Doug Ellison commented on Julian's blog post 3DR's Rise and Fall
"The reason is fairly clear to me.   The Iris and Iris+ were very poor products, and tech support didn't match their poor failure rate.  They were dangerously underperformant for their own weight, let alone the weight of a payload.   Thus sales were…"

Doug Ellison replied to Todd's discussion New GoPro Lens vs Cannon CHDK for mapping in IRIS
"They looked at tlogs and told me not to fly my S100 under my Iris+ as it was too heavy.   That's what they said.

I was using the KAP-UAV script - and never, not once, could I get consistent un-blury photos.  I wasted days trying - and there's many…"

Doug Ellison replied to Todd's discussion New GoPro Lens vs Cannon CHDK for mapping in IRIS
"Don't believe the '500g' payload claim for the Iris+     I was flying a 200g Canon Powershot S100 - and was told by 3DR after it crashed that the reason it crashed was I was carrying too much weight.   Iris+ is marginal on performance as it is...the…"

Doug Ellison replied to Todd's discussion New GoPro Lens vs Cannon CHDK for mapping in IRIS
"I tried a Powershot S100.... and the Iris+, on multiple occasions, couldn't handle the weight and just crashed.  3DR told me that it was too heavy.  The GPS from the S100 was unreliable anyway. It wasn't worth the hassle - so many photos would be…"

Doug Ellison commented on Andy Jensen's blog post Last-sell for many legacy 3DR product
"It would be a lot easier to find what's actually for sale, if all the 'out of stock' items in clearance would go away, and you could filter by platform."

Doug Ellison replied to David Gwenzi's discussion No GPS time in flight log file
"I have the same problem with my Iris+.   log_bitmask is set to 6535.  Mission Planner can happily generate an accurate KMZ file from the DataFlash log.  The TLogs from my Nexus 6 in flight have time stamps - but the DataFlash file does not....and so…"

Doug Ellison commented on lianpinkoh's blog post Simple 3D-printed CoG mount for Iris+ to carry a mapping camera
"I tried something similar with a Powershot S100 - and 2/3rds of the images were unusably fuzzy."

Doug Ellison replied to Justin Ackermann's discussion Iris+ Random Crash In Flight - Lost In Water in IRIS
"I sent logs, and they told me to never flight that configuration again ( carrying a payload LIGHTER than the one they'll sell you themselves ) - and then sent a replacement ESC anyway.   A contradictory stance.  I've not bothered this time yet.  I…"

Doug Ellison replied to Justin Ackermann's discussion Iris+ Random Crash In Flight - Lost In Water in IRIS
"I've had the same thing now 3 times with my Iris+   

The first time it suddenly starting dropping altitude and ended up with a hard crash that destroyed a Powershot S100.  3DR claimed the S100 was too heavy for the Iris+...which is untrue - it's…"

Doug Ellison replied to atomz's discussion Canon SX260 HS Altitude Errors
"3DR say a probable failed 4-in-1 ESC on my Iris+ - so they're sending me a new one....bit of soldering and I'm sure I'll be back in the air. "

Doug Ellison replied to atomz's discussion Canon SX260 HS Altitude Errors
"I was flying a Powershot S100 under my Iris+  (until a crash killed it) and found that it always struggled to get good GPS lock - simply because there's a great big Iris+ directly above it blocked the sky and thus its view of the satellites.   Best…"

Doug Ellison commented on Mustafa TULU's blog post USA Trip Canceled
"Agreed. I think Trent and the team did pretty well to even get that far. I backed his IndieGoGo campaign, and I'd do it again in a heart beat!!! They tried hard, but stopped at the right point. Here's to trying again!!"

Doug Ellison commented on Nicholas Witham's blog post Game of Clones...........
"Rob - you might be able to make a moral case if 3DR itself had not just contributed to, but also heavily benefited from the open source nature of the platforms involved.  People not paid by 3DR contribute to their code - and in doing so improve the…"

Doug Ellison commented on AKRCGUY's blog post More Amazing Rocket Footage Shot From Multirotor
"Jani - fins?  You mean the landing legs? CF and Al honeycomb.  They deploy out from the side of the 1st stage after it's launched.  In this test, obviously, they're pre-deployed."

Doug Ellison commented on AKRCGUY's blog post More Amazing Rocket Footage Shot From Multirotor
"Robert - this isn't a launch pad. It's just a testing landing pad for tests of this nature.  They have launch facilities at CCAFS at KSC ( one pad in use, one ex-Shuttle pad just leased for 20 years ), VAFB, Kwajalein Atoll, and there is talk of a…"

Doug Ellison commented on Nicholas Witham's blog post Game of Clones...........
"I ordered a RTFhawk 2.4.3 from them a week ago.  No updates since. No reply to my emails asking when it might dispatch.   Not sure what 'reputable' means these days, but I don't think it's that."
