Autonomous RMRC Anaconda R/C Plane Project

Posted by Thomas J Coyle III on February 3, 2015 at 11:38am

Hi All,

To be able to help test ArduPlane firmware I have been putting together a RMRC Anaconda twin boom pusher R/C Plane Link. The Anaconda is not an acrobatic air frame and is designed more for endurance flying with the capability to stay in the air for around an hour. I plan to use the Anaconda in a mini OBC to be held here in Southern Florida sometime in the future. 

I have the fuse, the wings, and the tail boom pretty well completed so I thought that I would share my installation of a Pixhawk flight controller and associated components into the Anaconda fuse.

My next step in the Project is to calibrate the sensors and the compass and then load in and customize an Anaconda Parameter File that is available on the RCGroups RMRC Anaconda thread Link . The Anaconda thread is full of good information about what and what not to do when either building the kit or flying the RTF version. I will then attach the ESC and servos to the Pixhawk servo output bus along with a 5.6vdc zener diode to clamp the servo output bus power rail and then begin flight control ground testing.

      @Scott,

      I am using quality Hitec analog servos and the ESC in the Phoenix Edge can produce 5 A peak current. There have been some members who have switched to a CC 10 A BEC which I do have on hand.

      The only additional RMRC components used on the plane are the T motor and the 4S batteries.

      Regards,

      Thomas. I'm actually using the CC 20 amp BEC. That's why it became so concerning to me when the symptoms started happening. I will probably replace my servos in the not too distant future. The response 'your BEC doesn't provide enough power' that was stated in the thread didn't sit to well with me.
