I haven't found it here Olli. And at the start of this next month I am starting my build on one of these. Actually make that 4 of these in all since I am changing out my existing fleet using this mod. I will post up the results not only here but on the Vtail thread. If needed I can build a few xtras for other members as needed and will sell them at cost at the same time. IT seems once the effort is expended to set this up the remaining work is quite simple and only takes a small amount of time.
Can you post up how to set up the HH when you have time?
And in light of the problems still remaining a simplistic usb methodology might be needed. Your description of the changes in the VCCI0 pin need to be more specific for us simple guys!
