"Hi Wofgang
It has been a while.  I hope everything is going well with you. 
Are you no longer working with the X8?  We are still using the X8 with good success.  Take a look at our website for examples of all the work we have completed with the X8. …"

"Hi Everyone,
I am still in communication with Lehmann Aviation and my continual pressure (into my 3rd year) and postings on the internet have bore some fruit.  Lehmann Aviation and I have come to an agreement to refund 50% of my purchase price and I…"

"Hi Everyone,
Here are the developments on the carbon fiber under body for the X8.  Cleaned up the mold and waxed it to fill in some blemishes.  I had no idea what I was doing with the carbon, Kevlar, or epoxy so I guessed my way through it with help…"

"Hi Everyone,
It must be winter as I don't see too much activity on the blog.  It will be spring here in Northern BC soon and we are itching to get out and do some more flying.
We want to get the top heaviness out of the X8 to improve performance. …"

"Hi Michael,
Is it possible to get Mission Planner to log the XYZ roll pitch yaw when the camera trigger is activated?  Each camera and trigger are different so there would also be a need for a method to add a delay so those values are collected as…"

"Hi Tony,
It took Lehmann almost 6 months to deliver my first plane and it did not work.  It has been over 18 months now since I ordered my planes and I still don't have a working aircraft.  I would be happy with a refund but I don't see how I can…"

"Hi Tony,
I have made contact with Lehmann and he is promising to fix my issues.  I will give him another chance and if I get no results I will gladly supply you with all of my correspondence.  Please keep in touch and let me know how things are…"

"Hi Sgt Ric,  Thanks for the support.  All Lehmann Aviation has to do is supply me with what was promised and I will overlook the last 2 years of frustration.  This is the first of many posts I will be making across the internet until my issue is…"

"Hi Everyone,
I want everyone to know that Benjamin Lehmann of Lehmann Aviation is a fraud and a liar.  I paid him close to $16,000 for two LP960 systems almost 2 years ago and he has never supplied me with a working system.  I have over 100 email of…"

"Hi Everyone,
Here are a couple of orthos produced from our X8 platform.  The large photo ended up using 2327 images with a final GSD of 7.5 cm.  The accuracies in the XY of the orthophoto were roughly 15cm in relation to the true geographical…"

"I forgot to mention that there is also Agisoft PhotoScan which is only a couple thousand dollars but we have never had any success using this software.

"Hi Mariusz,

The most inexpensive software I know of that does a pretty decent job is AreoHawk which costs about $5,000 USD.  You can also use a cloud service such as Pix4D (I don't think they are very good) or EnsoMosaic which is a bit better.  I…"

"Hi Everyone,
 
I have been following everyone's posts and it is great to see lots of people out there creating their own platforms.
Have not been here in a while as I have been bus with my X8 development.  Gave up on the Maja as an aerial platform…"

"Hi Bret,

I am sorry but I cannot talk too much about our software at this point.  There is lots of competition in this area recently and we cannot show our hand just yet.  I can say that we are doing far more than photo stitching.  We are doing…"
