"hi Mark:I also have an IRIS + (actually replacement IRIS+ from March 2015) and haven't had many GPS issues and my Hdop is typically low 1.4 to 1.7.  The caveat here is I usually have 9+ sat.  I like the idea of the GPS on the mast and may do this to…"

"I had the same issue with mine.  To solve the problem I used JB Weld.  its an automotive product, and hardens literally like a rock.  First I unscrewed the mount post from the Tx then used JBW to permanently keep it from unscrewing.   I had one…"

"Do not let up on 3d our customer service. Continue to hound them until they get you a new drone I was convinced absolutely 100 percent certain either my drone or in my case I believed the controller transmitter was faulty. You need to pay a…"

"As inexperienced as I am..I would respectfully disagree. The motors stopped and THEN the iris crashed. A low charge bat. Should trigger a low bat. Failsafe and land. The logs will tell."

"So sorry see that. The motors stopped. Did the battery door open and let the battery fall out or did it fall out after crashing. I feel your pain brother. I'm convinced my first iris was a lemon. My replacement hasn't had any issues. Please post…"

"Hi Justin, I'm traveling for a few days and fishing for a few days so if I don't respond right away that's why. As far as the time of the flight the actual log file name begins with the date and is followed by a series of numbers mostly separated by…"

"Hi Justin.  Not sure how your particular capacity controller works but you definitely NEED to read the instructions.  LiPo Batteries are truly great but not without risk. read about them and use the LiPo charger "bag"  So far I've not had any…"

"Hi Justin:
I am also on my second IRIS from 3dr after a number of disappointments and a bad crash.  I am happy to report that 3DR replaced my first drone at no cost, gimbal and all (this was a 60 day process).  This all happened  in March just…"

"Hi Forrest.

Sounds strangely similar to my flight. Up and down erratically.  like the motors power up and then down. my throttle was also un responsive.   Unfortunately, before my flight ended my IRIS had climbed to over 1000 feet and eventually…"

"Hi Kris:I think a "death" switch is a good idea.   I had my IRIS fly almost out of sight it was so high (1,100+ feet) .  Fortunately, I had pitch/roll/yaw so I could keep it overhead, but no throttle.  After a 300' plummet to earth, my IRIS is now…"

"Hi Heller.  Always good to have an exit plan.  
when you say calibrate it every time, do you mean the IRIS compass?  "

"No Worries about the spelling.   I'm not the "Church lady".   Excellent comments.  Know what you're doing without guessing...sooo critical when things are NOT going well.

definitely have to add "switches up" to my Tx checklist "
