PhaseDevkit phase — OA sensor phase CLOSED (MR82 forward radar stays); tree-gap (8 m) + payload tests passed; AUTO phase (tests 3–5) cleared by Zeynep, pending a clear Houston-area test site. Task board live (issues #248–#264, paid per task in ARROW)
NextCommercial: FAA returned the declaration asking for extras (incl. permanent Remote ID label) — Thomas sent everything back Sep 24; final approval = last gate before the store (plus CNC foam case inserts)
BlockerOA sign-off needs a test site · GPS EMI: Erick ordering spectrum analyzer + near-field probes; Julius replicating the dropout (T-13) · bounty applicants heavy on AI-generated submissions — Erick now vets via Discord + onboarding

PhaseFlying: first flight (Thomas piloted), yaw imbalance ~400–500 PWM → ~250 after stiffening; Sep 19–20 four flights incl. FIRST WITH WINGS. PT1.5 prep for transition (skins, wing servos, tail electronics, 2nd GPS) — transition attempts after the Germany meetup (~2 wks)
NextSep 25 decision: electric config = secondary Longshot in the gas-tank bay wired direct to the pusher (no swappable pusher hat). Erick designing PT2 boards (tail→main→battery, Pix32 FC); first PT2 likely electric; custom Longshot 14S3P pack targeted for Nov

PhasePhase 2 — PT1.5 design underway: welded steel inner frame → 60 mm carbon-tube sandwich with printed-aluminum end adapters (goal ~40 kg lighter), two DJI ag-tank bays as universal payload mounts, electronics unchanged
NextPT1.5 build aimed for November · KBM quoting CNC/PEEK folding connectors
BlockerPT1 first flight still gated on LBA authorization · centre landing-gear support + weight estimate to confirm

PhaseOn-chain settlement live on Base Sepolia (full-stack USDC E2E passed). FAA asked for additions (Remote ID label) — resubmitted Sep 24; final approval → ICAO serials + registration + real devkit sales
NextCheckout UI done (connect→approve→settle→receipt) · purchase-flow redesign in review (arrow-store #10, waterWang) · Dock V0 starting under Javelina Propeller Laboratory (RTK trough-landing gate; leg-contact charging, Longshot-compatible)
BlockerFAA final approval · transport-case foam inserts (waiting on CNC) · production DAO fee bounds undecided

LeadHex · Thomas
Phasev2 rebuilt for Openship + self-hosted Supabase (repo Arrow-air/flight-tracking) — three feedback rounds shipped Aug 12–13
Nextv2.3 live: .param download, aircraft-page durations, auth/admin/filters, param viewer, weather guard
BlockerAdoption gap vs Discord/wiki · unowned-record governance hole (JIS M-40) still open from v1

LeadJulius
PhasePT1 COMPLETE (Aug 29) — first custom 21700 pack (14S9P, 126 cells, BAK 65E) built; final weight locked 11.2 kg with ~2,540 Wh usable (+59% vs Tattu 4.0's ~1,596 Wh at ~same mass)
NextFull weight table + property comparison in longshot #26 (reopened for itemization convergence, ~364 g unaccounted: fuse/wiring/screws/sensors/clip/feet). Note: Longshot = standard Li-ion (58.8V full) vs Tattu LiHV (~60.9V) — chargers/docks must handle both. BMS v0 dummy → v1 STM32 smart next
BlockerNext pack: Spearhead custom 14S3P (~19.5 Ah, ~4 kg, AS150U) for Nov; BMS via contractor · cross-project (Spearhead→Longshot) payment has no precedent
