"The motor would only be doing what the throttle stick is telling them to do. Take out any expo or curve in your tx, then recalibrate your radio and also the ESC's again. This should match the throttle position to the ESC's. Calibration the…"

Peter Arnold replied to Mert's discussion Quadcopter nose dive on first flight in the group ArduCopter User Group
"Sounds a frustrating start but I have been there! If your props started spinning immediately it could mean the ESC's need calibrating and it may play to redo the radio calibration again. For the nose dive check the motors are plugged into the…"

"I have the same frame with 4016 380Kv motors. 16 Amp Bat. Pixhawk.  Some issues :   RC_FEEL_RP = 50 is overpower, try 45-48 PID: After auto tuning the multi is very responsive, lower P value will make it smoother.  Take off:…"

"At 8 kgs the calculator gives  Hover Thrust = 11,220 g  Maximum Thrust = 21,120 g  Peak Efficiency = 12.857 g/W Being 2 Kgs lighter would make it a bit more sensitive?"

"Hi Justin. Good question. The present weight is 6 Kg and but with the camera gear it will be about 8 kgs. Using the KDE calculator and 8 kgs they recommend the KDE 3510XF 475 motors. which is what I have. At the present weight of 6 kgs it is a…"

"What's your thrust to weight ratio? First have to determine if you have an over or underpowered quad."

"Thanks for the further information! I had RC_FEEL_RP set at 50 just as a starting point and will try and do some in flight tuning.Maybe work my way up towards 11 bit by bit. However I'm a bit confused about the Inflight Tuning. It says…"

Clifton Hipsher replied to Peter Arnold's discussion Pixhawk Hex Take Off Stability problems in the group PIXHAWK
"Some other things that can jump up and bite you: 1.  RC_FEEL_RP, particularly when the aircraft is overpowered (hovers below 50% throttle). 2.  Autotune.  I prefer using In Flight Tuning.  I ran AutoTune on a quad that was…"

"Hard to tell if the values are to high (creating oscillation) or to low (inadequate reaction from the controller). When I was getting off the ground I adjusted stabilized roll and pitch no more than 1.0 for each attempt.  Try upping the values…"

"Peter, I have an 850mm quad with Pixhawk.  Two things come to mind.  One, I agree with Clifton.  "pilot's first mistake is trying to level the rotor disk before he takes off,  Because the airframe is still on the ground…"
