CamLifter Heavy OktoKopter - Mikrokopter board - Reflashed ESC F30A - Flight test in strong wind

Posted by Marco Robustini on June 10, 2012 at 11:00pm

Hi all! In this video the first test of my new heavy CamLifter OktoKopter.
The specs:

- CamLifter Heavy OktoKopter - Carbon frame and landing gear by Klaus Peters (kopter4u.eu)
- Battery holder by Alessandro Parisi (AleBS)
- AltiGator A3536-LE Motors
- APC-E 13x6.5 Props
- HobbyKing 30A ESC (F30A) reflashed with "SimonK Firmware"
- AfroI2C converter
- Mikrokopter flight board
- 3DR Radio 900 MHz telemetry
- FC "hot swap adapter" by Marco Robustini
- 4S 5000 mhA 30C LiPo (x 2)

Using my "hot swap" adapter" I can remove the Mikrokopter board and install ArduCopter APM2 in just two minutes, without remove a single cable.

Bests,

    Really nice Marco!  

    I really love the sound of these ESC/motors, I need to update my ESC firmware, I've always chicken out of doing it but every times I see a video with the "SimonK Firmware" fixes it remind myself how better things can be. 

    Really strong wind and very stable, again good job! (and dont send this one on a crash while testing latest code, she is too much of a beauty!)

    I guess the most impressive feature is no doubt the position hold. It's dead on. I don't know what algorithms are in use here but they must be some very impressive ones. I also know that the current Arducopter code may be already pushing the limits of Arduino regarding calculations made. When searching the web for gps accuracy algorithms, I found some interesting algorithms wich I don't know if are already beeing applyied or have any possible implementation. One of them is http://stackoverflow.com/questions/9184418/algorithm-theory-for-gps... others mention using TLS algorithm (total least square). I've downloaded a paper of Total Least Mean Squares but honestlly don't know how to apply it or even if it's possible, but it would be great to have a position hold like that :)

    @Perelo

    Thie page shows how to connect XBees to he MK and has worked for me:

    http://www.mikrokopter.de/ucwiki/en/xbee

    If you look at how to connect APM 2 to XBees in the Wiki, and then the difference for 3DR radios, that should give you the information to adapt the MK-Xbee connection to 3DR no?

    Hope it helps

    Hello Marco! Nice platform you've got there!

    I fly both APM2 and MK and I wonder how to connect and configure the 3DR Radio to my Oktokopter, do you have any schematics on that?

    @ThomasB

    Ah! That would make sense!!! Thanks

  • ThomasB June 11, 2012 at 2:18am

    @Crasher

    I assume that the "AfroI2C converter" is used for I2C to PPM conversion.

  • Crasher June 11, 2012 at 2:01am

    @Marco

    So the reflashed ESCs talk I2C????

  • Eric Tweet June 11, 2012 at 12:41am

    I was wondering the same thing (but I don't speak Italian!)

    That thing does look solid though - very smooth and amazing loiter, and in that wind! It is pretty impressive, and I'm glad to see you behind the 'wheel' of an octo again.

    Cheers
