Well, I'm not sure how to continue! I have now had the exact same problem with and without the hott extension FW, so we can rule that out. It happened in FW 445 hott and in Max's new builds. It has also happened on two different M4's and two different adapter boards.
I guess this all points to the problem lying else where, but what should i be looking for. All these problems started when i changed the FC from AQ6 to M4. I have done hundreds of flights with this exact set up with a AQ6 and only ever had one problem, which was associated with vibrations, i have gone back and looked at the log of that incident and it is not the same as i am suffering now.
Could this be associated with the "hacking" of ports 1-4 on the M4. There does seem to be a difference between the ports 5-8 on the expansion board and 1-4 that i have hacked. For example when i power up the system the two esc's connected to the ports 3 and 4 initialise a few seconds before the esc's connected to ports 5-8 on the adapter board. In fact say 20% of the time when i connect power to the system, the esc's connected to ports 5-8 don't initialise at all and i have to power down and try again....
Or, could this be caused by a loose connection or bad wiring? I am tempted to take the whole machine to parts, inspect all the cabling and rebuild from scratch. But that is a big job! And i really doubt that the problem lies there.
Any one with any ideas i am all ears!!
