"Hi,
I agree the prop adapters which came with the stock motors are crappy due to too much tolerance (gap). If you can find some metal or alluminum spacers as in the new prop adapters it should tighten quite well."

Hi all,I have just completed assembling the arducopter kit from JDrones and have been able to load the latest firmware .38. However I'm stuck with the ESC calibration. After completing my radio setup…Continue

Chow Kok Choy replied to CyberCrash's discussion Mediatek GPS with Battery like ArdupiratesNG"Hi all,
Yes I concur this will work. I was a bit apprehensive on why there's a need to cut the pcb trace but it appears to work as without the battery I can only get a lock on after more than 10 secs but with the battery mode, lock on is about…"
Chow Kok Choy replied to Chow Kok Choy's discussion ESC calibration"Hi all,
After 2 weeks of struggle I've been able to resolve this issue. Being a newbie @ RC flying I'm not familar with the 4 channels in the radio. To make matters worse I've two radios a Turnigy 9x (mode 1) and a Futaba 6j (mode 2).…"
Jiro Hattori replied to Chow Kok Choy's discussion ESC calibration"Hi allIn my consequence of setting up ArduCopter the 5V power source will be problematic, when you add XBee, GPS, Radio and so on. The one of the esc fed heavy load to those power eater. The behavior of IMU and XBee shows difference USB operated and…"
Chow Kok Choy replied to Chow Kok Choy's discussion ESC calibration"Hi Martin,
Thanks for your input. I don't think your problem is similar. I can calibrate my radio and also the ESC using the Mission Planner and have the motors running. As soon as I remove the lipo power supply I cannot rearm the motors again.…"
"Your Mux Mega 328 P is likely gone. Recently I messed mine up with a soldering iron while connected to the Lipo battery plus lead. There was a grounding loop from the USB and computer connection. The Ardu Mega will be replaced soon as well…"
Chow Kok Choy replied to Chow Kok Choy's discussion ESC calibration"Hi all,
I've still not resolved this issue of the motor/esc refusing to arm after a power down after completing the ESC calibration. My main computer is kaput and I not able to find the time to setup the arducopter again as I've…"
Gregory Rusakov replied to Chow Kok Choy's discussion ESC calibration"Hello, i have the same problem - when disconnect power and reconnect it again, the motors refused to run/arm. Could anybody solve this issue?"

Chow Kok Choy replied to Chow Kok Choy's discussion ESC calibration"Hi Arifin,
Thanks for your input. I've been able to arm the motors both thru the MP CLI method and arm the individual motors thru the RX method. The problem is when I power down and reconnect power again, the motor refused to arm. We have…"
Arifin replied to Chow Kok Choy's discussion ESC calibration"I think there are no any simple ways except you should test your esc manually, because we dont know and not sure wich one has a problem, esc or acm board. So please do a calibration test on esc using receiver, transmitter, lipo and a brushless…"

"1094 and 1927 looks ok for me. But the thing what you said that it will take some time to get solid number.. Hmm question goes why?? My numbers were also from Turnigy 9x with FrSky modules.
Easiest way to check that is APM capturing properly…"
Chow Kok Choy replied to AMENEN's discussion cRaZy arducopter PCB HELP!!!!!"Hi,
Don't know if my problem is the same. See my thread:

Can arm and run motor during calibration but on powering down cannot rearm motor again. Just assembled my AC2 kit from…"
Chow Kok Choy replied to Chow Kok Choy's discussion ESC calibration"Hi Jani,
Thanks for the advise. Here are my data for my PWM. Min and max values should look ok on Ch3 @1094/95 and 1952/53 however the max values start @ 1526,1740, 1847, 1901, before stabablizing at 1953. Could this be the problem? Data is…"

"Chow,
If APM would be broked, your motors would not do anything nor you cannot fly so it has to be on the settings...
Can you please check your PWM values at CLI.
Turn that small slider switch to CLI position (closer to RC…"
Chow Kok Choy replied to Chow Kok Choy's discussion ESC calibration"Hi Martin & Arifin,
I've tried lowering the throttle trimmer to 0, -10 and -50. The ESC calibration can arm the motor as per my previous post but on powering down and then reconnect power, the motor will not arm again. When…"
