Hmm...almost.


Continued experimentation with the little Li Di L6W hexacopter didn't quite turn out as I'd hoped.

As it moved away from the transmitter, the loss of control returned. It first loses yaw control and then flops to the deck, motors running.

I'd once experimented with installing a 2.4GHz router antenna in place of the very short length of coaxial cable which served as an antenna. That didn't seem to work and neither did replacing the coax with the one from another "toy" transmitter I'd successfully modified with another router antenna. That transmitter had the shield attached to ground even before I modified it.

Only the center conductor of the coax is soldered to the board which is another very likely culprit and I decided to try that setup once more with a new antenna I had on hand. Enter my friend the broadcast engineer! I told him exactly what I'm telling everyone now and he suggested grounding the shielding to the ground plane of the transmitter's PC board.

He cheerfully modified the router antenna's coax with a ground wire and plenty of exposed center conductor to solder in place. The job is, quite simply, beautiful and a continuity check with his Fluke multimeter showed it to be working perfectly. I'll get pictures and report back with the results.
