About Me:
I'm a 37 year old computer technician always eager to learn a bit more about anything regarding electronics and computers and space and ... women !!! (the last one even thoug impossible, I belive to be the last gold of any man)
Please tell us a bit about your UAS interest
well, not so far ago, I became interested in this matter, without knoing there was already so much acomplhisments in this area. I was fully unaware of the quadcopter existence and was at the virge of building my own first arducopter starting with nothing else than my arduino and accelerometers and a couple sensors more. Now I'm completelly hooked to this.

Well, I don't know if this was already posted but I've came across with it just now. It's a 2011 video, so probablly you have seen it allready, however it's really cool :D

Nice video for those who want to start and don't know the basics !

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

Posted on May 12, 2012 at 8:30am 5 Comments

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. Thanks…
