John Oberholtzer replied to John Oberholtzer's discussion Pilot Erorr/Solo Error? in 3DR SOLO
"Thanks again Paul, 
3dr support just got back to me and confirmed your analysis.  They also reported a motor failure:

John,
Seem that one incident was caused due to a GPS glitch, I recommend you upgrade to the new version as it fixes the bugs in…"

John Oberholtzer replied to John Oberholtzer's discussion Pilot Erorr/Solo Error? in 3DR SOLO
"Hello Paul,
Thank you so much for responding. You have provided more information in your response than I have been able to get out of 3dr in a week!
I did figure out how to get the solo.tlog.2 file loaded into Mission Planner.  Do you then have to…"

John Oberholtzer replied to Ken Nelson's discussion Solo Crash on Camera Flash in 3DR SOLO
"One of the reasons to implement a Kalman filter, or EFK, is to integrate all of your position data (GPS, accelerator, barometer)  and filter out erratic data.  In your scenario #2, if you lose a GPS sat or one of the sats gives bogus data, it should…"

John Oberholtzer replied to Gregg's discussion Yes or no to Solo in 3DR SOLO
"Solo App -> Solo Flight school -> First Flight.  At the 2 minute mark, Colin Guinn has Solo in hover and says Solo will stay within a 6 foot bubble.  I take this to mean +/- 3 feet in the X, Y, Z position."

"Hello Phillip,
Thank you for the response and information.  
I'm taking stabs in the dark while I await 3dr to get back to me on the incident posted in http://diydrones.com/group/solo/forum/topics/pilot-erorr-solo-error"

"Please don't get me wrong, I have no doubt that clever and qualified people are writing the code. 
I'm just basing this observation on my personnel experience between my Phantom and Solo.  My Phantom, in GPS hold, seems to drift alot initially.…"

John Oberholtzer replied to Ken Nelson's discussion Solo Crash on Camera Flash in 3DR SOLO
"Way back a long time ago, I did software engineering work with GPS and avionics systems for corporate jets.  We had to incorporate things like Kalman filters into our systems to prevent some of the same issues that Solo is encountering. 
From the…"

John Oberholtzer replied to Kelly Schrock's discussion Solo Log files: How to read them in 3DR SOLO
"I'm so happy that you brought this issue up.  The time that it takes to download log files from Solo, and my Y6, is insane.  
I had to file a ticket with 3dr (which has been a week and I'm still waiting to hear from 3dr, but that is another issue)…"

John Oberholtzer replied to John Oberholtzer's discussion Pilot Erorr/Solo Error? in 3DR SOLO
"I posted on the other thread with the camera flash.  The way that Solo took off looked very similar. 
I have heard that there is a firmware update that is supposed to correct the GPS issue. 
It has been 4 days since I filed a ticket with 3DR and…"

John Oberholtzer posted a discussion in 3DR SOLO
On the 20th of June I encountered what I believe is a Solo fly away and I posted a video in the 'Solo Crash on Camera Flash' post. I'm looking for some feedback and would greatly appreciate any help with this issue to determine if it was pilot error…

John Oberholtzer replied to Gregg's discussion Yes or no to Solo in 3DR SOLO
"My bottom line, no.
Long story short, when Solo works properly it is a great platform.
Unfortunately, about 50% of the time my Sole has problems acquiring proper GPS signal.  It is hit and miss, sometimes GPS is acquired in a minute and sometimes I…"

John Oberholtzer replied to Ken Nelson's discussion Solo Crash on Camera Flash in 3DR SOLO
"I've had that happen twice now.  In the last incident, I started Solo motors and then hit 'fly' to to auto take off.  I Once Solo was in a hover, I think I hit the 'fly' button and Solo took off and ran into side of house.  Video…"

John Oberholtzer replied to John Oberholtzer's discussion Solo Initial flights in 3DR SOLO
"No gimbal yet, GoPro in stock Solo mount.  The Solo seems to hold alt better than my Y6 in hover.  The Solo controller has a 'Pause Solo' button that puts Solo into Loiter mode.  I was getting a bit cocky after a couple of flights, pure operator…"
