Changing between flight modes can be achieved by simply toggling one of the four DIP switches, no PC interface needed!
I received my i86L yesterday, and this thing seems super simple! I only glanced at the manual, strapped it to my 350mm quad, did the quick calibrations for Stick Center, ESC Throttle Range (again with the flip of a couple of switches), and without adjustments to any of the three gain POTs it flew like a dream.
I was able to flip, roll, and loop right out of the gate, so the acrobatic potential for this thing after some fine tuning of the Gyros, should suit my needs just fine.
i think this board is super for beginners. I bought a V 3.0 KK board from HK for my first quad and found that it was a pain in the a.. to set up, i also bought a i86 board and with those dip-switches it was in the air after 2 hours. And it still preform great.
