"I have not fixed the problem yet as i have taken a break from this project."

"I have since set the battery monitor using the wizard and set the parameter to voltage and current. I also made sure the battery was charged.
I have also tried tuning the PID's to lower values (initially 1.5 then 0.8 , 0.4, 0.2) for roll and pitch…"

"I'm having a weird issue. When I try the experiment you want me to do (left, right, down, up). The quad makes 2 log file for the flight. One always larger than the other. In the larger one there are no RCIN values (even though the quad is responding…"

"I'm sorry for the wait. I fixed the no logging problem by formatting the sd card and i setting the log maskbit from nearlyall to nearlyall+ AC315.

Here is my log of the test (set throttle to 50% and rotate the quad to its sides…"

"I'm currently having trouble with logs. The arducopter does not log any of the flights. I have reinstalled the firmware (3.2 arducopter) after installing arduplane to remove older data. This makes it log the first flight (with missing data such as…"

"It took all day but I finally got a log file. I think it was 3.2 causing the logging to bug. Switching to 3.1 fixed my logging issues (I think). 
So in the course of the day I rechecked the motors and re calibrated the quad. Unfortunately, the quad…"

Liban O replied to Liban O's discussion Quadcopter flips on liftoff
"I'm having issues getting the quad to log. i've tried multiple "flights" with no props and it will not log any of them. Is there a specific way of logging that i'm missing (logging worked this morning).
I've checked the params and it's set to log…"

"I also noticed that the roll is off by 0.4 and pitch is off by 0.15. I tried to do the calibration multiple times but could not figured out how to do it perfectly."

"Here is a video demonstration of the motors.

Armed and spinning at about 10% throttle.

"Here is a more recent log of this morning. RCIN values are looking normal now, i do not know why they weren't there before.2014-12-01 11-15-12 1.bin.log"

Liban O replied to Liban O's discussion Quadcopter flips on liftoff
"I tried looking at the logs and the RCIN's are all 0 (don't know why). RCOUT has values that look like what my quad is receiving.
The min for my rc controller is 975 and the max is 1980. I made sure to make sure all sticks were at their mid (except…"

"I checked the Motor configuration but I did not do a hand test. I will check the motor configuration again and  perform the test on monday (Quad is not with me). Thank you."

Liban O replied to Liban O's discussion Quadcopter flips on liftoff
"For the quad, we are using a simple breakout cable. I don't think this could cause the problem.
As for controls, the flips occur with only throttle. Even after assuring that the sticks were centered with calibrating the rc inputs and calculating…"

Hi,I've seen multiple threads about this topic and have tried most (if not all) documented fixes for this problem.I build a quadcopter using these parts:Pixhawk Advanced AutopilotUblox Neo-7M GPS with Compass (not connected)DT750 Hextronic Outrunner…
