Paul Barsamian commented on F. C. Bearsch's blog post Rethinking the RC "Controller TX" - SuperMan FM Continued-
"Interested to see how this turns out.  As a long time RC pilot (sponsored for a while) I'm having trouble visualizing how to have fine enough control for all actions in one hand simultaneously (lots of work for that particular hand to manage in live…"

Paul Barsamian replied to Benjamin Meltzer's discussion NIR Camera vs RGB Camera Conversion in Agricultural UAVs
"I've been having good luck with Tetracam, if you don't need the ability to change lenses I highly recommend the ADC Micro (not the snap as you pay more for quicker shooting but lower res images).  Also worth looking into is the set of sensors…"

Paul Barsamian replied to Paul Barsamian's discussion Pixhawk and 10s Power module from HK
"In retrospect, yes I think my xt60 connectors were backwards because I based my new plugs on where the old ones were, not looking at the end which the 6 wire connector comes out of which is a much more reliable indicator. I'm using Pixhawk/apm power…"

Paul Barsamian replied to Paul Barsamian's discussion Pixhawk and 10s Power module from HK
"Update: problem found.

"Guys, still ran into the "wanting to run away" issues.  I changed out my ublox for another one to test.  then I did a bit of interesting testing I thought I'd share.
 
1) Setup and turned on the Ion (remember this is a trad heli) and sat it with the…"

Paul Barsamian replied to Randy's discussion AC 2.9.1 vs 2.8.1 GPS accuracy
"Ran three packs today, GPS in MUCH better shape, now I just have to fix my declination and yaw issues. The config file you sent Stephen seems to work well, no jumping around. I'll test it on my trad Heli as well and confirm. I did also add a ground…"

Paul Barsamian replied to Randy's discussion AC 2.9.1 vs 2.8.1 GPS accuracy
"Guys don't know if this helps:
 
On machine 1 (trad heli)  I noticed the jumping behavior on a newly installed APM 2.5/Ublox and sort of resolved it with a ground plane plate below the GPS unit. 
 
On machine 2 (hexa) I recently upgraded from an APM…"
