APM 2.6 does hold the esc Calibration

[AM_1]

I try apm 2.6 for the first time, I have got APM to arm. But the esc will not calibrate,  I have tried most thing even changing the ESC to HK 30A blue ones and updating the firmware with simonK. I have download  3.2 firmware to the board tried a different transmitter still no luck. The APM board goes thought the right process ie the LED';s start flashing as per the manual. The ESC bleep I remove the battery, and put it back on wait few seconds pull down the throttle, more bleeps and ever thing seems the motors all spinup. But If I remove the battery, I am back to square one all the motor are running slow speed and do not stop when the throttle is a minimum. I can calibrate the ESC stand alone no problem, but as soon as they connected to APM same problem. any ideas ?

Not quite sure what you are describing,  with  3.2 firmware the motors will spin up on arming.  This is not too high a throttle base level. If  you have calibrated the radio correctly  the A.P.M. will have saved your throttle settings.  The A.P.M. will arm in the normal manner.  If you dont want the props to spin on arming  go to  advanced settings and  hit find and then type motors, you should then get a selection of boxes one will be related to spin up on arm , reduce the value until the motors  stop spinning.

Hi All
I have resolved the issue, I have downgraded the firmware erased the eeprom via the terminal  connection and upgrade back to 3.2.1 and the motors are doing the correct thing now. They all in sync, and it had it';s first short fight today.  Thanks for reply';s
