"This is not true. There is a specific order these rotations are applied. In aero, it's usually yaw, pitch, then roll in that order. And this is true ONLY if you are going from air to ground coordinates. It's reversed for the other…"

Tj Bordelon replied to Juan Carlos Hdez's discussion sensors in the arms?"I wouldn't discount the idea. I had my IMU in a wingtip and the accelerometers worked. I bet as accels get lower in noise, you may start to get useful rotation data-- where one wingtip accelerates up and the other down. I think the idea is…"
Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"Right. But we were talking about how things should be I thought. Not how they are.
I think we've worn this thread out."
Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"Ok, I get it. Both of us agree that "this is the way it is", but you go along with it in principal while I don't. We also disagree on whether or not the govt has the "right" to do what they do. Fair enough."
Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"Why do you equate what I am saying with being stupid? Please re-read my posts.
We as a hobby should have no less right to use the sky than a major airline. So long as we are safe about it. The rules should allow everyone to use the sky. Where…"
Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"@Duane. If I want to ride my bike across the country I can. I just have to go on the sidestreets. If I want to fly to 100k feet for high altitude experiments, I CANNOT. Not in the desert, not over the ocean, not through some corridor, not with see…"
Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"@Duane - You have a common misunderstanding of the rights you have as an American. Seriously. It's not a God thing more than a logical operator. Let's try in C:

Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"@Duane - Go try to sell a UAV right now and expect your customers to operate it without hassle even though you are being totally safe. The fact that you can't shows me the FAA is stepping on my rights.
Also, judging by what…"
Tj Bordelon commented on Duane Brocious's blog post Community Based Organization Standards"@Duane - Small correction... According to my American History class way back, We have divine rights. These rights are given by "god" and not by the government. Note that this is the the founding principal of our country! And this is not…"
Riccardo Kuebler commented on Tj Bordelon's blog post Waiting to test new EZSTAR landing code!"Ciao Robert,
the FunCub is still in pure RC configuration (no AP on board), so no particularly interesting and a little OT here.
I still don't know if this will be devoted to that or if I leave it to have some pure simple fun.
If I will find a…"
robert bouwens commented on Tj Bordelon's blog post Waiting to test new EZSTAR landing code!"ciao riccardo,
it might be interesting to see some picts of your funcup.
installing the electronics is always interesting.
the funcup was sold during the last few weeks ... was thinking about getting one.
regards
robert"
Riccardo Kuebler commented on Tj Bordelon's blog post Waiting to test new EZSTAR landing code!"Hi TJ,
I just did the maiden flight (and some others, including glider tow) of a new FunCub. Pushing it at the limits I had a lot of fun, doing landings with flaps at 90° :
plane over head, throttle off, flaps full down, vertical dive (I mean…"

Tj Bordelon commented on Krzysztof Bosak's blog post A Milestone: single-button UAV for photomapping - The Pteryx"PS - What did you wind up using for your photo stitching if you don't mind sharing?"
Tj Bordelon commented on Krzysztof Bosak's blog post A Milestone: single-button UAV for photomapping - The Pteryx"@Krzysztof - Been watching your progress for a year or so. Congratulations! I have yet to really do much with my tech, and haven't really found anyone willing to take a risk here in the states given the regulatory situation. Did you partner up…"
Tj Bordelon commented on Gary Mortimer's blog post Very nice"Wasn't space 50k feet less than 100 years ago? Then they moved it to 50 miles. Now it's 62. Balloons reach what is commonly called "The edge of space" by the various groups. I like that title better."

FreeSpace Autopilot Crash!
Posted on October 18, 2010 at 6:30am 26 Comments 0 Likes
Toward the end of the video you can see the crash. The plane is trying to follow a runway beam but winds up oscillating back and forth and eventually tip stalls. The only thing that saved me from ending up on the roof of the barn was accidentally…

Successful reverse thrust landing in 28+ mph gusty wind
Posted on October 9, 2010 at 7:50pm 14 Comments 0 Likes
Ever fly on days you know you shouldn't? Trees were swaying, and my gut was saying no. But I guess you never know until you try. I'd have to say that I couldn't fly in this wind. The ground track of the aircraft was so unintuitive, especially on landing. At times it was just hoovering overhead making minimal progress.
Days like this that really test your autopilot.
Anyway, this video shows my full auto-landing sequence, complete with the dive from 180… Continue
Fried motors

Doomed flight is here:
Hobbypartz.com has great prices and great motors. I think. But for some reason I seem to be having some very bad luck frying motors lately.
I've been running one of their 450TH motors rated for 230 watts (http://www.hobbypartz.com/45oubrmo6.html) at exactly 230 watts, and haven't had much issue with very short bursts at the 230 figure of 40 seconds or less for… Continue
