I finally worked up the balls to fly the thing!
Im quite impressed that it actually flew and didnt just explode on the spot after arming the motors ;)
A little wobbly, but thats more me and the shaking than anything else.
Slight drifting, however I havent done the whole in flight leveling thing.
Firmware 2.2b2 Octa. Default PIDS.
So need to tune them! Any Octo guys have some pid suggestions? (What should I change?)
Im definitely looking for sluggish movement for taking photos/videos. I dont need any aerobatics.
As far as power goes, the whole time, i wasnt using more than a 1/4 throttle, even for lift off.
It did bob up and down a bit, thats also coz my TX throttle is a little stiff...
Yaw was perfect :)
All in all, it was a successful test flight! Especially since the last thing i built and flew was the
arducopter. Going from something that weighs 1.5kg with +-3kg of thrust.
To a MONSTER that weighs 4.7kgs with +-20kgs of thrust, is quite intimidating to say the least!
This is definitely a testiment to my engenuity, and most of all an absolutely SUPERB autopilot!
Next job, PID tuning!
Till then!

@Anish: Specs are here:

If you want frame dimensions, just shout :)
@Ellison: I managed to cut myself bleeding last night on one of the props. And all I did was walk past and bump my hand on in. Karlas always got some or other wise crack going ;)
@bmarshall: In theory should be able to lift 10kg. (perhaps a rocket launcher or paintball gun) >:)
The thing dangling was a lipo monitor. I had the tm1000 telemetry connected, so I just wanted to compare voltages between the two.

Great first flight, looks like you've started to tamed the monster. You should be able to lift a big payload!
What was that dangling from the copter and swinging back and forth? I could tell from the sound of the motors you were not using much power.
btw keen to know ur specs, esc,motor, props, frame, battery :)
Nice. It must be scary with all those ginsu blades spinning. ;-)
I like the wife, in the background, as the voice of reason, "Don't get too brave."
Will do :) Thanks guys!
Let you know how it goes tomorrow!
I agree with Russell. Lower your P_stab on both pitch and roll. I use around 2.8 for an octo that has a wider span than yours.
