My new TriCopter made its first long-duration test flight today, fully autonomous. Using APM2.8, ArduCopter 3.2.1, APM Planner2 on linux. It flew the same 15 minute mission repeatedly until the battery got low. After letting the battery recover fo

Hope this isn't a stupid question:
Is there a difference between 433mhz and 915mhz antennas supplied with 3DR style radio modules, and if so how can i tell them apart?
I've been struggling to get a decent telemetry link with knock off versions o

First post (possibly of many!), just to see if anyone else has encountered issues with the Minihawk/Pixhawk Mini, when connecting the GPS/Compass or the 3DR telemetry.
Both have different symptoms...

EKF / DCM Check Failsafe
Copter 3.2 adds a DCM heading check and an EKF (Extended Kalman Filter - Pixhawk only) check to catch flyaways caused by a bad heading estimate......
I received two errors simultaneously in my log. ERR: EKF_CHECK-

I am building a quad using APM 2.8 and a 10 channel PPM transmitter (FlySky FS-i6S). I have configured the channels on the transmitter , and set the parameters on Mission Planner (1.3.41) for the auxiliary channels.
However, when I try to confi

I have been working on a small blog about remote sensing and airborne survey. It has a focus on UAV remote sensing, and general trends in the airborne survey industry. Its a work in progress, and I will be adding new content regularly. If a

For a university project, my team and I are working on a self made multicopter drone with wings. The benefits are obvious (longer flight time, greater distance). Also, we will build it so it can sustain difficult weather conditions.

I am currently working on a hexacopter. After completing the assembly I tried to calibrate the motors. One of the motors didn't spin properly and smoke started coming from it. This happened twice. I don't know if the problem is with the motor or th

I am a master student with background in control theory. In my project I try to implement a nonlinear controller for a custom built Hexacopter.
The controller was simulated in Matlab Simulink and it can produce control in 2 forms:
