"Hi all, I'm currently building a quad from scratch and I'm facing a trouble with Accelerometer and vibrations from motors (about +/-0.5g/axis when running fast). I know that I have to balance the motors and propellers but I looking for…"

"I have been using MPU6050 quite successfully - but I do not use third-party libraries, I write my code from scratch. However, I have a blog post at http://flightcontroller.blogspot.com/2015/06/mpu-6050-configuration-and-operation.html that…"

"Hi Carsten, When you say that the BNO055 "outputs quaternions and euler angles directly from the chip (the chip has a Cortex M0 CPU built in that does all the hard work)" , how does that work exactly? Currently I'm working with an…"

"From what I read in the datasheet, BNO055 in data fusion mode provides updates at 100 Hz - is that enough to control quad? On my custom board doing all orientation calculations in code using DCM algorithm on PIC24EP using MPU6050 I get about 400 Hz…"

Carsten Groen replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"I have had around 50 modules (433 MHz) from HK. I could get a few of them to connect to 3DR radios, some of them only sporadic, most of them no connection at all. I have my own developed boards using Hope-RF modules (again at 433 MHz), and these…"
