Take off from the yard, spray six 36 m rows of the crop block 2.5 m above it and 4 m apart, pump on along each row and off at the turns, then come home and land on the pad. Fly it yourself in Loiter against the par times, minding the trees on the west side and the power line on the east, or switch to AUTO and watch the survey grid fly itself.

Break it

Put a real build mistake in, even mid-flight, and watch what it does. A crash replays in slow motion and says why.

Mount the flight controller backwardsIts arrow points at the tail, so it reads every tilt the wrong way round.

Swap the props roundEach prop sits on a motor that spins it the wrong way: that corner pushes down.

Skip the motor direction checkOne motor spins the wrong way, and nobody looked with the props off.

Skip the accelerometer calibrationThe flight controller doesn't know which way is level, so it won't arm.

Run the motors over their ratingToo many volts for these motors' KV: the ESCs lose sync at full throttle.
