"Thanks Tommy. So I'm confused: if used properly these batteries are great, but yet no one is selling them anymore. Why were they pulled from the market? We shoudln't have to make our own lipos :)"

"Ok, Mark. I do agree the the videos are fun to watch and may have benifitted from some type stabilizing of gimbal on the fixed wing aircraft."

Burning Man in 4K resolution (day) and 2.7K (sunset/night) from a HK Sky Eye with pixhawk and ardupilot

A lot of work went into building this plane, adding redundancies and safeties, as well as fitting 3 cameras, and the result was well worth it. Big thanks to the ardupilot team, nightghost for his OSD firmware, and all the other folks who wrote some of the software the 5 computer/microcontrollers that were in the plane (not counting those on the camera or VTX):

Pixfalcon and Brotronics PowerTowerRX review for use in a 7 channel plane

Posted on July 12, 2016 at 10:30pm 4 Comments

Andrew recommended that I look at pixfalcon as a smaller pixhawk for some of my RC planes, so I got one for a bixler 2 build (he did recommend pixracer too, but that one has 6 PWM outputs instead of 8).

Here's my blog post on a bixler2 rebuild with a pixfalcon and Brotronics PowerTowerRX with backup lipo and buzzer:…

Cleaned up MinimOSD code, saved some bit, added real rotation switching

Posted on December 22, 2015 at 6:30pm 4 Comments

FPV cam

I had to hack on the code to fix rotation switching, and added instructions for others who want to build themselves since it took me a little bit to figure it out.

If you are using Plane, can you test this build to make sure I didn't break anything while removing dead code and cleaning all compilation warnings?…

Trying 3D FPV flying on a plane with wide angle 3D view (using skyzone 3D FPV goggles)

Posted on December 1, 2015 at 4:00pm 6 Comments

wide

I got to try the skyzone 3d fpv goggles after making my own wide 3D camera for my plane, and get to see 3D at a longer distance than normal. It's kind of cool :)

Too bad the skyzone goggles can only record 2D :-/ (so I have no cool 3D video to share).

Anyway, this is my review of the Skyzone SKY02 V3 AIO 3D FPV Goggles, which I got to supplement my Skyzone Dual Antenna FPV Goggle V2 on my blog: …
