I have an Iris+ and when i fly it whith the short legs everything seems fine. When I attach the long legs and gimbal it flies fine (Climbs perfectly, turns perfectly, etc) for 4-5 mins and then it's like it decides to land on its own, even if im all the way up in throttle.
I sent my logs to 3DR and they just said "There is nothing wrong with your system, the problem is you are too high from sea level" (Which i though "what an easy way to end the conversation and say its not our fault!"). I am in mexico CIty which is about 2400mts above sea level.
What do you guys think of this? Anyone had any similar experience?
