Tim replied to Shane's discussion Arducopter just not reliable.
"Hi Bill,

Yes, I get that sunlight causes baro fluxuations. It seemed in Rob's post that he covered his PX4 baro quite well; at least as good as having a dark case? If in fact he did, and no light gets to it, then only the prop wash is left as the…"

Tim replied to Shane's discussion Arducopter just not reliable.
"Rob,

Don't both the Pixhawk and PX4 FMU have the same MEAS MS5611 baro? (According to the specs)

If so, it sounds like something else is going on other than just baro coverings? Doesn't seem like sunlight is the issue. Are the designs of you PX4…"

Tim replied to Shane's discussion Arducopter just not reliable.
"Rob,

Your PX4 baro comment caught my attention. You still have issues with the PX4 even after covering the baro/etc? I ask because I was just about to buy one for a mini build (Pixhawk is too large). If you still have issues even with your…"

Tim replied to Geert Pirens's discussion Crashed by initiate RTL (Return to Launch) when I was in mode Alt-Hold and did Autotune (help)
"If a GPS lock is available, "Home" is where the copter is armed, not just where/when powered up, which can be different if you move it around before flying like I do.

"RTL will command the copter to return to the home position, meaning that it will…"

Tim replied to Joe's discussion FS_TH9X
"It's very surprising a Tx would require the throttle to be 100% when turning it on. Normally, it's all switches back (away from operator) and throttle at zero, not max (for obvious reasons)."

Tim replied to Staq Koenig's discussion All motors stop suddenly with Pixhawk
"I'm not an expert on logs, but it looks like you had a motor or ESC failure, or burp. The following throttle in/out picture shows that Pixhawk suddenly increased throttle out in response to trying to keep the copter stable (while throttle in was…"

Tim replied to Patrick Roy's discussion ??What's the problem with 3dR responding to help/warranty e-mails??
"I figure I'll chime in. I've had to ping tech support and customer service a number of times over the past 4 months. I must say, they have always been responsive and very pleasant in doing so. Even the hand-offs between people have worked well. This…"

Tim replied to Kate's discussion Custom sensors and Real-Time logging
"Agreed that some documented sanctioned option should exist to access the analog pins outside of your, um, shortcut. In the meantime, your posts on this have been very useful. :-) - Tim"

Tim replied to Kate's discussion Custom sensors and Real-Time logging
"Good stuff James. Q: is this "how to" documented anywhere besides your posts? I've been building and reading the APM code for a few days and had no clue this existed. I would eventually have run across this in the code once I got to these files, but…"

Tim commented on Toby Lankford's blog post Happy 4th of July: May the FAA Give Us Our Independence
"Hopefully you were safe when acquiring the video. We had some mentally challenged person flying over the crowds in Vancouver BC to get their fireworks shots on Tuesday."

Tim replied to Nuno's discussion MISSION Planner Circle around a POI
"Ah! Your (old) post was my missing link as I was trying to decipher how my loiter_turns mission command was supposed to work (wasn't using ROI). My quad did indeed circle a phantom point that was directly ahead of it circle_radius away. For the life…"

Tim replied to Tim's discussion Pixhawk RCOUT Unbalance?
"I wonder if the motor RCOUT differences are the result of some tuning that APM does as it observes stable flight? e.g., adds in known trims of some sort. In my case, I know my quad is weight biased to the rear a little (because that's where 3DR put…"

I'm running a 2014 RTF 3DR Quad with 3.12 (yea, I've been told to upgrade).I noticed yesterday that in stable hover on a windless day, my motor (RCOUT) outs are not the same. The logs clearly shows that motors 1 and 4 are sort of in sync while 2…

Tim replied to Camille Goudeseune's discussion Breakaway GPS mast for 3DR Y6 and X8?
"My 3DR mast broke at the pivot my first flight. I simply removed the pin and mast sleeve and superglued the mast against the back of the mast base where it normally sits. A flip sheers off the superglue. I glue it back on and I'm good to go. I've…"

Tim replied to Tim's discussion Pixhawk Vibrations Log Wrong?
"Hi Craig, thanks for responding.

According to MP 1.3.5 I'm running 3.1.2; which is what was loaded when I received the RTF.

My concern is simply that it's too good knowing that I only semi-balanced the props, and when compared to 90% of the other…"

I got my 3DR 2014 RTF Quad a couple months ago and have been flying/crashing it ever since.  :-)My first logs, sans prop balancing, showed high vibrations (so much for "RTF"). In hindsight, that was probably expected since I didn't balance the…
