Hello, flight - again

You wrote your first program on echo.pitsco.com. Now let’s do the same thing in AT-66BL so you learn the one big difference: programs start with the green flag (a when 🏳 clicked block), not with take off.

Nothing runs until the green flag is clicked - it's the 'start here' of every program

Fly in a clear space with no people or pets nearby. Before you click the green flag, know where the red stop and no-entry buttons are. Clicking them ends the flight immediately.

​
The workspace, one more time

Open Program mode. Blocks are on the left, your canvas is the middle, and the run controls (green flag, stop, no-entry, save) are top-right.

​
Build it block by block

Start with the green flag

Open Events (yellow) and drag out a when 🏳 clicked block. This is the “start here” for every AT-66BL program.

Add take off

Open Fly (blue) and snap a take off block under the flag. The drone will rise and hover.

Hover with a wait

Open Control (orange) and snap a wait [1] seconds block. Change it to 3 so the drone holds steady for a moment.

Finish with land

Back in Fly, snap a land block at the very bottom. Always end a program by landing.
Your finished stack reads:

​
Run it

Check your connection

Make sure the Bluetooth icon shows you’re still paired to your drone.

Click the green flag

Click the 🏳 green flag in the top-right. The drone takes off, hovers for 3 seconds, and lands.

Stop anytime

If anything looks wrong, click the 🔴 red stop to end the program, or the 🚫 no-entry button to cut the motors instantly.

​
Save your work

Click the 💾 save icon and choose Save. Give it a clear name like first_flight. You can reopen it later with Load.

​
Now make it yours

Longer hover

Change wait 3 seconds to 5. Does the drone hold longer?

Add a move

Between take off and land, add vertical move up 20 cm and watch it climb.

Add a spin

Try turn right 90 degrees before landing.

Add a pause

Stack two wait blocks with a move between them for a step-pause-step feel.
Instructor: the #1 beginner mistake here is forgetting the when 🏳 clicked hat, then wondering why the green flag does nothing. If a student’s program won’t run, check for the yellow hat block first.
Every program should end with land. If it finishes without landing, the drone keeps hovering until you hit stop or no-entry.
You built a when 🏳 clicked → take off → wait → land program, ran it with the green flag, and saved it with a name you can find again.

Next: advanced programs

Add loops, variables, decisions, and custom blocks to build real missions.
