Hello All! This is my first question here. I have built a new quadcopter using s500 frame. I calibrated both accelerometer and compass using mission planner. I am having problem with the outputs coming from APM board. The problem is this;

I am flying with arducopter in my multicopters more than 5 years, and this is the first time I can’t solve the problem by myself.
The problem is: after 8 or 9 minutes flying in pos-hold mode, my quad start to drift in circles. And the circles are b

Hi!
I'm wondering if the IR-Lock (for quadcopters) uses data from other sensors to estimate the quadcopter's position relative to the beacon, or if it just uses the data from the Pixy Cam?
Thanks in advance!
I want to send a non-RS232 type signal using the 3DR telemetry radio. No start, stop bits etc. Just bits to be reflected exactly on the other end.
They do have a format but its not the standard RS232 async format we all know and love.
I'm trying to inj

Does the pixhawk have to be connected to mission planner for you to fly in loiter mode?

I'm using 3DR gps module for my ground vehicle project. It has Ublox LEA-6H-0-002 gps chip. I connect the module to my PC, and the U-center shows that the output is in UBX format. But my micro-controller can only deal with NMEA 0183 sentence

For a research I'm doing, I would like to use a quadcopter to land on a glacier (but a crevassed area, a kind of no-go-zone ...) in order to leave a sensor for a few hours before flying back to me. As I will be far away (but still in the
