Hi!
I just started with APM, having used KK for a couple of years. Thought I'd go crazy and build a Heavylift Hexa, but I mistakingly bought 9 motors instead of 6, so Octocopter it was! :)
This is from januari 5 2013, just after having done the autotune and setting the first PID to .09 as mentioned in the settings. Nothing else done basically.
I go a little crazy with the throttle at liftoff.... but I liftoff using only throttle. I can then release the sticks for long periods of time in Stabilize mode, and it will basicaly loiter in stabilize mode. :). Flying in stab during the whole video. I was unable to crash it although I tried giving it full stick forward and all directions, it just flew at a 45 deg angel, then when I let the sticks go, it levelled and stopped. Like a dream, I can't believe it!
If it stops raining I will try Loiter and RTL today.

My setup:
Hobbyking X930 Frame
Turnigy D3536-9 910kv 370W motors (x8)
Turnigy Plush 40 Amp ESC, not flashed or anything.
Hobbyking 6ch radio system. (The $22 one)
APM 2.5+ with 433 telemetry.
10x4.7 SF props, three different kinds, unbalanced, sloppily drilled from 3-6mm holes to 8mm holes.
(new better ones on order)
Turnigy Nanotech 4S 3300mAh batteries, 2 in parallell.
About 40 Amp to hover at about 30% of motor capacity. I had to make a throttle curve or it would hover at 5% stick...
To all the persons involved in APM: Thank you! I', glad I bought this and not a chinese knock-off, I want to contribute. Without you, no APM. I'd have to spend 10x more to get the same.

Magnus, what flight time are you seeing with that build and have you tried a payload, I want to build the exact same setup to carry a gimbal and camera but I also want to maximize flight time with a payload of about 2 to 3 kg.
Thanks,
Justin
