X-Plane interface

Started this discussion. Last reply by avionics Aug 16, 2011. 8 Replies

I have been trying the x-plane interface over the last couple of days and could't manage to tune the airframe - it always ended up spiraling in after switching to any of the stabilized modes. This…Continue

RTL vs.Loiter

Started this discussion. Last reply by Luke Jun 23, 2011. 6 Replies

Is there any way to distinguish between RTL and loiter via the Mavlink? From what I can see, when an RTL command is active it is implemented as a loiter at the home position, so the flight status…Continue

Rudder Servo Direction

I am trying to confirm that I have the servo directions correct in stabilize mode.Aileron and elevator are easy enough - pitch the aircraft nose up and the elevator should move trailing edge down,…Continue

Extracting data from tlog files for plotting in Excel

Posted on May 11, 2012 at 6:00pm 53 Comments

I wanted to analyze some data from a tlog file and figured that Excel would be the most flexible  way so I created a little utility to extract the data I was interested in and save it as a comma separated value (CSV) file. Each selected parameter is in a separate column, and Excel can open  the csv directly.

Note that it can't open the tlog file directly. You must use the Mission Planner to convert it to txt format. so:

1. From the APM Mission Planner…

Ardupilot control using OSD menus

Posted on January 4, 2012 at 3:06pm 4 Comments



I would like to fly with live video and goggles, but this makes it tough to make any changes on the mission 

planner. To avoid any need to take off the goggles I integrated a series of menus in the OSD.

My setup, as reported…

Ardustation as a terminal

Posted on August 12, 2011 at 10:00am 14 Comments

While the progress on the APM Mission Planner makes it more and more attractive to bring the laptop out to the field for each flight, sometimes the simplicity and sunlight readability of the Ardustation is what I really need. The problem was that I kept adding more pages and busted the memory limit of the…
