I'm French sorry for my English.
I'm trying to fly since 2 months with my jDrones kit. I could not calibrate gyro wih the Ardupirate code then I decided to download the Arducopter 2.x with APM Planner.
I downloaded every versions several times (2.02, 2.06...) but the only version I could use was the 2.017: I flyed 10 secondes with a yaw problem.
Today I downloaded twice the 2.0.20 like this:
- with APM Planner: Update check
- with the terminal (switch toward pins): SETUP and ERASE (result:done).
- upload firmware (at the end I can read: DONE)
- AC2setup: every thing work fine during calibation but when I make TEST with the terminal Radio values are false. Then I make new calibration with the terminal and after 3 or 4 trial radio values and imu values seems to be good in the test menu.
- I switch off the copter, change the switch far from pins and then plug the battery again: 3 motors are beeping (every 0.25 secondes). After arming only 1 motor run and after 30 seconds an other motor stop beeping and run normally but the 2 other never starts.
Do you have any idea to help me? Thank you
(I made individual ESC calibration 5 or 6 times)

Yes i think it's possible if you have a defectuous memory chip or a short somewhere on the board causing malfunction.
Did you try to connect the faulty ESCs to the two other channels ? What's the result ?
The opto recommandation is a general guide rule for safety and reliability, but your problem is not here i think, as most users don't have optos and can fly without problems.
I've seen you deleted your last answer, did you solved your problem ?
Seems like a hardware problem, a +5V powering problem or ESC problem. I would check the power supply voltage.
Wich ESCs are you using ? Check that they do accept 160 Hz refresh rate. Did you try them with motor test inside terminal ?
It is not normal that the radio test is not good. If the test is not right each time (you should try with another radio transmitter / receiver to be sure) then you have an APM hardware problem, or Power problem.
