"Yes I would get the RX working on its own, just pull out the wires and connect up an ESC or battery with a servo and get it working with TX before trying again. If the RX is not working, I dont think you will have joy with the motors."

"Receiver side looks good, I am a little worried by the wires on the far side of the APM. Difficult to tell but from the pic the power wire from the ESC/PB looks inverted. Shoulp be black in bottom row red in middle.... could be the angle of the…"

"On my system (Windows 7 64bit XP-VM) I have to attatch the USB device to the XP Virtual Machine. Only then can the Configurator use it.

I also have LPT1, but also USB devices.....

Are you using Arduino to compile in the VM or on the Mac? If in the…"

"Well Blake the good news is when I recalibrate all of my ESCs with the Spektrum setup it all works perfectly! For some reason it doesn't seem to like the FrSky, even through all of my original calibration was done on that.

There are also a few…"

"Looks like it is the M2MPower ESC's that ship with the kit. Just swapped one out for a Turnigy Plush 25A and it works fine. The other three just M2Ms just sit there and twitch. Looks to me to be a timing issue, as the ESC times out whilst the APM is…"

"Yes... it is really strange. I always connect Lipo first, even if I want to program. I connect USB port second.

Funny thing is I can go into configurator and send a motor command then everything works great.

I have a full backup APM/OP, I just…"

"Hi Robert,

I am also using 64bit Windows 7. I tried for days and just could not get it to work. In the end I created a Windows VM for XP on my 64 bit system, and installed everything there. It now works perfectly. It may seem like a pain, but in…"

"What is you timeout value set to? Try using 9 seconds or higher. Mine defaults to 5 which is too short a time for the APM to reboots and be picked up by the configurator as being active."

"How does one know if the MUX if blown?

I am having a problem where the motors wont start up unless I have the USB cable plugged into the PC."
