About Me:
I have always been pretty interested in flight and RC models, which led me into doing a Masters in Aerospace Engineering. As UAVs bring together so many subjects (aerodynamics, power systems, control systems) into one affordable package its an obvious hobby!
Please tell us a bit about your UAV interest
Tricopters, traditionl helis, autonomous gliders and soaring.

"Hey Mike,
All the gui does is update the Simulation object on a timer and allows setting params. If you can't get Matlab you can just do a simple script like this:
figure;
ax=gca;simulation = Simulation(ax);
for i=1:1000 simulation.Update(0.01);…"

"Hi Philipp,
Nice project and glad that you found my soaring code useful. This has now been merged into the ardupilot master repo so now would be a good time to contribute your enhancements back to the codebase.
Cheers,
Sam"

"Hey Mike,
Yes I am also very pleased it's going into master! It has really re-invigorated my motivation for this project and I'm working on some new features now. Wow yes it seems a long time ago that I used that code, I now do most of my testing…"

"Hi Andrew,
Great new about X-Plane and nice to hear you're getting involved in the soaring stuff! I've successfully used this plane in the past:

"Well done that was quick work! See your messages. I haven't tried with that version it would be interesting to see if it's better - with the gitsly branch I was getting lots of lost packets within 300m when transmitting serial but could go several…"
"Hello all, unfortunately haven't done any work on this lately. I found that the range from the OpebLRS system was drastically reduced when passing through the serial MavLink data (on the gitsly branch). I'd like to try it with the current OpenLRS…"
"Hi Andrew,
I'm happy you think the soaring functionality would be a good addition to master. It would certainly save me having to keep the soaring fork up to data, which I have to say I am not particularly diligent in doing.
Simulation has been…"

"Hi Kelly,
Thanks for your interest in the project! Always good to have people testing the code. I think the Radian is a great platform for soaring experiments. I need a new one since I lost mine in a tree! It does need some thought in terms of…"

"Nice flight logs Gary, I'd chicken out too at those sorts of distances!
Are you sure it's phased out Robert? I can't find it in stock anywhere but I thought that was just due to demand, they're going for ~5x official price on eBay."

"Good stuff - I haven't yet bought a replacement controller for the same reason, Pixhawk too big and APM deprecated. I have been considering getting the PXFmini as a smaller and more capable system. I think the code should run fine on it."
"Hey Trung, unfortunately I didn't get much done last year. I was pretty busy with work and also managed to lose my Radian in a tree! I did compile for Pixhawk back in April, obviously this is slightly behind the main ArduPlane code now. I am hoping…"
"Nice one Thomas, that's useful. I do most of my calculation in Matlab but Excel is definitely more widespread and accessible. I have a spreadsheet at work for estimating the drag polar from test glides that I can add later in the week.
Cheers,
Sam"

"Hi Thomas,
Sounds like a nice day out! Windy and rainy here. Just to update your numbers after my mistake, your parameters would be:
Polar_K 16*0,850/0,24 = 56,7(sealevel)
Polar_CD0 = 0,041/(default) -> 0,045
PolarB = 0,033(default) 1,6*1,6/ 0,24…"

"I just realised I got the numbers for Cd0 and B the wrong way round in my previous post! I'll repost it here and delete the old one to avoid confusion.

"Hey Thomas,
Yes for finding the polar I do some glides at different airspeeds, work out lift and drag ratios and a best fit drag polar curve.
Looks like the release versions are marked by tags, so I should be able to merge in.
Sorry, that was an…"
