High stability rotorcraft

Posted by eduardo on October 17, 2011 at 5:03am

Well,

here are a 1.8 year old video that i edited to show how are the video footage of high stability rotorcraft.

This is one of me first test with full-HD video cam.

As you can see, this platform is much more stable as ardupilot.

No wooble or vibrations.

Some balance in the video are due gimbal servos. I am using nicoleto gimbal.

This setup are using default PID.

OBS: from 2:00 to 3:00 the video are post processed to remove some wooble.

 

Today the platform is much more stable and using high speed servos on the gimbal

    As i say ... i do some post processing at 2:00 to 3:00

    about wobbling ... arducopter have much more wobbling.

    This is an old video .. more than 1 year ago and using an octo with default pid.

    This octo are tunned to make pictures at 800m alttitude not for video.

     

    i try to put the arducopter on my frame tons of times and never get this stability.

    I used high speed moded esc, conventional esc etc . wobbling continue.

    I will try again this week and post my resusts.

     

    Sebastion, about altitude control ? i never get good altitude stabilization with arducopter.

    Hi Eduardo, very nice video.

    you can kindly provide information or links on the adxrs giro mod on FC 1.3 ?

    Yes, the Ascending Technologies GmbH hat a patent on V frame here (since 2008),

    A H frame should be still free.

    Anyway, if you will become rich from the brasil V frame patent, I claim 5% of it (idea tax ;)

    wow ... patent for the frame model ... strange.

    i will make a patent for V frame here in Brasil jejejejje

     

    H and V this is the best frame for professional video. Big aperture angle.
