What does the red arrow mean in Flight Data screen map?

Didn't find documentation for this. In the attachment, there is no arrow, but once flying, it changes to arrow and the number grows.

Auto Analysis doesn't work?

(different from http://diydrones.com/forum/topics/auto-analysis-may-not-be-functional-in-mp-v1-3-27)

Whenever I try to use the Auto Analysis in Mission Planner (tried 1.3.27, 1.3.27.1 and whatever comes before 1.3.27) the Planner immediately goes into

Adjusting turn rates? (confused about parameters)

Powering Pixhawk + other stuff

Hi,

Are there any best practices when using additional BEC to power servos and peripherals? Am I good to go with the attached diagram? I will be powering Flytron strobes with the BEC also, which isn't yet on the picture. They will draw 1A each per fla

Fixed wing output wiring / config question

Hi,

This must be a stupid question, but I'm a bit lost trying to understand Pixhawk outputs. From what I've gathered, Pixhawk doesn't provide power to the servo rail, so I will have to provide power from ESC or BEC. Simple enough. But when I read the

It's been a few years, what's new?

Checklist

Hello,

Could some wise and nice individual go through my list of items I plan on ordering and check for anything that might be missing or otherwise incorrect. I would hate to notice that I miss a crucial connector or part while almost finished build

Arducopter 3DR?

Hi,

Just stumbled upon the Arducopter 3DR frame and now I'm confused. I was about to buy the Arducopter Quad kit as suggested by the wiki, but now I need to put that on hold until I get a few answers :)

1. Is this a new version of the frame and will i

Few questions before order

Hello!

I just discovered the world of UAV’s few weeks ago and got really intrigued by the idea. Found DIYDrones and thought this would probably be the best place for a newbie such as myself to start out, since there seems to be good documentation and
