"No problem :)
To be more efficient you need to find ballance between low kw motors, big props, light weight and big battery :)"

"POS_XY_P (shown as “Loiter PID P” at the top right of the screen shot above) convert the horizontal position error (i.e difference between the desired position and the actual position) to a desired speed towards the target position. It is generally…"

"You are testing in alt hold mode. You should try it in stabilize.
And your Alt Hold mode is not working due to completely wrong PID settings. You have all zeros in "Throttle Accel" PID. You must set default settings: P=0.5, I=1.0, D=0, IMAX=80
This…"

"Calc shows that you need 36 amps to hover. And your throttle is near 60% at hover.
My 800 quad with 3-axis gimbal needs 20 amps for hover. But it has quite efficient setup.
I would tell that it sounds right for me.
You can connect second 4S 6200mah…"

"He has each individual signal wire grounded. It does not matter where wires are connected - on esc or on pixhawk. And it not looks like out of sync. Too fast recovery.
Of course it would be good to check that there is no noise on signal."

"I was trying to say: if batteries was in parallel they will be discharged to a same amount. If one battery was disconnected due to soldering issues - it will be visible, that one battery is discharged more than another.
Bin files do contain all…"

"There shouldn't be dropout if one battery disconnects. It's a pity that there is no battery and current in this log.
But as we can see from screen that i attached - first thing what FC was done: increased throttle to almost maximum. Then copter…"

"Compasses inconsistent : the internal and external compasses are pointing in different directions (off by >45 degrees).  This is normally caused by the external compasses orientation (i.e. COMPASS_ORIENT parameter) being set incorrectly.
I want to…"

"It looks like hardware problem for me when viewing your log. FC controlled banking, but copter went to a different side. Same with pitch.Does all your motors spin good? Al escs are calibrated? And so on...diydrones_quad_crash.png"

"Your P looks too small and I too big.
I even do not like autotune results. In my practice best results are acquired with I ~= P/3. But it is just my opinion.
Your log confirms my opinion. It looks like pitch not connected to desired pitch. Same with…"

"It went full throttle? Or just started to climb up? Default RTL behavior is to climb up to desired height and only then navigate home."

"Hello, Andreas.
Unfortunately it is moving outside too :("

"Unfortunately I have Crius AIOP with MegaPirateNg installed. But i'm tired of all this bugs and ordered pixhawk yesterday. Now i'm waiting for the package :)I think that my Mega2560 is damaged. There is an error in verification when uploading trough…"

"Thank you for your answer. At first i've thinked taht it is it! I've measured i2c and got 5v. But then i googled and found that i2c on rctimer aiop outputs 5v. I can't find 3.3v road on board to test 3.3v. But i think that it is ok. My hud movements…"
