Ardu(tri)Copter Mega

Posted by Max Levine on February 7, 2011 at 8:00am
Ok, here is my Tri-Copter frame for ArduCopterMega, thanks to Jason ;)
I did some mixing here :) 
Original frame design is from rcexplorer's tri-copter:

Center plate is laser-cut from 3mm plywood, there is 2 bottom side options:
One to attach t-rex 500's landing skids

tri-max%20%284%20of%2024%29.jpgTop plate is modified too for APM housing or original ArduCopter carrier plate:

For tail i used this servo

here is a long video to waste some time ;)

9X4.7 APC props (all CCW).
15X15mm 1mm thick 50cm long Aluminium arms... 
center and servo mount (for 15X15mm arms)
the weather is bad here :(
so no videos for now :( 
Good flying to ALL !!!
next will be that:

    yes i found it already. However i must first get the magnetometer module to draw forward and test ACM.

    I even didn't try APM in my airplane ;o(,

    Thanks for navigation.

    Yes, thats how the Mikrokopter has it..

    Here you can see it quite good: http://gallery.mikrokopter.de/main.php/v/uploads/mischer+X8.jpg.html

    How about a extra page in the configurator, where you can ajust the motors...

    How should I implement the speed differential top to bottom. Is it a scaled value like 80% of the top?

    Let me know and I'll add it.

    @Palo
    This is how ACM output to motors,..
    In CLI chose frame type 'tri' in setup menu...
    There is a readme in ArduCopterMega folder, with all the comands :)

    Max, that is so interesting with the Y6, good to see progress on that.
    I am in the process of building up a heavy lift Y6-arducopter-electronics are sitting waiting here ;-)

    Looking forward to hear about your Y6 progress...
    Good to hear it will have adjustable motorspeeds for top and bottom..

     

    Regards

    When i have read arducopter docu (Connecting your RC equipment) it is all clear now ;o)

    Max thanks a lot for wiring diagrams update. Anyway you suggest left ESC connect to output 2 (APM 1.4) and rear ESC and servo to output 4 and 7 respectively.

    I would expect rear ESC connected to output 2 just (for elevator) and servo to output 4 (rudder). I thought so  because of APM in airplain configuration do this way. Are those APM outputs remaped in arducoper configuration?

    Hi Max,

    Tri-copter? Not yet.

    I will probably try to make a 3D printed quad/hexa frame first. :P

    (That 3D print idea is sticked on my mind...)

    @Palo 

    Jason is updating ACM code daily,it can be buggy some times :), IT'S ALPHA CODE, be ready to crash :) or test it many times on the ground :)

    Go to http://code.google.com/p/arducopter/wiki/Quad_Radio and just connect it, as i updated in the post.

    ACM is in  HERE.

     

    @Jason 

    Flight in the video, is on ACM default PID, don't see any reason to change it, maybe speed it up a bit on the YAW... response ?

    @Daniel 

    Jason is the boss on this one ;)

    but yes, i did some testing on the Y6, it was OK.

    and it definitely will have top/bottom motors speed adjustments, Jason ? ;)

     

    @Sandro 

    Thanks, Man. Are you starting to build one ? :)

    In the CLI you go to setup and type "frame tri". That's it.

    Y6 is coming. I'll wait until Max is ready to help test.
