    My P3 has been flying almost 40mph in reverse, but no more than 16-18mph forward. I at first thought it was due to the direction of the wind, but flew it again today with no breeze whatsoever and still Flys much faster in reverse...any ideas how to fix?...Thanks

    How high? The wind aloft can be deceiving. Do your same test but try rotating the bird 180 and flying away backwards. What you are saying sounds normal for slight wind at elevation

    I have noticed this speed difference at different altitudes but always above 100ft...your idea of rotating the Phantom is a good idea...have never done a stick calibration ...haven't seen any issues as to why it was needed...do this k this may help?...not sure how to do it...but I'm sure there are some YouTube tutorials on how

    Hi Dan..thanks...have never done a stick calibration...never seen a reason why I thought it was needed...thought it was only needed for direction problems

    If your numbers are correct and there was no wind factor it's very unusual.
    Easy enough to check though.
    Just do a few runs in the same direction but facing different ways.

    Thanks...will try that. If it wasnt a wind factor...Do you know of a fix?

    Those sort of numbers are exactly what wind does.
    I'd be surprised if there is any fix needed.

    Don't you think it would just be easier to just try a simple experiment rather than posting this to the forum? Spin the thing 180 and try flying it... If it goes at the same speed then its obviously the wind. If it's slower you have a problem...

    I think it is possible. I say that because I have been doing some testing with adjusting pitch. And in doing this I stand at the side and observe while flying forward say 15 yards and then in reverse the same 15 yards and focus on what the pitch appears like at it's furthest point.

    Thanks Ari...All things considered, it wasn't the smartest question...I'll try not to point it out if you also ask a silly question.
