My First Hexa Flight

Here is the first flight of my first hexa :D used software AC2.5.4 wich gave an excellent flight (I had 2 yaw twiches) Loiter still needing some work in software or PID. I think throttle rate is a bit higher causing those ups and downs. Alt hold seemed to work better with version 2.2. RTL worked pretty well and that option to disengage auto landing it's great.…

Flight Tests with Arducopter 2.x

This are the pictures from my first auto fly mode wich took place today. I was happy with the results even if alt must be tuned, but I had no crash, and any flight without a crash, for me is a good flight :D

I made 2 passes of the same path and as you can see there are some alt variations, the quad looked like a frog jumping from point to point.…
