switch your camera to macro because its all blury and I cant see anything.......
Every web search I did shows that crazy head setup but nothing with a good
easy to see picture.
Besides how do you know that those links are the problem? Are you getting
consistant readings with full negative collective and full positive collective?
Usually you can set full + and - to your 12 degree pitch using the links
off the servos, and end up with 0 at mid.
I think you should work your way back down and try adjusting the main
links from the servos. Concentrate only on getting 12 degrees at full - collective
and full + collective. Then you will end up with 0 in the middle.
EXI kits are better than Esky kits. What a different head design. I might think
about removing the extra linkage if it was mine......
