Senior Telemaster Flight + Glass Cockpit Display



I just thought I'd share a quick video (and picture.) This is a movie I made of a replay of a real flight a couple days ago. I collected the data remotely while the flight was in progress via a maxstream radio modem connection between the aircraft and the ground station. I saved the flight data on the ground station and then can replay it later in FlightGear. The display is a "glass cockpit" style display I'm just…

Ardupilot 2.6.2 Beta



This beta brings support for the new MediaTek GPS unit. The MTK works great and it's very light.

I've also added some bug fixes including:



  • Auto Trim - (on by default) When you enter any flight mode from Manual, you'll save your current trim values. Great for trimming your plane…

Ardupilot Mega's First Complete Mission



This only ran in simulation (Mega has an internal mission sim), but it shows the mission script hitting three waypoints and returning home to loiter. The mission scripts can be MUCH more complex.
I'll post the code in the…

ArduPilot Mega moves off the bench and into the air

Progress report: The ArduPilot Mega v1.0 firmware has reached a flyable state!





There is a lot of work left to do before v1.0 is ready for its beta release, but things are progressing. At present STABILIZE and FLY_BY_WIRE_A are working well. Full 4 channel control has been implemented. On board data logging is really making me smile.



Jason Short and I are working closely together and working through the… Continue

GPS-INS EKF library

I've been writing a GPS-INS integration EKF for my Master's research. This may be the first implementation of this algorithm to be published as Open Source software and you can find it on bitbucket. See also some discussion on the OpenPilot forums.

I though this was kind of interesting.

The video in the link is to a video of a camera that uses electromagnetic induction to supply power to the camera from the power lines. Near the end of the video they are showing a 4 armed copter that has two motors with blades on each arm to make an octocopter. They said it will be able to lift the 10 pound camera load with no problem. Has anyone else ever…

On My Way...

Hey Guys! (meant in the most gender neutral of ways),

I have taken my first real step toward building a DIY UAV! This will be boring to most of you, but to someone as far behind the curve as I am, this is HUGE. This community has come so far, and in such a relatively short period of time, that autopilots for RC planes are almost plug-and-play. However, I am determined to learn the basics of process control before moving on to…
