    Another "dropping from the sky" event

    I realize this thread is a little older but you made a great analysis. It's really not that there is less air, the air is less dense. Because it is less dense its cooling ability declines. This is one thing I'm worried about flying even at my home altitude of 5175. I have computed the air...

    Altitude performance question

    Thanks sir! I don't know the altitude I will fly until I've tried it. I can think of three reasons to get a quad: 1) fun.. Just flying about 2) Inspecting my property. Only an acre but would be nice to fly to various places and look at stuff including my roof (hail damage etc) 3) Prairie...

    NEW RECORD {update} [video is up] 6.09km... 3.8mi !!!

    Re: NEW RECORD... 16,543ft... 5.04km... 3.1mi Very cool stuff. I don't own a PV2+ yet. Still considering. I am an electrical engineer, computer programmer by trade so the different hacking to get distance reminds me of my ham days trying to bounce 1W off the moon or the ham sats. Question...

    Altitude performance question

    Ok I was gonna order some but you are the second person to say they contribute to VRS. Thanks for the info.

    Altitude performance question

    Thanks for the reply! Ya "settling with power" a condition where you can be at max power and still going down because you are unable to generate the right flow through the rotors. The right recovery (at least in a hell) is ANY lateral flight. I guess in the phantom when it gets in that...

    Altitude performance question

    Hi All, Considering a phantom 2+ but I live at 5175 feet at the base of the rockies one of the reasons I have not considered a cheaper solution. Today at my home we have 95F, 16% humidity and pressure of 30.12. This calculates to a density altitude of around 8000 feet. How does the bird...
