Good day! I very glad You reply. This project now is not finalized. But I hav many tests. Until I have only blog in russian. You may see url in my profile, I don't have permision to write URL. And I make translate it in englishe at rcgroups with name Maksimuzz. As seems an interest flight was in a slow motion, but with bad GPS positioning, And the one more flight was not so good recorded by the camera. My plane landed at field, because battery was bad. You can see landing at left down angle of screen. The Dragon flight was about 1.5km, a point 4 offset was about 3 м relatively card route.
