John C. commented on John C.'s blog post Cheap Fixed Wing Mapping
"Your comments are spot on HDP.
1) I'm flying at sea level in ideal temperature conditions.

John C. commented on John C.'s blog post Cheap Fixed Wing Mapping
"I've flown 120g on it with no problems. I'm sure it can take more with the stock power system.

APM is a more stable experience in AUTO. I've used the FreeFlight app to plan a lawnmower pattern, and the Parrot flight stack was giving me 90deg roll…"

"Ten thousand dollars?!?! It's just a piece of foam!"If you've uttered those words, this post is for you.We will not debate the value of quality or workflow simplicity contained in that $10,000. What we will do is demonstrate how to make a "cheap"…

"Just thought I'd share a little video I shot from a Disco.  https://www.youtube.com/watch?v=6ZiUJ0JaCY8

Video quality is even better in the production version. I have a biased view, but for anyone that wanted to learn about fixed wing or just loves…"

"@James - correct, it requires 5V at 2.4A I used a BEC.

@Troy - I'm going to try and do the S100NIR next to Sequoia next week. I'm not sure how SenseFly is handling the eBee field upgrades. I'll ask.

@Leo - There is someone working on the Pixhawk…"

"I'm not sure what the minimum focal distance is but, yes, you can definitely use this in your hand, on a ground based vehicle, or on a pole!

"@Dries - Yes, I believe that offset is common in any multi-sensor solution. There's some kind of physical offset that you have to account for in the image alignment. Pix4D does handle that correction in the new "Camera Rig" feature from my…"
