    I am running an x8 config

    Mk fc 2.5
    NAV
    BL 3.0 version cool
    t motor 4012-9
    RTF-CSX8-MK-HL

    Here are my GPX files for two different runs. It is flying perfect.

    Wondering why the engine currents are so different. Please have a look at my gpx files and comment if you have any idea why.

    Thanks Glen

    I took a look, expecting to tell you that sometimes the BL 3.0s need to be properly calibrated. But in your case, I don't think that's true. The reason for that is your temperatures sort of match the current mismatches. If the copter's behaving, then I'd say you probably have one boom that's out of "plumb" vertically. In other words, one pair of motors may be tilted, causing others to over-work to maintain yaw stability. Search the forum for posts about how to level your motors. That's a good place to start. Good luck.

    Thanks Steve,

    I checked all the motors they are all level. I talked with quadrocopter and they suggested I check temps of the motors, which all are the same. I will keep watching it. Thanks

    Cheers Glen

    How about the left/right and front/back balance of the copter when fully kitted out?

    Thanks Steve,

    That is the one thing that I did not check when I was flying it. We were adding weight to get an idea how much we could safely fly at, it was mostly centered but I never checked exactly. I will check that today.

    Ah the simplest things!

    Cheers Glen
