Peter Arnold replied to Mert's discussion Quadcopter nose dive on first flight in ArduCopter User Group
"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 ESC's can…"

Peter Arnold replied to Mert's discussion Quadcopter nose dive on first flight in 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 PH in…"

Peter Arnold replied to Peter Arnold's discussion Pixhawk Hex Take Off Stability problems in PIXHAWK
"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?"

"Thanks for the replies! 
I'm confident the accelerometer calibration is OK and when it is in the air it flies well and is very stable. I have done a auto tune but later wound the P back hoping it would fix the take off problem. 
Clifton may have…"

Hi.I am having major stability problems on takeoff with my Pixhawk controlled Tarot 810 Hex. If I try and take off smoothly and slowly it starts wobbling and will usually flip onto its side. If I get it to leap into the air by applying the throttle…

Peter Arnold replied to Tom Moore's discussion Pixhawk quad crash - help analysing logs in PIXHAWK
"I think he is also asking for some help on reading and analysing the logs. Information on how to graph the log files is difficult to find and understand. I for one would like to find some information how to use the log graphs!"

Peter Arnold replied to Peter Arnold's discussion Totally Confused. Help??
"Thanks for the log suggestion which I will use! I eventually got it working after reseating the gps cables which allowed a gps lock on.  As a guess the flight modes need a gps lock before arming??  There is a lot to learn but getting there. Thanks…"
