Hello Jcamilo
So the blue angle represents the direction the controller / smart device is pointed - that should point towards drone
The green angle is the direction the front of drone is pointed or flying
Keep in mind that on your smart device or phone that if the compass is not calibrated or a poor GPS signal it can show the the controller pointed differently than it actually is
If you tap on that circle it will enlarge the map,
btw... i have to calibrate the compass on my android device frequently - sometimes it 180' off
Does this help or make sense?
