I have a nice big grin on my face...I maidened my first Quad based on ArduCopter2 today. It flew pretty well out of the box using default parameters...a little wobbly but nothing that I don't think I can tweak away when I get my kids to bed...and the rain stops... :)

I did equip my old tricopter (now dismantled and donated parts to the quad...) with AC2 and it flew very well also. I felt like AC2 was really nice and I decided to invest in a Quad.

Anyway, I thought I could share my setup:

1 frame (from www.dyi.nu, Swedish site...please ask me if you need more info/translations)

4 Turnigy 800kv (2213N) motors 

4 ESC HobbyKing SS 18-20A

1 Homemade Power Distribution board (between frame an box)

1 Lunchbox (i.e. my canopy...)

1 ArduPilot Mega + IMU + compass (from diydrones.com)

Running on 3S, 2.65Ah Nano-tech

I have attached some pictures of it. Please let me know what you think of it...

Anyway...thanx to all involved in ArduCopter, ArduPilot, APM, ... You're doing a nice job! I hope I can contribute a little as I am a SW developer (embedded systems) myself soon. Time will tell...

Regards

Stefan
