AI flight report
This was a 5-minute-8-second flight covering 6,592 m, flown entirely in MODE_10 in light drizzle with a 29.5°C ambient temperature and a modest 2.84 m/s breeze from the SSW — none of which appears to have been a limiting factor. The aircraft climbed quickly after a 0:12 takeoff, reaching cruise altitude near 40 m by 0:30 and holding roughly 37–43 m above home for the rest of the flight, topping out at the recorded max altitude of 45 m at 1:20. Speed was brisk throughout, averaging 21.8 m/s with a peak of 33.8 m/s at 2:01, and the drone ranged out to 366 m from home by 4:07 before returning and descending back through 15.8 m by 5:00, ending in what the log flags as a descent phase reaching -6.2 m/s at 5:01.
The standout pattern in this flight is motor 4. At 0:00, before the aircraft was even airborne, the log shows a 770 µs asymmetry between motor 3 and motor 4, and by 0:08–0:09 motor 4 was already pinned near saturation (1942 µs, peaking at 2200 µs at 0:09 with a 916 µs spread across motors — versus an ESC ceiling around 2000 µs). That same motor saturated repeatedly across the flight — 0:48, 1:21, 1:56, 2:46, and 4:37 — each time in the 1900–1922 µs range, and a smaller but still notable 201 µs imbalance between motor 1 and motor 4 reappeared right at the end, 4:58. Alongside this, the flight log recorded a cluster of "impact or hard landing" G-spikes (3.1–3.5 G) at 0:33, 0:48, 0:53, 1:17, 1:22, 1:33, 1:57, 2:46 and 3:09, several of them coinciding with steep-attitude warnings (45–70° from level, the steepest at 1:22, which also lines up with the 3.5 G impact flag at the
