Hi to all!

I am from Brazil and I am finishing my thesis to get my Doctor's Degree.

I have an energy model for quadcopters and I need some data to do a final check in the model.

I have spent the last two weeks tryng to find those files in the Internet.

I need the binary log or DF log of the Ardupilot such that I can convert it into a .mat file. Then I can use my Matlab program to read the .mat file and d the rest.

Please, if you have files like that you can make it available to me, please  post here or send to my email : joao.marins@inf.ufpel.edu.br

As additional info, I need to know:

- the model of the quadcopter;

-the weight of the quadcopter;

- the propellers used for the flight;

- where the flight took place.

I photo of the quadcopter would be an extra so that I can put that  in my thesis.

I will be very grateful if you can help me.

Best Regards!!

Hello,

I am looking for recommendations for distance sensor for quadcopters. I want to measure the altitude of the quad. I have used a Lidar Lite v3 and Maxbotix EZ4 sonar before. Looking for other options since Lidar Lite's performance is great but is quite costly.

Thanks in advance.

P.S.: Using Pixhawk as flight controller.

If you engage RTL when the aircraft is on the ground the Flight Controller will automatically detect "landing complete" and disarm the motors.

If you can, use a switch to trigger RTL (channel 7 or 8).

Fly the aircraft away from the launch point and put the aircraft in Loiter.  Now you can flip the RTL switch.  

The aircraft sound ascend to 15 meters, hover for a moment and then head towards the launch point, hover over the launch point and then land. Turn RTL off, put the FC in Stabilize and disarm...

The FS kind of works now but I can't get it to go to RTL when I turn the transmitter off.It will say disarm and shuts off the motors. I have it set to RTL it just won't do it. I even moved it about 10 meters away and it still doesn't work. I have RTL on my three-way switch and that works. I am afraid to try and fly it at this point I don't want to crash it this soon. Any advice?

Comment by Clifton Hipsher on June 13, 2017 at 6:28am

The short answer is the power system (motors/props/battery) is not matched to the weight of the aircraft...

Hello good night greeting from uruguay I have a problem that has already been with my head in another time I have a drone in a chassis Q450, afro esc 30 amp, multistar 2212 engines, arducopter plate, with power module but I have engine speed problem Are not enough and the 5 minutes of flight is left without power what can be my problem

Comment by saTxRxasis on June 6, 2017 at 4:42am
30 kgs on quad configuration? You')) need at least 1100 mm quad frame because you'll need @300" kv motors which will spin 32-34" propellers @ 12S LiPo pack.
IMHO, this quad would actually need a lot of cost and by using quad X4 config you'll get no some kind "assurance" because quad X4 don't have redudance power when one or two motor get failure when flying. Better use Hexacopter or Octocopter config. If you still insist using quad config, maybe you should tried quad X8 with coaxial motors.
