Maintain the centreline
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

The rest of the report
The flight began with a departure roll from runway 34 at KFHR Friday Harbor Airport. The Pesim FPV Drone Racer took off with a takeoff distance of 425 meters, which accounted for 41% of the runway. The liftoff speed was 81 knots, and the local weather conditions at the time were a temperature of 16 degrees Celsius and a wind speed of 2 knots from 270 degrees, resulting in a 2-knot crosswind and a 0-knot headwind.
As the drone climbed away from the airport, it began its enroute climb, which started overhead Friday Harbor. The drone climbed from an altitude of 1,129 feet above sea level to 1,599 feet above sea level, an increase of 470 feet in just 1 minute, while covering a distance of 1 nautical mile. Following the climb, the drone entered a level cruise phase, which lasted for 3 minutes and covered a distance of 3 nautical miles, 1 mile north-west of Friday Harbor.
The final approach to runway 34 at KFHR Friday Harbor Airport was initiated from the south, with the drone heading 358.0 degrees at an altitude of 389 feet above ground level and a distance of 1 nautical mile from the runway. However, the drone was forced to execute a go-around at 0 feet above ground level, likely due to a loss of altitude or a navigation error.
The drone subsequently landed on runway 34, with a threshold speed that was well above the target speed of 84 knots. The touchdown distance was good at 151 meters, but the touchdown speed was a little fast at 79 knots. The touchdown rate was excellent at -93 feet per minute, and the runway touchdown alignment was perfect. The local weather conditions at the time of landing were a temperature of 15 degrees Celsius and a wind speed of 2 knots from 270 degrees, resulting in a 2-knot crosswind and a 0-knot headwind.
The total landing distance was 454 meters, which accounted for 44% of the runway. However, the runway rollout alignment was slightly misaligned by 9.8 meters from the centerline. The taxiing to the parking area from the runway took less than 1 minute and covered a distance of less than 1 nautical mile.
In total, the flight distance was 8 nautical miles, and the flight duration was 12 minutes. The drone used 3 kilograms of fuel during the flight.
