Arducopter 2.3 tuning Stab_P for Nav video scenarios

Hello again everybody,

Round two of "organized testing"...today I decided to keep my Nav settings from last time(see previous blog post) and only play around with the Stab PID parameters to see what kind of effect they have on Loiter. I started off by increasing my Stab_P from 3.5 to 5, then to 6, and finally to 7. I noticed a significant improvement…

Getting the full POV image requires lying directly…

Arducopter 2.3 Nav tuning video scenarios

Hello,

This is my first blog(and I mean first ever anywhere) so please excuse the lack of the "bloginess" quality :)

I've been in testing mode with APM1 since the release of Arducopter 1 code. After a couple lost and crashed quads, I decided that my strategy for testing arducopter from now on is to start with a cheap frame/motor/prop combo, basically to…

MyGeekShow finally flies an APM!

 

This week I constructed, installed and tested an APM on my Nova. Everything went great! Stabilization worked like a charm and RTL worked flawlessly! Can't wait for the next few months as I explore this "new" technology. (well, new to me!)

 

Thank you DIYDrones for the AWESOME equipment and software... very, very…

JSBSim Trimming Demo for F16 and Shadow UAS

A gui for JSBSim is demonstrated. The gui is capable of trimming any aircraft modeled in JSBSim at various flight conditions. It can simulate the aircraft at the calculated trim conditions, save the linearizations around these trim states, and output the linearization to a form readable by ScicosLab. The software is demonstrated on the standard f16 model included with JSBSim and a shadow UAV model, part of arkhangar. The linearized state space models output at the trim…
