Flight Times at High Altitude

[Humming.bird i1]

Hi Folks,

We have a potential client who is in Santiago in Chile and he is asking how the performance is affected by altitude. His altitude is typically about 3000m, therefore can anyone on this forum who lives or has had experience of flying at higher altitude please advise on the typical percentage flight time loss, and confirm what altitude, and the typical temperature. I can then go back and advise on the expected flight times based upon normal altitude flight.

Many thanks in advance

Hi
I live at 8000' ft. and fly with the i1 & i1 pro, the 1360 hi alt. props are a must at this elevation. the X3 well do a lot better for you then the X5 simply because of the extra weight of the X5.
