Dear Sirs,
While trying to take off with S500 Copter at its first flight, it was always flipped over.
The S500;
We have checked the following items:
TX calibration,
ESC calibration,
Motor sequence and direction, and
propeller driection.
Flight mode: Stabilize
They were OK.
And we followed the instructions of initial aircraft tune to educe all the following parameters by 50%:
ATC_RAT_PIT_P
ATC_RAT_PIT_I
ATC_RAT_PIT_D
ATC_RAT_RLL_P
ATC_RAT_RLL_I
ATC_RAT_RLL_D
It was always flipped over and was over toward to right.
Here is the video:https://youtu.be/2PFLni_OZho
***We need your kindly help.
S500
Frame:S500
Motor: U3508 Kv550
propeller:APC 1238
ESC: HobbyWing 40A

I have calibrated the TX and ESC. The direction and sequence of motors were correct. However, the motor will not run until throttle was 20% in motor test process. Is that too high?
Post a .zip file with the files from the vehicle configuration directory created by the ArduPilot Methodic Configurator.
20% is too high for some ESCs but might be correct for some others. Hard to tell without the .zip file
Dear Sirs,
I have not used Ardupilot Methodic Configurator. But I found something interested.
The manufacturer of ESC told me that the PWM frequence of ESC is from 50~500hz. Have I changed the output PWM max & min to 50 & 500?
Don’t baby the throttle, give it a spurt to get it off the ground. If it still flips then the Motor order or direction is wrong, props on wrong, or the Flight Controller Orientation is not set right.
ArduPilot Methodic configurator detected that your board has a heater
If your board has a heater you should use it to get better results from the IMU, that is the reason it has a heater in the first place.
ArduPilot Methodic configurator configures the temperature automatically to 45 deg for you
Setting it to -1 would be a mistake and the software is not allowing you to make that mistake
You need to read the Documentation linked above the parameter table in the “05_remote_controller.param Documentation” area. Click on the blue texts
In those situations, un-tick the “upload” checkbox for the respective parameters and upload all others.
In the next page, use the “Add” button to add the parameter and give it the value you want.
