"Well, my original 8mz board has arrived back (thanks Jordi) and works perfectly.
The 16mz continues to do the same thing - It's not just the MikroKopter, it's the same on my Conrad quad also.
I've checked connections again and again - replaced the…"

"Thanks Chris.
Yup, that's what the docs say should happen. Mine was sitting there with the LED on continuously, no flashing, all channels connected to a bound and working (checked with servo on throttle channel 3, which I believe is the important…"

"Same here, blue LED on the whole time, no ppm output. Also, nothing when jumpered for serial connection.
Flashed latest firmware via ISP, still no serial connection. Will test it for ppm later today, but I'm beginning to come to the conclusion it…"
