Hi everyone,
I'm creating this thread to share your drone/copter information. I believe, this would help immensely for newbies like me during the initial build. For example, the Chris's blog on cheap Hobby King quad configuration is really a good resource.
I don't want to burden anyone who is willing to share their info. Hence all fields are optional. Atleast the first 5 fields are ideal. Please find the list of fields to copy/paste at the end, so you can start filling :-).
Here goes information about my quad.
frame: Quadcopter (3DRobotics)
controller/autopilot: APM1
esc: 20A (3DRobotics)
motors: 850Kv (3DRobotics)
propellers: 10x47, APC (3DRobotics)
motor to motor distance: -- inches
battery: 4S 3300mAh (Turnigy nano-tech)
total weight: -- lbs
flying time: 15 minutes (average)
radio: Turnigy 9X
video/osd: none
other: Sonar, Xbee, GPS/Mag, Attopilot current sensor
Misc:

To help we will need a lot more info than 'it won't take off'
What motors, batteries, frame weight, props, calibrations done, version of APMCopter, and maybe a photo or 2.
The more info you put in your post the more someone can help.
If you use Static Thrust Calculator
http://personal.osi.hu/fuzesisz/strc_eng/
you can input values for motors and propellers. It will help you calculate the lifting force the motors can manage. With this and the weight of the complete quad you can figure out if it can lift or not.
You'll want a lifting force more than double of the weight of your quad.
By connecting one of the ESCs directly to the receiver you should be able to run the motor manually. This can also help when measuring the force the motor + propeller can give you.
When I calculated my huge octo I fixated one motor on a table and put a scale under the leg of the table. When running the motor at full speed I could see the force difference on the scale.
There are many simple tricks you can do to solve the issue!
Good luck!

This is my Onago drone:
I recently bought AeroSky C6 Carbon 6 Channel RC Drone with GPS.
Waaaouw! You guys really know how to build nice Drones! :)
Thanks for many good ideas..

I'm still working on it, testing and fine tuning everything. Did a few test flights, chipped off a few rotor tips but flies pretty good.
Hi Folks
Here's my second build, canibalized from the first:
Frame iDeaFly 4S
Lid by OMG
Motors: SunnySky 980Kv 10X 4.7 APC props
Escs: EMax 20A Simon K
5000Ma 30C 3S LiPo
FC: APM 2.6, FW 3.2.1
OSDMinim bridged (5V only) powered by seperate 5V Ubec
3DR Telemetry with 1/2 wave dipole antenna with ground station connected to Bluetooth module
and Galaxy Note 3
Fatshark 600Mw Video Tx and Predator II goggles
Immersion CP antennae on both
HK 7" transmitter mounted monitor (Tarot bracket for Futaba)
Tarot 2D gimbal Go Pro 3+
TG 9X transmitter flashed Open 9X
FrSky Djt module with D8R-II flashed XP for CPPM
I like this frame for its ability to be folded/ reconfigured for an asymetric form. Currently quad asymetric.
A bit heavy I guess, bit flies really well even in our windy conditions! (Cape Town)
