"Hi, I finally solved this, it was a parameter I had not been aware of, SYSID_MYGCS it was set to 253 on my copters not sure why as I don't remember ever changing it. It should be 255. Once I changed mine the joystick (RC overides?) started working.…"

"Hi, Did anyone figure this out?  I have the same problem with a X52, buttons work but none of the rc channels make it to the copter ."

"Hi,that seemed to do it. I found one motor had moved a little, very small amount, I re-leveled it and the effect is very small now, it is still there but not near as bad as in the videos. The motor mounts I have are for tubes but also need a hole…"

"Hi,I will check that again, it is using round CF tubes and I replaced the ones that came with it with some longer ones which means I had to drill or try to drill the holes 90 degrees from each other on either end which I found was almost impossible…"

"Paul,

thanks for posting this. I had been looking for one that could handle 6S. I have been stuck using 5v from my ESC on this copter. I ordered 2 to give them a try.  how are yours doing?

Something I do on the 3dr power modules is change the 4…"

"I dont know how easy it would be but couldn't he put an inverter between pin 3 and the signal it invert the signal?

"Hi,

I was just thinking, what about the Pixhawk boards?   should they be batt powered before using USB? I am not sure if it is even possible, at least for loading FW. For FW it seems the board has to be disconnected from power then reconnected.

I…"

"Hi, Yeah, mine are all 3dr boards.

thanks again,

John"

"Alex,

thanks, that's what I thought. I guess I got lucky.  I wonder if it is maybe poor power on the USB source that could be causing this problem. Just wondering cause I usually use high end motherboards and power supply in my PC, maybe this is…"

"Hi,  Weve had a pretty bad winter so I havent messed with my copters much this winter, I just found this thread and was a bit concerned because when I upgrade FW or download logs I bring the copter over and plug it into the usb while everything,…"

"Hi,

Could someone please help me. I have a quad with a pixhawk on it with 3.2-rc2 (beta) loaded. I have been getting unexpected rtl's on it. well I am guessing it is RTL's, it happened 2 times on this log. the first time when I lost control I hit…"

"hI,

I was just wondering, when using a new TX radio should the ESCs be recalibrated?
