Hi, I just watched this video, and it seems to me a good ground base for those who want to start with multicopters and don't know what's the best platform.

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.…

The Relevance of Propellers

Hi again. Latelly I've been testing some different propellers on my quad and checking the main differences between them. For my emax gt 2218 930kv , my 3S batt and the 1500 / 1600 weight, I was using those cheap 12x4.5 props. I even bought 12 pairs for $25 or so, and one thing I can tell you about them... FORGET ABOUT IT. After 2 crashes from wich I could not tell if it was a motor or prop problem, I decided to test other props. I started thinking that too much flexibility would have a…

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.…
