Kraken130 + Pixhawk?

Posted by Paul Jenness on February 6, 2014 at 3:39am

Hi

Have you guys seen the new Kraken 130 from Foxtech.

http://www.foxtechfpv.com/foxtech-kraken130-octocopter-arf-combopreorder-p-1335.html

What do you guys think?

Im impressed with the build and strength and flight time. The airframe and electronics are $2000

However the FC itself they suggest is also $1200 (DJI A2M - $1800 ZeroUAV)

Im wondering if the pixhawk would be enough to conrol it?

What do people think?  (Besides it not really being DIY)

Cheers

    Release the Kraken!  

    Kraken build in my workshop in Manchester, CT.   This Kraken is carrying an Aura2 3 axis gimbal and Canon 5D camera equipped with a Teradek HD Transmitter to send live HD video to the ground.

      Hi, I am about to tune a newly built Kraken.

      Could you please share a dataflashlog or your PID's , so I can start out with something closer to tuned ?

      Currently I have only one 6s 16Ah pack - and it would save me valuable tuning time once it's less windy, and it's winter here in northern Norway, so a shorter tuning/freezing time would be nice :)

      That's great.  I'll  add to it.   I'm starting a brand new Kraken / Pixhawk build on Tuesday next week.  Was planning to shoot video at the same time.   

      Does anyone who's already built a pixhawk / kraken have a parameter file to share?  I was planning to use autotune, but any head start I can get would be appreciated.

    Why not?! Go and explore things on Earth!

    I have a kraken and probably have over 100 flights on it now. I have had two motor wires break(they are hard and brittle) and I was one of the first that experienced the capacitor issue. I new about long power wires but figure they tested it and it wasn't an issue. I had an esc go out while I was in the middle of the ocean and barely got it back. It has an A2 on it right now but if I had it all over I would put a pixhawk on it. What ever you do make sure you secure the motor wires so they don't vibrate or get mishandled. I ended up changing the motors and esc's to brands I trust and mounting the esc's in the center plate.

      Hey Neil,  glad you got it back from the ocean..   and thanks for sharing your experience.  for me personally i would like to see if we can grab the attention of someone that has a Pixhawk on their Kraken. We are very close to getting some initial tuning flights.  I would love to hear other experiences with the PIDs and  ESC sync issues .

      I feel pretty good about the sync issues after a fair amount of research it appears that the ground wire on the esc needs to be present.  I have yet to decide what to do with the power lead (red) i checked the voltage on that wire and it is not seeing any return voltage from the ESC and this, i think to be expected from an opto ESC.

      I am curious how are you guy powering everything .. ESC. Pixhawk and gimbles?  i am thinking that i am gonna be running separate batteries for each .. (2 person setup)

    Ha

    You guys  are ahead of me now.

    I bought the Kraken foolishly sa my first copter.. was great to build for experience...

    Then I did my first take off and realised I was quickly out of my depth.  So got an Iris to practice on first :)

    Now I need to rebuild the Kraken..I have the kit to move the ESC to the centre plate. Hope to do it in next few weeks.

    I dont like any of the leg offerings, Im interested in finding a different solution that fold down like 4-8 stilt legs from the arms. It will balance better and fold up nicer.

    Good luck guys!!
