"Hi Chad!
I had a problem like this with a differential pressure sensor a couple years age. Turns out the pressure sensing elements are very sensitive to sunlight. I had hooked up pressure probes to the sensor with transparent yellow, Tygon-like,…"

"Are the arms "pultruded" or woven carbon fiber? I've had pultruded lose torsional rigidity after a crash with no apparent loss of longitudinal strength. Longitudinal delamination of fibers allowed the motor to rotate very easily about the…"
"Randy, et.al., We are experiencing same rc3 issue. Lawnmower mode. :) Looked at drone discuss and gitter, cannot find the discussion. Note we are using Lidar Lite but not flow, we did not do the Lidar prearm because we thought it only applied to…"
"I've seen an issue wherein if you set the WP radius to 1 (I am working in units of feet and feet per second), save a flight plan, and then reload it, the MP resets it to zero when I reload it. If I try to fly the flight plan without checking that…"
"Randy, you are a busy guy... Many thanks!

"I am having same sonar scaling issue, sent Randy logs a week or so ago... He is busy! I can repost if it would help..."
"Never downloaded or sent a dataflash log before, hope this is correct! Also included logs from same short, low altitude auto mission. Advise issues, many thanks!2014-09-09 16-35-14 -1.log2014-09-09 16-39-24.log"
"Download over telemetry works fine for me, it is slow due to low baud rate, but it works!"
"Hi Randy
I got my MB1200 (EZ0?) to work yesterday using your reworked wiki instructions. Many thanks! The information in the MP appears to be inconsistent with the wiki, but the wiki steps worked and it's the first time I have been able to get…"

"Hi Randy! Just loaded -rc5, ran through all set up's, cals, etc., it arms normally and flies perfectly! Detailed testing and tuning commences... Thanks, sincerely great work!"
"Thanks Randy, tried to reply over iPhone, not sure if it worked, sorry if there is a duplicate message...
Yes, just checked again, it always arms via MP without LiPo, no warning messages.
I have since been able to get it to arm and fly twice (out…"

"I tried your suggestion, hold down safety switch when applying LiPo power. Did not work. So I tried it re-calibrate ESC all at once. Didn't work. So I tried all at once calibration, holding down safety switch with throttle up to start calibration.…"

"Alas, I have done both many times, but thank you! I have calibrated the ESC, per both the "all at once" and the "individual" procedures prior to flying with 3.1.5, and they worked normally, and it flies perfectly. I did not think they need to be…"
"Need some help with this one please...
- Load 3.1.5 (no cal, no wizard, nothing but software load...). Apply LiPo power, all ESC's beep: beeep-beeep-beeep - beep-beep - followed by single ongoing beep, all motors wiggle. Arms and flies normally.…"
