"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…"

"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…"

"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…"

"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.

"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)."

"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…"

"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"

"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…"

"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…"

"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…"

"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…"

"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…"
