My quadcopter was flying very good in the past. The engines responded according the throttle setting and it was a stable platform.
A few weeks ago, i decided to update my arducopter with software V3.2.1.
After the installation of the new software i calibrated the stick settings and the esc again according the wizard of the MP.
After the esc calibration the engines corresponded according the throttle setting. To get out of the calibration mode i had to remove the power from the APM 2.5.
After connecting the power again I was able to arm the engines and they were turning on a low speed.
However when i increased the throttle setting the engines didn't spin up according the throttle setting.
I performed the stick and esc calibration several times now but that didn't solve the problem.
I somebody able to help me with this problem.
best regards johan

I can also confirm I am having the same issue on a Hobbywing Quattro 4x ESC. Was an older quad I built and had broke an arm on an accidental zero throttle command durinf final decent of a successful RTL. Finally got around to fixing this frame and updated to the new AP and firmware because am on a different laptop and did not have old AP or config files.
Have the exact same issue as Bernardo. Everything calibrates fine using the APM disconnect reconnect power method just as I used to. Then when I Arm the copter the motors spin up to say 10% throttle. I set mot_spin_armed value to 0 and now it does not spin on start but has high throttle the second the stick is off 0 throttle.
Using the motor test 5% 10% etc. and they spin at the proper speeds. Arm the thing and it's all haywire.
To complete my old post:
I installed six HW XRotor 40A ESC. (The black ones).
Now the Hexa is in the air..............and I'm learning the think in 3D :D
I had the wrong ESC, not ideally for Multicopter but for Heli.
Have always "Stabilize" in (the first) flightmode option.
Start, lift and hoover to 1.5 or 2 meters height - than switch to e.g. AltHold or what you like.
Hi,
as a newbie I can not tell what the problem is (sorry), I had the same issue and could solve it only by changing the esc.
(from hobbywing platinum pro 40A(blue) to hobbywing xrotor 40A (black edition).
now all is working good.
a "pro" solution is still pending........ -.-
Do you know the difference in hardware/firmware of those 2 Hobbywing ESC's?
I wonder if it's ArduC auto throttle trim doing something weird. However manually adjusting the values to try and resolve it doesn't seem to help either.
yes, the blue ones are better for heli's.
the black serie HW X-Rotor have dedicated function for multicopters.
No need to setup every parameter, only throttle calibration and the frequence can be calibrated/adjusted.
