Arduplane without a compass?

Started this discussion. Last reply by wolfgang Sep 17, 2013. 3 Replies

Can I safely fly arduplane without a compass?  If yes, what won't work as well without a compass?  I have an APM 2.0 with a bad internal compass and it won't accept an external compass (even after…Continue

I just had my first stable loiter yesterday after running compasmot and it was very impressive.  Tuning wasn't very difficult for the most part and the biggest barrier we have with getting more helis…Continue

Chris Anderson on Marketplace

Kai Ryssdal with Marketplace went on site to meet with Chris Anderson at 3d Robotics to talk about drones. You can listen to the segment here. …


Measuring SWR (Standing Wave Ratio) on your antennas with a Daiwa CN-801

Posted on February 12, 2013 at 6:36pm 14 Comments

SWR is one of those things that most people don't need to worry about.  However, when you start building your own antennas or need to get every mw of power out of your existing antennas, you might need to check/tune your SWR.



FPV antennas: Building True R/C style circular polarized antennas.

Posted on December 8, 2012 at 7:00am 11 Comments

I assume most of us know that circular polarized antennas are great for FPV video streams because they're good at rejecting out of phase signals.  Thankfully you can buy these most of these antennas now, and even better yet, you can make your own with a little bit of work.

Probably the most popular design is the clover leaf, however I always hated…

hi Josh.. why no pics of your F450?? :)   I would love to share my APM config settings but I am not running APM at this time.. I run a Naza and a Wookong... I have been working 84 hour work weeks since March and so I figured I just didn't have time to mess around with APM just yet.. and I wanted to get to flying with as little free time as I have right now.

I've been changing so much (and will again when I get new base, I haven't bothered taking any yet).  Right now I'm the king of velco and zip-ties.

Do you have an OSD  with your current setup?  How's your video reception with the Y antenna?  What are you running for your ground station?  I see you having a beefy video TX there, I'm still running a 150 mw.
