Hi !

I really enjoyed both the videos; 18km & 15km, excellent.

I can see that for very very long periods, the plane position was not getting updated on the map, why ?

Thanks for the compliment Rana,  because i'm flying at lower altitude the 3DR telemetry antenna (dipole) on the plane couldn't get clean Line Of Sight connection which is why it cut off around 6.2km especially during banking which is why the ground station didn't get data feedback. If i could get it higher around 200m more higher than the ground it will be illegal altitude to operate on UAV craft. So i keep it low altitude to comply with UAV rules. I'm planing to fly long range over the ocean soon at low altitude since it doesn't have trees and obstacles.
