About Me:

Flying Ardupilot since 2011 with APM 1 on my first quad! Don't get to fly as much as I'd like as space is a commodity in LA


Please tell us a bit about your UAV interest

Aerospace engineer and pilot, so naturally I love tinkering with this stuff and just making cool things happen!

Colin replied to Colin's discussion Crash in stabilize while hovering!
"Haha, hold on hold on, give me credit where credit is due! I said it looked mechanical first, I didn't jump straight to blaming the code! And I said rebuilding trust in the system, not just the ardupilot code!

I'm getting pretty frustrated with not…"

Hi guys,I rolled back to 3.1 because I was sick of my crafts (2 3dr quads) flipping in the middle of auto missions for what seem to be no reason. That was the only time I saw a problem with them.Anyway, I was just hovering while doing a 90 degree…

Colin replied to Colin's discussion Unexplained flip and crash in auto mode
"Oh no! It's happened again!

Checked all mechanical connections on the craft with everything looking good. I flew it 5 ft off of the ground in a gentle back and forth covering about 10 ft horizontally for a full battery in loiter mode. Then I gave…"

"I ran compassmot and it says 21% when I was just above cruise throttle. Looks like that's well within the suggested values. "

Colin replied to Colin's discussion Unexplained flip and crash in auto mode
"Thanks for checking! I just started reconfiguring my craft a bit today, so I can't check my compassmot values just yet, but will do, thanks. I do have the external mag on the 3dr gps/mag so hopefully interference isn't the issue!

I'll check and…"

Colin commented on Hansaka Perera's blog post Upside down quadcopter descend saved by flip. near fatal crash
"Hmmm, bummer. Sounds like ours are unrelated. I'm aware of instability with descent through propwash though. I was in auto mode and the two waypoints it was between were at the same altitude. The search continues for me!

Glad you caught yours! It…"

Colin commented on Hansaka Perera's blog post Upside down quadcopter descend saved by flip. near fatal crash
"Any idea what caused the initial roll over? This happened to me and I have a post up looking for help identifying what happened. Mine rolled 2.5 times before stabilizing upside down! No flip on hand, but thankfully it landed in a tree so nothing…"

Colin replied to Colin's discussion Unexplained flip and crash in auto mode
"Ah, it should be noted that this was a relatively new craft. I've flown about 45 hours with the exact same set up, so I got a second one. This is the second one. It's been through my rigorous flight test regimen and completed 4 auto flights before…"

Hi all,While doing an auto flight at 400 ft yesterday in 7mph winds, the craft took a tumble! Remarkably, it landed gently in a tree with only two props broken.Looking at the logs, I can't find any anomalies. I thought maybe it's was hardware, but…

"Very cool!
Have you got a link to the kickstarter project or the videos or something?

Maybe this would be a blog post but I suspect many people here already know about this.Quad fail safeHow hard would it be to get in touch with the FMA team and get this implemented into some of the arducopter code asap?I realize this is the type of…

Hi there,I just updated from 1.2.86 to 1.2.88 and it seems they've changed how the ground coverage is calculated. At 60m with my old camera I'd get pretty darn close to 1.9 cm/pixel according to my calcs, the 1.2.86 calcs, and my photos I was…

Hi there,I'm wondering if there is a setting for my flight paths such that my quad will maintain takeoff orientation throughout the whole flight. I'm trying to use DO_SET_CAMERA_DIST for aerial surveying, but about half of the time, I capture pics…

Hi all!I've been using my ardupilot for some surveying missions recently and I love the auto stuff programmed in!I wanted to try to make a multi flight trip today though so I was building flight plans and after I saved the first one with 184 way…
