"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…"

"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…"

"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 bit…"

"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 to Set the…"

"Harry
After the autotune I ended up with the following

I           0.3476464

"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…"

"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!"

"Thanks Craig.I am after some 6 strand flat cable but will take a look at your servo wire."

"All working,  needed to reconfigure the motors. I was  following the instructions for the Hoverthings Flip build but I think the bit about the Pixhawk motor setup guide may need revising? Thanks for the help. "

"Thanks and that all makes sense so back to the bench!
Cheers.
Peter"

"Just had a look at all the settings and the RCMAP channels look correct and they all move correctly in the Radio calibration test. My RC Channels are Pitch 2, Roll 1, Throttle 3, Yaw 4. I have set the RC trim values for 1, 2, and 4 at the mid value…"

"Hi Rob.
Thanks again for your help. Your fix seems what I'm looking for and I will make some adjustment and get back to you."

"I have the same problem with a X. Increase the throttle and it rolls to the left and becomes inverted without it leaving the ground. I'm new to the Pixhawk and ask if you could provide a bit more detail how changed the RCMAP setting??"
