I've simply put in a return request for this board.

It simply will not pair no matter what.  Not going to waste time with garbage.  It would have been nice had it worked.  The "supplier" can't even answer questions!  Couldn't even provide a diagram or picture of what was to be wired where.  Response was, "I just sell them.".  Great!  I hope no one else spends their money on this!

I need to be flying, not trying to make some defective nonsense simply "pair" with either of the transmitters available.  All it ever did was blink.

Ducts are just about done.  Used 3/32 aircraft ply.  I may use some balsa strips to narrow the gap between prop tips and the ducts.

Have to also solder the original board back into place.  I take breaks and fly the other one when possible.  Still fighting trim issues.  Makes me want to go back to Glow Fuel R/C helos!  At least the linkages are adjustable to get it trimmed!  Have one still hanging.

Back to the work bench!

SF, Redfive,

I indeed have let it sit.  I checked all wiring multiple times.  When one finally comes to the realization that the component is all fouled up, you shift paths and recover the best way possible.

The issue was/is simple.  It would NOT communicate with more than one remote control.  It simply would not pair.  Only thing really lost was time and effort.

Nothing is lost other than a few $$.  The original controller board is going back in and the stronger Motor Units will be used.

She is either going to fly, or she is going to die.  I've had similar things occur with Glow Fuel R/C aircraft.  Usually it was a matter of antenna placement.  Moved it to another path and it worked.  These don't have that ability. 

The control board has been thoroughly looked over for bad solder connections, both for mine and for the overall board.  Nothing found even using a 12X Loupe.  Additional effort will not change this issue.

So I simply move on.
