  • There are a few changes I made, that added the extra weigh aft of the main shaft.

    Metal anti-rotation bracket

    Metal Tail Servo Mount

    Extra Torque Tube Bearing inside tail boom for reduced vibration.

    Carbon Fiber tail pitch control rod assembly.

    Bluetooth sensor mounted on tail boom. 

  • Thx for the comments, Due to extra weight in the tail, I was forced to move the 6s pack further out toward the nose of the bird. I still need to keep experimenting with ithis as I don't like the fact of having all that weight out on the nose. It seems to increase the pendulum effect so I might try putting a small 2s lipo on the bottom frame and move the main 6s lipo back up towards the main shaft. Good luck with your build your gonna love the 550, I fly it more than my 600.. :-)

see all

  • lol 1:44......i feel ya! May I ask why you have extra weight in the tail??? Or, why is it tail heavy and your cg is off? Thanks in advance

  • I noticed the battery far forward on the tray! Is the CG that far off? I'm building one now for 12s and curious about the CG. Nice flying!
