter), and notes, then run a five‑item pre‑flight checklist for each flight; skip an item three times and it turns red with a warning, but when everything is checked, a propeller animation plays and "READY TO FLY" appears. Log every flight with duration (0–60 minutes), crash status, damage description, location, and notes, and watch statistics grow (all‑time flights, crashes, average duration, last 30 days). Save your favorite supplier stores by category (batteries, propellers, motors, frames) with URLs and addresses, and export flights or store lists to CSV. No price comparison, no live telemetry — just a quiet, blueprint‑blue hangar for your flying memories.
